Great guide - many thanks
Read all 500 posts this afternoon.
Got home and very quicly got my e2180 from 2.00GHz to 3.00GHz.
Just had to order a Scythe Infinity and some Artic Silver 5 before I go any further (on standard cooler).
Many thanks again.
:rolleyes:
How come after changing the FSB to 380 and setting my RAM to 5-5-5-12 CPU-Z still shows it at 380? I had it at 388 and even 400 but the RAM just ain't changing :)
I got 2 sets of 2 GB each OCZ gold pc2-6400
Great guides Clunk
Been a bit unsure on o/c but thought might aswell :)
get my e6600 quickly to 3Ghz on AC pro and as5, core temp reports idle temps 23-25 (TAT records a few degress higher) which i think is quite cool. When i run Orthos in the first 2 mins the temps are like 62 and rising which is not good.
Voltage is set on Auto, CTemp showing 1.35v and CPUZ showing 1.425.
The real question is do i have to re-seat my cooler as i have done it wrong?
First time i have replaced a cooler :)
Your temps are probably about right , using an AC cooler and also leaving vcore on auto.
The Auto setting is fairly conservative, in that it gives probably more voltage than needed.
Go into Bios & check what vcore tells you in there. Then set the vdimm in bios to the nearest setting to thhe value shown less 1 (you might try 2 if you want) , test stability with orthos, you should see your temps a degree or so cooler.
Other alternative is to get a more powerful cooler if you want to go further.
luck:)
I just thought I'd add my bit :)
Thanks to the OP for an excellent guide.
With a bit of fiddling I now have totally stable (so far!) system with my Q6600 running at 3.42GHz and my Corsair XMS2 PC6400 RAM running at 912Mhz (5:6 divider, 380MHz FSB).
Using Core Temp 0.95.4 peak core temps are around 61C but seem to hover around 57C most of the time and idle temps are around 35C. I could probably take it a bit further but I'm very happy with the performance as it stands.
It probably helps that the Antec 900 is less a case and more a collection of large fans!
Glad it was of use to you :)
back again people with same problems with new gear :(
this time around with the new 700w power supply, antec 900 case, p5k-deluxe/wifi, go stepping Q6600...
my dilemma is overclock @ 3ghz ran perfectly for 8hrs with 4x sp2004 with no drama's.. temps on everest home, coretemp 0.95.4 were 51-49degrees and speedfan measuring volts.. until last 10 minutes of the 8hrs i installed asus probe II to double check my voltage.. opened APII and apprenetly my motherboard temps went from a stable 8hrs 27-28deg to 187degrees... when this happend my system temps went to -65degrees and the random AUX temp reading went from 127 to -65degrees???? in speedfan 4.32 and in everest they completely disapeared???? this only happend "after" i installed asusprobe??
next part of my problem.. now on stock bios settings i keep getting voltage drop on +3.3V goes all the way down to 0.02V... whats going on?? i must have dodgy copy of asus probe II??
please any advice would be fantastic...
uninstall asus probe:lol:
Some useful feedback on this board.......having just had to swap one (fortunately under warranty)...
I updated the BIOS using the Windows update option and it screwed the BIOS boot section......would not even recover using the crash recover option at boot up, just simply dead.
The learning is two fold - NEVER update BIOS from Windows, Use the DOS option, or if your board supports it update via BIOS (as this board could, silly of me not to use this!) Its safer - Trust me..
Second - Always get a board that has a pluggable BIOS chip, I had a P5K Deluxe with a soldered BIOS chip, so couldn't even spend $25 on a replacement!! (Lucky mine got swapped under warranty! and swapped for an SLI...heh heh...:rolleyes:)
One thing about asus the ez bios update is the best flash routine i've seen. In bios - (see tools) no need to boot from floppy. I think the windows update method is risky on any mobo.
Must agree though i prefer the old bios chip & socket., it's quicker to have a spare bios chip than having to rma the board.
luck:)
Hi all,
I just joined this forum, mainly to thank the OP heartily for all of the wonderful advice on how to OC my new Q6600 and P5K Deluxe WiFi, but also wanted to let others know that I, too, recently bricked a motherboard (a basic P5B) using the BIOS update in Windows. It is the first time I've ever had a problem using the Asus Update in Windows, but it's the last time I'll ever use it. Still, I was going to get rid of my P5B anyway, as I wanted a more robust mobo to do overclocking on.
Anyway, on to my thanks! Thank you SO much for your help, Clunk! With your advice, I've been able to get a stable system running at 3.7GHz on air (Antec 900 case, fans all on low) that idles at 31C. I might even be able to go a bit higher if I get some good OC'ing RAM at some point, but my most recent spending has put that on hold for a bit. So, thank you for giving me a system that far exceeded what I'd have been able to do with my existing knowledge!
-z
Thanks, and I'm glad it was of use to you :)
Quite :)
Some stats would be nice. Vid, Vcore, Temps at load, how long it was stability tested...
I'm jealous, though not complaining about my 3.4 clock - now stable for six weeks running mostly 24/7 with full load for about half that time, in blocks of around 12 to 24 hours.
