I have made a spreadsheet containing all of my details and benches of before overclocking and after, if anybody is interested:
http://www.sitalchauhan.pwp.blueyond...37;20Stats.xls
I will continue to update it with new benchmarks and fill in the missing gaps as I go along slowly :)
Ive had several boards that have had vdroop, in fact every Asus board that I can remember, but that doesnt usually mean that you cant get them stable.Quote:

The only thing left is the voltage settings (other than vcore and ram), if you can point me to what to try I will give it a whirl.Quote:

The only problem doing it like this, is that you need to keep an eye on it, and make sure that it doesnt rise too high when not under load.
If the voltage is up and down, I would return it, as that clearly isnt right.
Is there a noticable drop at stock voltages/speeds?
Yes and this is Asus reply is something to the effect that the Intel spec says voltage should drop proportionally to the load increase, the Asus forums are down, later I can post exactly comment from their FAQ. The vdroop is pretty dramatic. A google search on P5K vanilla and vdroop returns a lot of hits.Quote:

I was playing a game and got a bsod, pretty sure it was because I had overclocked my ram to 888MHz when it is only rated to 800MHz. So I changed my fsb:dram ratio again to 1:1.
I did another Orthos and this time got a bsod, even though last time it ran 12 hours no problem at the same settings. So I lowered my fsb from 370 to 360. I was getting a problem before where in Windows Vista, whenever I clicked on the Control Panel in the start menu, a window would flash up and instantly disappear. I though it was some kind of software problem with Windows. However, upon lowering my fsb, the control pannel started working again lol. Strange...
I increased my fsb back up, and sure enough the control pannel stopped working. Lowered my fsb again, and the control pannel worked again :)
So if anybody has a similar problem with the control pannel not opening, try lowering your fsb :p
Anyway, the max I could get my fsb while the control pannel was working was 365MHz.
I have updated my spreadsheet again with my new max overclock and updated all the benchmarks, temps, etc:
http://www.sitalchauhan.pwp.blueyond...37;20Stats.xls
Will be doing another Orthos tonight for another 12hrs just to be certain my overclock is fully stable.
Have you set the RAM voltage and timings to what the manufacturer says it should be?
All other settings as per the guide?
Yup ram settings and voltage are set as manufacturer's guidelines (2.2V and 4-4-4-12).
All other settings EXACTLY as the guide says. Followed it word for word :D
I am still very happy with this slightly lower overclock as my benchmarks hardly changed, only dropped a little amount. It is still a massive improvement over the stock settings :)
Yes, its according to spec:Quote:

Question
Both Asus and third-party utilities such as PcProbII/AISuite/CPUZ shows that my CPU Vcore reading drops as the CPU load goes up.
This also happens after I set CPU Vcore to a set value instead of the preset [AUTO]. Why does the motherboard act like this?
Will this effect the overall stability of my system?
Answer
As Intel specification clearly states Vcc (CPU Vcore) should drop in propotonal to the increase of Icc (CPU current consumption), in order to prevent causing permanent damage to your CPU. When CPU is under stress (in other words, under higher load), the current consumption of the CPU will go up, and the CPU Vcore will then drop to conpensate this change. This is a perfectly normal behaviour, and will not effect the overall stability of your system.
For more information, please refer to Intel CPU datashee, under "DC Voltage and Current Specification".
I dont really understand what that is saying.Quote:

Under load it drops quite a bit leading to instability.Quote:

Hi Clunk, just a quick question for you, I have this mobo with 404 bios, & C2D E6750, and I am able to boot up @ 3.6ghz (450x8) however I can't never success on running orthos for more than 1 hour. I already bumped up the voltage to 1.5v and my ram voltage to 2.3 and the ram is rated @ 5-5-5-15 @ 2.1V (PC2-6400)...I followed your guides closely and is there any additonal settings that I should focus on? besides running orthos, I can play games, watch movies, ripping dvd without any issues, but I still want to make sure my machine is 100% stable, and I also want to know what's the max voltage that this chip can take on? I don't want to screw my chip within a month..
Ok, first of all, 3.6Ghz, is around the top end of what most people end up using as their 24/7 overclock.Quote:

As always, there is no safe voltage, just keep an eye on the temps. If you need much more than what you are already using, its not going to be worth the tradeoff in heat generated for 24/7 use.
Clunk, the ram that I am using is Buffalo Firestix FSX800D2C-K2G 2GB 2X1GB PC2-6400 rated @ 5-5-5-15. I just serach online and this ram should be easily achrive 900mhz easily..Regards about the limit, I know that's pretty much the max limit for this chip unless I push it further, and the temperature from o/c chip is like 43c @ 100% (use Ezotech with 120MM fan), is that normal? I am running my C2D in vista, and i used at least 3 programs to monitor the temp, TAT, Speedfan & Asus Probe..Is that temp too low??
PS: My ram is running 1:1
Yes, that temp seems very low for that voltage. Dont forget that speedfan often reads 15c UNDER, and Asus probe is pretty much useless for CPU temps.
You may only be able to squeeze a tiny bit more out of the CPU, but it might need a lot of voltage, so why not drop the fsb a bit, get some reasonable voltage going, and then tweak the RAM?
I have a p5k deluxe with a cnps9500 at and a quad6600. My question is why is that my temp are so hot like each core is around 46 at idle.Also, i use arctic silver 5. Do i wait for it to settle down? i want it to be cool enough so i can start my overclock.I'm also new to this forum.
Clunk..I can't push further no matter how hard that I tried. Now I am 100% stable running my CPU @ 3.6ghz but the ram timings I can lower to 4-4-4-12 @ 450mhz (2.3V)..the Chip just can't go further, as you said the temp is little bit low, and I think even you add another 15 degrees on it, my temp is still under 65, so I think that will be fine..
Hi
I need some help with over clocking my new system, specs below:
Intel Dual Core E6850 + Scythe Ninja | Asus P5K Vanilla | 2GB Kingston HyperX ddr2 1066 | Sparkle 320mb 8800GTS | Antec Solo + Antec 550W
So far my best attempt is 420*9 (3780MHz) 1:1 ratio
Divider was set to 1:1
timings set manually 5-5-5-15 (as per the ram vendor specs)
now i'm trying to see how far fast I can run my RAM so I can possibly run a lower multi (8x) and 1:1 with my ram at decent speed.
My biggest issue at the moment is the ram, I’ve set the multiplier to 6 manually and the ram will not go over 900mhz at 2.3v. It’s rated for 1066@2.2v ???
any ideas - it’s been a while since I looked at this sort of stuff and I’m not used to the bios on this board. Should I look at the Northbridge voltage?
I tried all the settings you recommended in Step One but still cannot get this board/mem stable with anything above fsb450. And by the way at 450 its 2hrs+ otheros blend stable but at 455 it doesn't last 30 seconds
You havent said what cooling, or even what your load temps are.Quote:

I really need a new computer, I have no idea why my post keeps on going in completely random threads....
Well i have the zalman 9500 cooler and i haven't tried running a full load because over here is really hot.
at full load the temperature is 61 61 59 58.
Assuming you have a sensible amount of cooling through the case, have you thought to check that the Zalman is contacting the the CPU fully?Quote:

Then you need to find out why, possibly lap your heat sink (polish it till its flat) and also, don't use loads of Thermal paste that will make it worse.
In your experience, in a water cooling setup how much of a difference does having 3x120mm fans blowing on a radiator have on cpu temperatures? Reason I ask is (at idle) I disconnected the fans and the temperatures remained exactly the same. Not tried it at load as i'm heavilly overclocked (well to 3.25GHz)...
A lot.Quote:

Some rads perform better with high cfm/speed fans, and some perform well with low cfm/speed fans.
Cool :) (No pun intended!)
I'm still testing my overclock potential and can get it up to 3.4GHz, but would you be happy/comfortable/worried if the temperatures are 70-70-68-68 with 100% load on each core (measured with coretemp, stressed with 4xSP2004 on stress cpu test)
Can you put your system specs in your "My System" bit please, with all the info about the cooling etc :)
Sorry mate didnt realise i still had my old pc in there :) Check now
Just to let you know that I am running my e6600 at 3.30GHz at 1.45V. My idle temps are 31 degrees, and load 67 degrees (using TAT to stress the cpu, coretemp to measure temps) on air using a Thermalright Ultra-120 eXtreme. I have been running this overclock 24/7 and am fully stable with no problems whatsoever. I think 70 degrees is the upper limit to what you should be running 24/7. But I am having no problems running at my temps. I would only really be worried if my temps went above 70 degrees.Quote:

awesome guide
oh and thanks
This is my first OC and I am following Clunk’s excellent Guide. Just beginning to OC my E6850 to 3.8GHz. However, please comment on my screenshot:
[Sorry. Cannot post URLs yet].
img486.imageshack.us/my.php?image=tempjh7.jpg
[1.4625 Vcore in BIOS, RAM 2.05V, all other voltages AUTO]
As you can see, anywhere after 2-8 hrs of stable Orthos, my CPU temp suddenly spikes to nearly 100C (even hit 120C) [Probe II Log]. The temperature never drops much afterwards, even if Orthos stopped (as the screenshot shows) Yet, Cores are usually around 50C during Orthos runs (TAT, CpuFAN, Coretemp .95, Everest - all agree).
1. What’s going on?
2. What software for temp monitoring should I use? [After restart, my CPU temp is back to 30-40c with all the software].
3. Somehow my CPU temp is always higher than my Core Temps? Is this normal?
4. Do you consider this ok for 24/7 use? [Core Temps 48-51 under load, CPU temp 65 until it suddenly spikes].
5. If I give the chip more Vcore (like 1.48 or even 1.50), is the risk of OC limited to the chip? OR is it likely that I may damage MB, Ram, Video Card?
6. Does the Vcore requirement differ from 9 x 422FSB v. 8 x 475FSB?
Looking forward to your advice!
Specs: E6850 with Ultra Extreme (Scythe 1600RPM & AS5) | Asus P5K Deluxe (0404) | Mushkin 2x2GB DDR2-800 CL5-4-4-12 (Micron D9GSV) @2.05V (Rated 2-2.2V) | OCZ 8800GTX | Corsair 620W | Lian Li PC-A16B
Well I did reapply arctic silver 5 and remount my HSF. Now the temps are 47 46 44 46. on idle. don't know about load though. My vcore is 1.200v at 2.4ghz.

Dont forget youll need mega cooling as well if you want to overclock it :)
Yeah.. I wonder if my asetek kit is up to job? I'm cooling the 8800 and the cpu only with a twin rad..
is it a twin 120? if so it'll be insufficient for cooling both the 8800 and an overclocked quad. if you're overclocking the 8800, put it on the 120.2 and get another pa120.2 for the cpu, or if you're running chipset+fets, a pa120.3 :)
And dont forget youll need a different CPU block as well. The cooling area on the single/dual core blocks is much smaller. You can still use them, but you wont be getting the best out of it.
As Steve says, a 120.2 probably wont cut it for an overclocked quad and an 8800 (GTX is it?)
Overclocked quad = anything up to 250w of heat (say 3600 with 1.6v ish for arguments sake)
Overclocked GTX = Around 200w.
So, assuming that you arent going to be cooling the chipset, thats 450w of heat you need to get rid of, and a 120.2 isnt going to do that, even with huge cfm fans.
:)
Did you actually look to see what sort of contact was being made?Quote:

well just been tweaking a bit with clunks guide, and so far my 6750 has hit 3.36Ghz (and thats just raising the fsb a bit) and been running orthos for like nearly 2 1/2 hours with no probs
http://img2.putfile.com/thumb/8/21418423581.jpg
I did look at the cpu and the contact is pretty good the temp vary from 1 or 2 celcius from each other especially the third core, the rest post the same temp. I think it is because of the temp out side is around 32 something and my room is probable more since it is not air conditioned.Also having a vcore which lower than 1.325 suppose to be cooler?
Getting there mate :)Quote:

If I try to give it more voltage, the HDD failed to load and my windows is corrupted :S
BUT, I can run the stick with no problems at full speed (1066) with vdimm to auto in channel A2 and B2.
is it normal ?
I'm thinking we need to give clunk his own overclocking sub-forum :D
If I remember, the first pair of slots you mention, are the YELLOW slots (which is what the manual suggests you put them in) and what I have mine in.Quote:

Yes, black slots for 2x1GB on the P5K boards.
Make sure you have correctly entered the RAM voltage and timings.
You could also have a bad stick of RAM, so it is worth testing with memtest v1.70, test 5 for at least an hour on each stick individually, and also do the test with each stick in all the different slots.
Here are some images of the EK blocks on the P5K. Please note that the Southbridge needs modifying to fit around two near by capacitors.

http://i204.photobucket.com/albums/b...IMG_0665-1.jpg
sorry to h/j your thread again clunk but I did the tests you mentionned and I'll need a little help to figure out if it's my memory or my board that is defected ..
all the test were done with memtest 1.7.
at 800 mhz, both stick of memory passed all tests in all slots in single and dual channel mode.
for 1066mhz,
stick #1 (single channel) : slot A1 post, but I get 1000000 errors in test #5
stick #1 (single channel) : slot A2 post, all tests ok.
stick #1 (single channel) : slot B1 don,t post.
stick #1 (single channel) : slot B2 post, but 122 errors in test #5
stick #2 (single channel) : slot A1 don't post
stick #2 (single channel) : slot A2 post, all tests ok.
stick #2 (single channel) : slot B1 don,t post.
stick #2 (single channel) : slot B2 post, all tests ok.
The best I can run my memory in slot A1 and B1 without error is 900 mhz.
I tried to set the vdimm manualy, to relaxed the timing, but it didn't helped. Now my question is, if the memory is defected, why it's working correctly in channel 2 ? But if it's the board, why at 800mhz everything is ok ?
Thanks everyone for all the input, your help is very appreciate.
Can you just confirm that you set the memory voltage (VDIMM) manually?Quote:

The best I could get in slot A1 and B1 was 900mhz on my 1066mhz rated DDR2. From what I understand, it could be a chipset limitation because asus says they officialy support up to DDR2 800 and throught O/C, they support up to 1066mhz ..
I'm confused a lot :S
Dont be confused, its bad for your health :)Quote:

The black one are working perfectly (even at auto), but the yellow are just not working ..
how is it possible ?
I tried to relax the timing, I tried 1 stick at a time. The computer won't even post :(
btw I have the P5KC board, maybe that\'s why :S
OK, did you read the troubleshooting guide thing? That explains about it really being PC2-6400.Quote:

You will find that if you were to add another 2x1GB to the yellow slots as well, they would work fine. Its just a quirk.
So, to recap, dont use the yellow slots.
thanks clunk,
yes I read the troubleshooting guide and I understand about the ram being PC2-6400.
my main fear was if I wanted to add another 2x1gb PC2-8500 to the yellow one they wouldn't work as expected.
I'll let the ram in the black slot since they are working good in them.
Thanks for your help.
Nah, works fine with 4x1Giggleybites.
while I'm at it, I thought of something last night. At first, my PC2-8500 was working in the yellow slot, before I did the bios update.
I did it, because I wasn't able to o/c my cpu and thought it was the bios, but it was just the intel thing in the bios :S (my bad)
now if I try to downgrade to the original, the Asus EZ-Flash won't let me .. any other way I could do that ? (I searched, but found nothing, even on google :S)
Thanks for your time
Thats strange, I managed to downgrade my BIOS without any problem using EZ-Flash. I just put the older bios onto my usb stick, pressed Alt+F2 on boot to load the Asus BIOS flashing program, and downgraded my BIOS without any issues.
I have questions!
How do I change the RAM voltage on a P5K-e?
My memory timings are slightly wrong, am I safe to just switch it to manual and set them myself, or do I need to make any other modifications?
The Asus utility reports motherboard temps of 40-45c. That seems high. Should I be worried?
The P5K-E has the same bios as the PK5 so just adjust the dram voltage set to manual and just the timings and use memtest just to be sure that the ram is able to run at those timings. Use coretemp to measure your cpu temps because its more accurate.Quote:

Yes, you should manually enter the timings, or itll default to the SPD.
See this post for info about your motherboard temps.
because I can't get out of my head why the yellow can't run 2x1 .. why they were made then ? :eek:Quote:

Please help me stabilaze my comp!
I've overclocked Q6600 to 3,6Ghz (9x400)on air cooling. But Prime test crashes after 20 minutes.
Motherboard: ASUS P5K Premium
RAM: CORSAIR TWIN2X2048-6400C3DF 2GB(2x1GB) FSB:RAM = 1:1
COOLLER: ZALMAN 9700LED
Video: ASUS X1950XTX
Vcore is set to 1.5. On Prime test heats up to 63C. But in EVEREST ULTIMATE test goes higher then 70C.
If i reduce Vcore Prime runs crashes even earlear. Althou if i set fsb to 390, Prime runs more then an our with vcore set to 1.4. Can 100Mhz really bring such a huge unstability?
Or maby it's because of overheating?
What was the last stable overclock before this one?
And what temp does coretemp say you have under load?
FSB = 390MhzQuote:

Right, well, its pretty certain that you are right on the limit of what your CPU will do without a lot of voltage, and its a pretty good overclock for air cooling.
Try coretemp, You might find that its around 15c higher than speedflange.
I quess 75 for cores is critical isn't it?Quote:

Core temp shows 75C in cores Just like EVEREST Ultimate.
I've decided to run prime once again and it didn't crash for a 1.5hours.
So i continued with ram oc. I've plugged memory chips into black slots.
Perfomance increesed quite noticably(1000Mhz; 4-4-4-12; Vdimm-2.3)..
Black slots:
Read 9231 MB/s
Write 7271 MB/s
Copy 7901 MB/s
Yellow/Black slots (1channel)
Read 7700 MB/s
Write 7270 MB/s
Copy 6605 MB/s
But under 100% load CPU temps rised up to 70-75C with the same vcore and fsb options.
I haven't tried yellow slots yet. But i'll let you know about the results.
And another thing. Corsair TWIN2048CL3DF goes with a fun. and if this fun is plugged into the MB
prime works less then a minute and system restarts. Without the fun - prime acts as usuall.
What do you think about that?
Yes, it is well documented (see the previous page, and the top of this page) that the yellow slots can cause errors when used with 2x1GB. Always use the black slots. It is fine to use the yellow slots if you are using 4x1GB.
Fun=fan? If so, always use it or your RAM will die pretty quickly, especially with 2.3v through it.
Have a read of my guides and the P5K thread, all this info is in there :)
Yes Fun=fan :) sorry for that. But why does CPU temps raise to 75C from 65C on black slots?Quote:

No Idea why the temps would be different, I suspect it would be the ambient temps that are changing.
You need a fan that is fairly close to the RAM, expecially if it is higher voltage RAM.
Are you trying to connect the fan to the motherboard headers? If so, it might draw too much current, try it on the main loom, or get a fan controller.
Yes, i was connecting it to the motherboard. I'll try something else...Quote:

Thanks, Clunk!
This is my first time overclocking and wondered if you can help.
I'm using the P5K-E board with the latest bios set to it default and a Q6600 processor.
When I run CPU-Z the Multiplier shows 6, I thought this was supposed to be 9.
The other settings it shows are:
Clock 1860.2
Multiplier x6
Bus Speed 310.0 mhz
Rated fsb 1240.0 mhz
Can somebody please point me in the right direct to over clock this processor.
I did try changed the FSB frequency in the bios to 310 and setting the multiplier to 9 but still cpu-z showed me a multiplier of 6.
Many thanks,
Dave.
Click the troubleshooting guide in my sig, number 9.
Also, read the guide, its all in there.
Thank you Clunk,
I shall go and read.
Regards,
DAve.
Hmm, tried the obvious fro your FAQ item number 9 but it still shows x6.
Sometimes it jumpts to x9.
I went back into bios loaded all factory defaults then disabled the speedstep again, rebooted.
Showed x6 still.
Went back into bios and set the multiplier to x9 back in windows shows x6 arhhh.
It is as thou windows has