I guess I probably should have put "stable" in quotes, like I did just now. My system does not crash under any of the applications I run currently, the most intense of which is video conversion, which still isn't very taxing on the system, but I can fill in a few blanks based on what I've seen:
Vcore is 1.4375V, at the heaviest loads I've watched (I use a core monitor in my sidebar) which have only maxed out a couple of the cores for a few minutes, the temperature gets to right around 50C, but usually stays just under that. Vid, is that short for video? I don't have any video so far, but I can take pictures of different things. RAM is middle of the road G.Skill, 4GB of F2-6400CL4D, DDR2 800. I can get the timings to 4-4-4-10-2T (from the standard 4-4-4-12) and run it at 2.1V. With my current overclock, I think that makes it DDR2 820 (1:1 timings). I should mention that mine is a G0 Q6600, also, although I'm sure you all assumed that if you're keeping up with the latest chips (and in a forum like this, I'd bet most of you are!). There's nothing else special about my setup, and everything is taken strictly from Clunk's guide. I use AS5 and a Zalman 9500 HS/Fan combo for my CPU. I did download OCCT and it won't run for more than five seconds, so calling my system "stable" is a bit of a stretch. I should say that for what I typically do, which is not that taxing on my system, it doesn't crash, and doesn't run too hot. I imagine that if I wanted a truly stable system, I would probably have to drop it back to something more like what others are running, in the 3.4GHz range, or perhaps increase the Vcore even more, which I'm hesitant to do since I don't like getting my CPU too hot.
Everest works for me so does MBM
mbm5 it doesn't list my p5k-d in supported mobo's :(
It works with my p5k dlxe so odds on it works with your, up to you wether you try itQuote:

VID - Voltage IDentification: A code supplied by the processor that determines the reference output voltage to be delivered to the processor. IOW your cpu's nominal Vcore, aiui. It /might/ give some indication of overclock abilty. Coretemp will display the value.
Ouch. I'd not be happy running like that but each to their own.Quote:

If you're not taxing your system, why overclock? I'm puzzled now. If one OCs for a performance gain, you'd get the same result just by pushing it harder but without any hassle or risks whatsoever.Quote:

We dont need the overclocking police in an overclocking thread :lol: :)
I personally do it for a bit of a hobby, if people need the extra speed, then thats an added bonus, but I think with these C2D and Quad chips, it is criminal not to overclock them...but that is just my humble opinion :)
Well, I've noticed performance gains with every speed increase I've tried that managed to boot and run stably. However, I do see your point. I will most certainly drop down the speed if it begins locking up on anything I do regularly. Eventually I'm going to end up replacing my RAM, and then I'll OC my system to a level that is rock solid and stable regardless of what I throw at it.

does not compute , pushing it harder how??Quote:

Oh you mean overclocking it??
:lol:
gah this MBM5 is giving me a head ache... none of the sensors work correctly... :(
EDit: supershanks what sensor number was your vcore reading in voltage??
Voltages - Tab
1st one.
Temps - Tab
Sensor9 = Core 0
Sensor 10 = Core 1
Sensor 11 = Core 2
Sensor 12 = Core 3
my first voltage sensor gives me reading of 2.64v and 2nd 3.41v 3rd 3.28v.... identical to everest.. 1. cpu core 2. AUX 3. 3.3v readings.. as for temp sensors only thing that gives me a reading is motherboard temp.. tried #9-12 on custom and all other settings??
have you installed as:-

hi, read your guide was really good, i seem to be having a problem though.
I have the P2KC mobo and changed all the settings as shown in the screenshots and so forth, but whatever happens i cannot get the ram to fsb ratio to change from 2:1. Currently cpu-z says my bus speed is 200mhz and my ram frequency is 400mhz a 2:1 ratio.
If possible i can provide screenshots of my bios, but whatever i seem to do i cannot get the ratio to change as a result cannot clock my board.
Thanks in advance.
You mean the P5KC?
Up the FSB to 301 and you should see a 1:1 setting in the dividers.
Also, make sure your BIOS is fully up to date.
I wasn't questioning the general reasons to OC, only what the purpose is if the specific machine in question isn't ever pushed, but then I guess you'd overclock your machines even if you never planned on switching them on :p
Having thought about it though, I guess it will still get stuff done quicker (yeah, I know that's obvious) even if it never gets above 25%. I'd get my coat but it was destroyed when I jumped off a tall building in another thread.
Hm, no scowl smiley.
/scowls menacingly
I meant if your use cases never push the cpu above 50% load, say, you can get more benefit from modifying your usage patterns &/or software to push cpu load upto 100% than from a typical overclock. Of course doing both is a reasonable option.
hi, thanks for the fast reply, i did mean the P5KC, i change the FSB to 301 and it did change the FSB:DRAM ratio to 1:1, however regardless of what i put the fsb at as well as it syncing with the ram, it still wont budge from its default.
I now have the FSB set in bios at 350 with the ram at 700, which is right but in cpu-z it still says it is at 200 bus speed and 200 memory frequency.
anymore ideas would be great thanks in advance.
p.s. i have flashed the bios to the latest version
Right i see where your coming from interesting view . How you utilise your load is i think, though a different thing to overclocking.Quote:

Overclocking effectively increases the capacity of the component(s) beyond it's specified level.
You can argue if you just browse or use office etc., then you don't need to oc, if you play extreme games an oc might be useful, i can see that , but overclocking to a large degree is done:-
1) An intelectual exercise , maximising the potential of something, in the 50's 60's it was the car, now some of us keep our hands clean.
2) getting something for nothing :D
3) Competition to show prowess etc.,
luck:)
Clunk me ol' mucker - i'm not out the woods - the problem has come back, i've got a single drive in my RAID 0 array dismounting whilst windows is running. It's perhaps less frequent but it's def doing it (i.e. when you reset the intel RAID BIOS lists but one drive).
I think i'm going to try changing the drives this w/e - legacy usb off/dvdr still not plugging in btw.
Still on the 311 bios.
Great guide Clunk!
Got pretty much the exact same setup as yours, same mobo and processor got 2GB Geil Ultra Low Latency RAM.
Having a bit of trouble though,
Whenever i raise the FSB over 380 it won't boot at all.
I'm running at 380 at the moment with idle temps of mid-high 30's idle and mid-high 50's on full load.
Was wondering if anyone knew of a reason why it might not like a higher FSB.
Thanks,
Iain.
When you say it won't boot at all, that's a bit ambiguous, at least to me. If it won't even POST, then that's more than likely a RAM issue, whereas if you get a BSOD somewhere in the bootup process, it could be the RAM, the CPU, or both (or maybe even the mobo isn't getting enough juice, but at 380, I'm going to say that's a very unlikely possibility, since I never changed those settings on my P5K Deluxe). So, if you're not getting it to post, it's probably the RAM timings, as I would guess you're giving your RAM plenty of voltage, yes? If it's blue screening, then I'd give the RAM a bit more voltage, or the processor, or both. My system is clocked at 410 FSB, running 2.1V 4-4-4-10 DDR2 800 RAM that is a very poor overclocker (I'm actually surprised it got to 820). The RAM is rated at 1.9 to 2.0V. The Q6600 is getting 1.4375V currently, and is stable for the workload that I give it, which admittedly isn't very much. Idles at 32C, peaks at around 50C.
As I've not learned as much about RAM and how tolerant it is of voltage increases, I'm hesitant to give my RAM much more voltage, but might if I find information that can make me feel confidant I won't fry my memory.
-z
Hi guys ,great tread you have going on here, well to the point I giess ... I have a Asus P5K-E and a Q6600 and i cant change the multiplier (it says unlocked BTW) and cant change the fsb. is it that my boars is not leting me do that, or the proc? I have tried everything you guys said in the tread but i can get this thing to work.im tempted to go buy another MB and run this one over with the car,any help will be greately apreciated.
Cheers Zmonkey,
The ram is rated to run at 800Mhz and the advised voltage is 2.1 which it is manually set to, I would of thought it would of been able to run at 800Mhz with the rated voltage..
When i say it doesn't boot either, it turns on but a blank screen appears, afer 30 seconds it'll reboot and do the same thing, the only way i can get past it is resetting the bios.
Any further help would be appreciated,
Thanks,
Iain.
Ok, a blank screen with no text means the board is not posting (that's the term used when the BIOS initializes and begins the bootup process by identifying the basic hardware of your system and identifying a bootup device such as a CD, DVD, hard drive, etc.). I, too, had this problem and found it to be RAM related. If you are set to 1:1 timings, a 380 FSB should be posting your RAM at DDR2 760, which at the rated settings for your RAM (voltage and timings) should boot without a hitch (I know this because I've had my memory underclocked for months while running a E6600 at 1:1 timings which I could only get stable at around 3.5GHz and it ran MUCH hotter!).
So, my best guess is that you aren't setting your RAM at the 1:1 timings. At 380 FSB, you should be able to select DDR2 760. Give that a try and see if it boots. You can also give your RAM another .1V above the max rated voltage just to be sure it has enough power to run properly, although that really shouldn't be necessary (I always set mine .1V higher, personally, but again, it probably wasn't needed.). Also double check and make sure the different Enabled/Disabled options in Clunk's guide are set properly, as many of those can severely limit your ability to overclock. Finally, after you've done all of that, if it still doesn't post, then start dropping the FSB in 10MHz increments (370, 360, and so on), just to see if it will post at some lower overclocking. I really doubt that should be necessary, though, and I could certainly be missing something, as I'm still pretty much a novice at overclocking. Hopefully if I am, someone else will chime in and fill in the gaps in my analysis or correct any errors I might have made, but I do feel that these suggestions have a good chance of solving your OCing issues, and that 380 is definitely a reasonable overclock given your system.
Good luck!
-z
I think maybe you've missed a step or two in Clunk's guide, as there are some settings (some of the ones you set to Manual) that will open up a lot of other options, including FSB settings and the multiplier. My guess is that you're looking at the wrong page in the BIOS. Go to Advanced>JumperFree Configuration>Ai Overclocking and set that to Manual. This should then allow you to set your FSB, etc.
Best P5K guide period! Found it on google!
Nice Guige also found on Google Thanks for those nice pic's on the Bios! :)
I have 1 minor problem on this Asus P5K-E Wifi when i change the settings in Bios save & exit it wont post unless i turn off the power supply & re-start the computer?
This happens after Bios exiti & Exit from Memtest, otherwise all is well??
The Overclock values & settings aren't lost so not much of a problem just annoying!
I never had this problem with the Gigabyte 965P-S3 motherboard.
I will try it now and see what happens thanks
still not managing to actually overclock my cpu, as previously stated on my post, regardless of what i set the fsb and ram at it will not budge it off stock, any ideas?
just reset the cmos and now not even a post screen....this mobo seems to be terribly unstable, RMA'd it once but was tested and "fine" so got it sent back, has been booted and stable at stock but now i have reset the cmos not getting anything but a black screen.
Any ideas would be greatly appreciated
thanks
well no luck, cant change the fsb or the multiplier, could it be the motherboard its locked somehow? the fsb its not greyed out it even says on the side that you can change it, but nothing.... or the proc might be a no good one,who knows. I even used the beta bios and the 808 bios but no luck. Im getting ready to trow this thing out of the window and go AMD (minus the video cards HDDs and psu?.
Ok,
Tried it again,
Upped the RAM voltage but still no joy.
Took some pics of the BIOS however,
If anyone sees anything that shouldn't be enabled/disabled let me know, as far as i know it's all right.

Why is the CPU voltage set at 1.35?
It's running stable, i've had Prime running for 12 hours with no errors...
So thought i'ld leave it like that.
Would you suggest increasing it then?
I do increase it when i raise the FSB but no matter how high i increase it still doesn't boot..
This is a screenshot of CPU-Z..
I remember that i had problems originally with the voltage, it was showing a hell of a lot lower on CPU-Z and on Asus Probe so i increased it higher in the BIOS to raise it a little,
Here's the screenshot.
http://img237.imageshack.us/my.php?i...3642871yh4.jpg
@IainM: Yes, for 380 FSB, I would recommend at least 1.4V, maybe even 1.4125V. I run at 410 FSB and have my voltage set to 1.45V, which has little effect on the temperatures (raises them about 2C from a 1.425V setting). It's also worth mentioning that if you can find the settings for those five DRAM settings after your 4-4-4-12, it can stabilize your system quite a bit. I tried leaving those on auto, then putting in the "suggested" settings from G.Skill's forums, and found I was able to tighten the timings a bit and even overclock the RAM slightly. Now, what I've discovered is my RAM at stock voltages will only OC to around 416 FSB, so at 410, I'm playing it safe. Before I changed those auto settings, it would lock at anything past DDR2 800.
@logo113 & bbarnes: Sorry guys, for your issues I have absolutely no idea what could be wrong, especially if you're following Clunk's guide exactly (I've followed a few different OCing guides in the past, and Clunk's is as good or better than any other I've seen, and I don't see a thing he's missed as far as the P5K is concerned).
-z
Ha I'm dumb, i figured it out, in order to change the fsb and the multy you have to TYPE the number, I feel like an dumb***!, thanks guys for all the help. now to work on the HD 2600 HTs!!!
No worries, logo113, glad you got it sorted out. I understand what you mean, though. I'm used to doing the +/- thing on most of those menu options, also, or sometimes enter and pick from a list.
The RAM setting are as stated on the package.. I increased the Voltage by .1 aswell but as soon as i go over 380 FSB it just won't boot at all..
The system has run a good 12 Hours of Prime at these settings so i'm pretty sure that it is stable so is there really any need to up the CPU voltage?
lost my rag completely yesterday with it and went out and bought a new motherboard,
Gigabyte GA-P35-DS3, installed it booted fine and is now running my 1.8ghz core2 at 3.2ghz stable, rang my supplier for the asus mobo today they have given me another RMA but im not holding out much hope for a refund as i have send it back before and they have said nothing.
Lesson to be learnt here is dont buy a state of the art new asus motherboard, sticking with my trusty gigabyte from now on, thanks for the advice and help anyways pretty sure now its defo a dodgy motherboard.
@bbarnes: There's always a chance of a hardware defect when it comes to computers. I've had plenty of RMAs in my lifetime, and have had very good luck overall with both Asus and Gigabyte. Still, there are always nightmares. My most recent were a bad ethernet port on my P5K (Basic) which prompted a trip to CompUSA to get the only other board that had the OCing abilities I wanted (the P5K Deluxe WiFi). I couldn't be happier with the new mobo, though! Also, in the process of upgrading, I bricked my P5B with a firmware update that I ran through the Windows updater, and then after placing a tech support call and leaving a message, never got a call back. I finally just decided to avoid the hassle of a repair to potentially sell the mobo to someone and trashed it. Still, once you find that perfect combo, it sure is nice to have a system that purrs. :D

Very helpful guide to overclocking!!! I just got the ASUS P5K Premium mobo , so I will follow this O.C guide carefully..I promise..:)
Any more advise for ASUS P5K Premium users..?
How do you get the RAM to run 1:1 on the p5k-e, the lowest option is 677 and if i raise the fsb it just raises past 677 there is no lower option and running everest and cpuz comfirms it's running at the speed it states in the bios.
So I got my Q6600 G0 running at 3.72Ghz (9X412 @ vcore 1.4625) with temps of around 25C each core (custom water cooling). My Ram is set to 5-5-5-12 @ 1.21V (OCZ Gold 2 X 2GB dual shared)
Now it runs stable under Vista 64bit but once I restart the pc it won't boot for some reason unless I press several times ON/OFF :)
Could it be my vcore?
For specs on my pc check my signature...
Not seeing your specs there TurboTronix.
What PSU are you using?
I think if you click on my name to see my public profile it will show it.
My PSU is Antec Truepower Trio 650W
Ok it shows it now...
Hi,
today I put my new system together and did some stressing
so far on p5k-e my Q6600 G0 is @ 350Mhz / 1.35V | Crusial Ballistix PC2 6400 @ 1050Mhz / 5-5-5-12 / 2.2V
divider is 2:3 as you can see
other spec: Thermalright ultra 120 extreme with tricool 120cm, antec p182 with 4 120cm fans, corsair 620hx
stressing with orthos for about 30min gave me temps:
- mb max 53 (idle 37)
- cpu 59/58/54/58 (idle 42/45/37/39)
is it too high or it's ok? Especially the mb temp is getting me nervous...
Can I go any further or it's all I can do? Isn't the cpu temps too high with this hs? I've heard it should done better... Maybe I put the AS5 not properly? Could you link me to some site that shows how to properly install heatsink for q6600?
I have noticed 2 strange things:
- mb temp at stressing went for like 30sec at 171C O_o then it went to -95 (minus)... what's going on? Is it damaged or maybe some voltage uping needs to be done?
- at normal work probe warned that vcore dropped to 0,02 (then suddenly went to normal), after a while it again dropped to 0,31 and again went normal in just a sec
i enable/disabled some bios settings as was recommended here
except vcore / ram volt / pll other voltages bios settings is set to auto... should I change something?
last question - what is fsb strap and what settings do you recommend?
edit: dunno if it's important but I'm using 4x1gb sticks in my system
anybody? :surrender:
You wrote 350MHz. What did you actually mean? I guess either 3500MHz, which is a pretty high overclock on air for a Q6600 G0, albeit not unheard of, or 350xM for some multiplier M which you didn't state.
What are you measuring the temps with? What OS?
Coretemp gives accurate results aiui.
As to safety of the temps, if they are accurate, I'd not want to be running 24/7 around 60, but some people seem okay with that.
sorry for not specifying it - 3.16Ghz (350x9). I didn't wanted to try get it higher as I wasn't sure if MB temps aren't too high (???) ...
I measure temps with speedfan 4.34 beta 34, coretemp and everest ultimate
I know 60 is high but while playing some advanced games it doesn't go over 55... You think is still to much for it?
and what about this strange vcore warnings? Speedfan doesn't seem to notice that there is any drop... maybe it's not measuring it so frequently as asus probe? Maybe you know of other application that monitors vcore constantly and provide some graph/statistic over time?
could somebody answer some of my questions please? :P
I'm also interested in the Northbridge temps.... I'd assumed 'MB' in asus probe isn't the northbridge but rather board temp? Reason I say that is I have a waterblock on mine and it still hits 55c. with a huge fan blowing on the motherboard it drops alot, obviously with a waterblock the NB wouldn't drop hardly at all.
I also read the sensor for board temp was very near a mosfet for the RAM or something, so could explain high MB temps?
Can anyone confirm this, and if so - how you can measure the NB temps?
blinking, try disabling 'vdrop' in the bios - it's near the CPU voltage.
Thanks
finally some nice answer! ;)
it might be true that this is measured somewhere near ram mosfet as my rams do get really hot
you mean I should disable voltage damper? Could you please explain how will this help?
Hmmm, sorry... Think I messed up a little when I said that!!
Enable the Voltage Damper, ( if it isn't already? ) that should keep your vcore from dropping too much under load.
I've had vcore warnings on boot, it seems to be a problem when the vcore goes above what you set in the bios. I don't think you need to worry as long as you're happy with the vcore level. Assume you have it set quite high to get that error??
I'm as unsure on you regarding MB temps though. I don't think MB temp is the northbridge though, judging by my setup.
unfortunately v damper is enabled :P
I get this vcore droppage error really occasionally (it drops to different values, from 0.02 :surprised: to 0.95) but don't know if I should worry about it or not... Strange thing is it occurs only while normal usage, when stressing with orthos (all 4 cores) it never happened...
I tried setting vcore to auto and to fixed values, it didn't helped
today I changed the orientation of ultra 120 extreme so that now fan on it is blowing toward ram and temp on stress is now 45 which I guess isn't so bad
I've now got my Q6600 running at 3.6GHz with a 400MHz FSB and a VCore of 1.392 (current on auto in the BIOS). Tonight I plan on tweaking the voltage down a bit manually as I had to turn the fan speed up on my Tuniq Tower 120 when I upped it from 3.4GHz. Peak temps with all cores fully loaded are around 65C currently, idle around 32C. I have an Antec 900 case so I think dropping the voltage a tad, turning the Tuniq fan down to min and putting the 200mm case fan on it's middle setting should be nice and quiet and fast while keeping temps under control.
The current setting are stable under OCCT and Everest stress tests. It actually runs cooler than my friend's QX6850 at the same speed but he has a lesser cooler. It'll be interesting to compare them once he's upgraded to a Tuniq 120.
The recent drivers for my 8800GTS also mean I can overclock that a lot more too. I think I got a good one as I can run it at 680Mhz for the core and 1000MHz or the memory, standard settings are 512/794 or something.
The net effect of this is around 12500 3DMark06 marks on default settings.

I dont get why I have to set my RAM speed down from 800MHz(my current RAM speed) to 667, just to get the RAM at 1:1. Can someone tell me why, I meen why should I slow down my RAM? To get my normal RAM speed, i have to set my FSB to 400MHz. I have no plans to overclock my CPU that much.
And is it important to Flash the BIOS?
I forgot to say: This is the best guide EVER!
The reason you slow down your RAM is to compensate for any OCing you do to your CPU. In some cases, you can overclock your RAM nearly as much as your CPU, but that is usually for fairly tame OCs of the CPU. In my experience, RAM is much more difficult to OC well, as it heats up much faster due to a less efficient cooling system (which is normally just a heat spreader over the module, and then whatever air flow you can manage for it). However, with decent RAM, it is often possible to tighten or loosen the timings of it to have it perform at an optimum level based on your desired CPU overclock. Also, it's not necessary to set your RAM to 1:1, but it does help to ensure a stable CPU overclock with no worrying about the RAM. After you have a CPU speed that you're happy with, then you can start changing the ratio and working on getting the RAM at the level you want. Keeping the RAM at a 1:1 ratio ensures that the RAM is always underclocked except for the most aggressive (>400) FSB settings.
:bowdown:Hello guys, and greetings from Norway!
First of all, thanx a bunch Clunk for your effort. Your guide is fantastic! :mexican:
Then to my problem.
I am experiencing the exact same problem as described by mark319 in post #61 in this thread (it is the first post on page 5). I am not allowed to quote it or link to it as I need 5 posts in this forum before doing so.
It is extremely frustrating, as I was looking forward to clock my brand new system. The very strange thing is that I was overclocking using AI Suite yesterday, and all changes I made to FSB did indeed raise the the core clock. I was actually running stable at 3.2Ghz.
However, I wanted to continue clocking in BIOS, so I uninstalled AI Suite. From then on I have had the same problem as mark319. I have installed the latest bios, but to no avail. I have even reinstalled AI Suite, but it does not work any longer.
- I have set the correct memory timings and Dram voltage
- I have Dram frequency to the lowest setting
- I have tried to increase the FSB by only 10 to see if it raises the core clock - it does not
Still no go. Whatever I do, the core clock will not increase :-(
Anyone have any clue what's going on here?
Just to let you know. I solved the problem by doing a hard reset of the cmos. Phew...what a relief :-)
Argh...today when I booted my system I got an error message saying "Overclock failed", and the problem where raising the FSB bus dos not raise the core clock is back (in black). Really frustrating. Why do I get an overclock failed message when I successfully ran Prime95 for hours without failure before my last boot? Oh well...I just hope a hard reset of the cmos once again will enable overclocking.
If I understand how the hard reset of the CMOS works (and by this I'm assuming you mean you turned off the power switch on the power supply, then turned it back on, then booted), when you boot after that reset, without going into the BIOS and tweaking your OC settings, then what you're actually booting with is a factory default setting. By this, I mean there is really no overclocking happening on your system after booting with a hard CMOS reset. So, when you turn off your system normally and then turn it back on, the OC settings you used before are restored, but because they are unstable, you get that overclock failed message.
So, my suggestion is to tweak your settings a bit more and try to find something stable that you're happy with. Hope that helps!

Just Want To Thank You For All You've Written About Overclocking With The Q6600 And P5k...just 1 Question For Now,what Is The Bios Version I Should Be Using Now? Thanks Keebz
Huge thanks Clunk, for the guide.:)
Just have a few questions for new build.
I've only done minor overclocking before on AMD's.
Can't get my head round the 'divider' thing. ?
CPU-Z shows FSB 5:6 whether system at stock settings, or with BIOS FSB set to 360 & DRAM frequency showing 864Mhz
Is this RAM frequency ok?
Have run Orthos for 2+ hours in between increases, and all running fine.After 3 & half hours, SpeedFan showed CPU 51, Cores 41.
Left RAM at 5-5-5-12-Auto, set 1.9V. CPU voltage Auto.
Would like to make a last FSB increase to 375, as that will be enough.
Need to know if I have to alter RAM settings (or anything else) or can I leave them?
edit(Ok, have read Zmonkey's post. Thanks. Have reset FSB back up to 360, DRAM is now 720Mhz & CPU-Z shows 1:1. :)
Cheers,
Marmot
Clunk you are the dogs boll^&ks! Thanks so much for this guide. I was a complete nobo when it came to o/c. I’m now hooked on it and got my new system running pretty good :bowdown:
Q6600 GO with stock air cooler running at 3.0 GHz. 44 C at idle and 65 C stressed. Volts under stress (according to CPU-Z) 1.240v. First run with auto volts as suggested, then manual starting low and working up until no BSOD and Prime95 running for 6 hours. If you keep the volts to a minimum then your core temps are manageable :rolleyes:
Next bit of kit to buy is a decent cooler. Should be able to squeeze a few more MHz out of it! :)
Full spec:-
Asus P5K motherboard
Q6600 Go 2.4 MHZ running @ 3.0 GHz (stock cooler)
2 Gb Corsair XMS2 DDR2 800Mhz tightened up to 4.4.4.12 2T @ 2.1V
Inno 8800GT running @ core 700MHz, Shader 1.75GHz, Memory 1.0 GHz
Best 3dmark06 13385
Important note; You must run RivaTuner (or similar) when o/c a 8800GT. Setup a fan profile as the drivers currently do nothing with the 23% standard fan speed. Mine kicks in at 75% @ 65 C and holds it there :geek:
Once again, thanks for all the info.
Dave Pendo.
Excellent Guide
I am planning on building my first system and going straight to overclock:
These are the components:
Asus P5K Premium Wi/fi motherboard
Intel Quad Core Q6600 CPU
Ram OCZ 2GB (2x1GB) PC2-8500C5 1066MHz
Graphics card Asus 8800GT
Already have very good case and power supply and lots of sata drives.
My question is:
Is high speed RAM worth the money? for example: from reading the guide to overclock you basically have to increase the FSB as the multiplyer can not be changed. So I should get to 3ghz by changing my FSB to 333 and increasing the CPU voltage.
You also state that you have to lower the speed of the RAM - is it therefor worth getting high speed RAM (1066mhz) if you have to lower its speed? Will the RAM ever be able to run at its stock speed of 1066?
Thanks. eon
@ eon designs.
Something worth thinking about (I missed this when I built my rig) if you are going with an 8800GT is the PCI E connection. The 8800GT supports the newer PCI E 2.0 bus. A P5K board does not. It only supports PCI E 1.1.
I don’t think that the PCI E bus on the P5K throttles the 8800GT in anyway, as mine goes like **** of a shovel when o/c’ed. Also the GT is slower than an Ultra and the Ultra is not PCI E 2.0 (I think).
To be more future proof I would go with a MB that supports PCI E 2.0 as it handles a lot more data transfers than PCI E 1.1. As we all know graphics cards in say 1 year’s time will be twice as fast again and I guess these future monsters will be throttled by a PCI E 1.1 slot.
Just my thoughts.
P5k Deluxe Bios 0603.
Has any one tried it yet ?
THANK YOU!!!! I can't tell you how much I appreciate your hard work here. I have a p5k and Q6600 and I am not running it at 333 x 9 and my temps on cores 0 & 1 fluctuate between 63C and 65C, Core 2 58C and Core 3 60C.
I was seeing these temps on the stock setting so before I started playing with OCing I took my Zalman CNPS9500A off, cleaned it and added Artic Silver 5. That dropped my stock temps right away so I felt comfortable giving it a shot.
I didn't mess with OCing the ram but it's nice to get that extra 20% out of my CPU. THANK YOU AGAIN!!!
ONE QUICK QUESTION: When idling my Vcore is 1.35 and at full load it's 1.25 Should I manually set the vcore to 1.3?
(at stock settings the vcore was 1.25 idle and 1.15 at full load)
NEVER MIND, read further in the thread and found the "leave it to auto" comment. Thanks again...this is a great tutorial!
Thank you very much Clunk.
This is the best OC guide I'v ever seen, Sovled all the problems i had before.
I'm quite happy with the results,I have Q6600 OC'd to 3.0ghz stable.
Details: CPU 333X9=3.0GHZ, RAM 4-5-4-8 ,834MHZ
Right now i have FSB:DRAM 4:5
The question is that do i need to set FSB:RAM 1:1 ratio? If i try to set 1:1 ratio ,i have to either lower DRAM or higher FSB right ?
but I dont want my cpu to be pushed that far, 3.0Ghz is not that bad i think.Will 1:1 ratio give me a better improvement than 4:5 ratio ? noticeable ?
Sorry I cant post any URL's .
Hello , new to the forum and I am very intersted in your guide it looks brilliant .
I have never OC a machine before so am looking forward to some rewarding times along with probably frustarting ones as well.
Ok rigg as follows
Asus P5K Premium Balck Pearl, just flashed to Bios 0404
E6600 C2D with a Tuniq Tower 120 CPU Cooler
4 x 1gb of OCZ PC2-9200C5 1150MHz Reaper HPC Edition Dual Channel DDR2
Vista 64 Bit Home Premium
8800GTX
Ok i have follwed the first part of this guide in great detail but i have 2 questions , rememebr i am a noob here ok so please be gentle .
1. I have no option for disabling Intel Speed Step , either i cant find it or it dissapeard under the bios update ?
2.FSB / Dram ratio
I notice in your screenshot that you have a 1:1 ratio where mine shows this :

Ok i did say i was an OC noob and im sure i have set something wrong iin the bios , your help is appreciated thx
She looks fine to me. Sorry, did you have a question?
Hello all,
I am having the following problems:
- after a fresh windows install (XP) with the latest chipset,lan, etc installed most of the times my PC resets just before entering windows
- I am getting a "overclocking failure error" even if I did not touch any OC features.
I have done the followings without any help:
-updated the bios to the latest versio (updated,clear cmos, same problems)
-cleared the cmos (removed all the cables, removed the battery, put the pin in 2&3 slot for over 10min, load bios defaults, same problmes with restarting before entering the windows)
- disabled the LAN from bios, did not help, somethins it gets into windows sometimes not
-disable the onboard sound, same problems
- I have put to AI overclocking to manual, set FSB to 333mhz, multiplicator auto, ram 4-4-4-12, voltage 2.1V...EVERYthing else to auto.....and I still get resets and overclock faild
-sometimes after I pull out the powercord and close the PSU when I want to start the PC it will start for 1sec CLOSE and then start again
My pc specs: E6750
P5KC
Audigy4 bulk
2gb 800mhz geil ultra set to (yellow or black slots)
500gb WD
8800GTS
I am running out of options :(
Can someone please tell me if there is somethis that I can do?
PS: I would like to appologize if I posted in the wrong thread
where is everyone ??
Hello there everybody, im new here and want some help please..hope someone can come up...I had an intel system, e6300, and DG965 board, I upgraded it just 1 day back to Asus p5k-VM and bought an ASUS silent knight as well, now I have some problems, if everything is set to auto in the Bios and FSB is not increased, my idle temp is 60C!...vcore is 1.27, shown by system probe from Asus....i changed settings manually then...raised FSB to 350, with the RAM running at 700Mhz, relaxed its timings a bit as it is value ram 667Mhz, I fixed the vcore at 1.15V and Vdram to 1.8V, then my temps were 44C idle and 63C in load, the processor running at 2.45Ghz...now i want to know if these temps are normal? I have a generic casing, ATX with one fan at the backpanel thats it, i know exhaust is bad but still with the silent knight is this the best i can get? Plus i Just got it fixed yesterday, does the thermal paste of the silent knight need time? Please advise as I am worried about my upgrade....
I have also started a new thread with my query, so if somebody wants they can reply there, sorry for any inconvenience.
First post......stuff happens..then you die. So smile...enjoy...be happy and OVerclock like all get out !!!
And Thanks ...Thanks and Thanks
ok...I have system listed on profile. I use Probe II from Asus...most current version. When I overclock to 333 x 9 on my q6600...p5k mb...I get this measuring device on the Asus Probe II that shows fsb monitoring and it goes from a few Green squares up to RED!!!!! at just 333 x 9...I am in the next to top square. The system handles the overclock very well...its stable....and temps on loading are less than 50C constantly. Bottom line..do I need to worry about this FSB warning I am getting on Probe II????
Any help is appreciated and I Thank you in advance.
What TIM did you use? I used ARCTIC SILVER 5 and have a quad core....temps using OCCT for 1 hour with all cores doing 100 percent load never go over 52 C when at 3.0 GHZ overclock. I also use the newer Xigmatek HD xp-s964 cooler with the 92 MM stock fan. Runs great and have done NO modifying on Voltages etc. Just FSB to 333 x 9 multiplier and settings as per Cluncks forum here.
Good luck and I hope this is helpful to some degree. I also use coretemp to monitor the cpu cores along with asus probeII and Intel TAT.
Good Day
Is this forum dead???
Thanks
I hope this thread is still alive - I have a few questions:
Eventually got round to building my new system: Core 2 Quad Q6600 with P5K Premium WiFi (Black Pearl Edition) 2GB Corsair Ram 1066MHz and Thermalright 120 Ultra Xtreme cooler. (have not updated the bios so still on the initial 204 bios - don't know if that is part of the problem)
Problems are that it seems to be running a little hot: Currently overclocking to only 3.2GHz and when fully stressed reaches 62-63 degs C idle around 24 degs C Other than lowering the volts and FSB don't know how to get it running any cooler?
Also after 11 hours of Prime95 failed - core voltage is at 1.3 I do however have my ram running at its full speed of 1066 and not a 1:1 ratio so don't know if this is causing the error - Any suggestions?#
Thanks. eon
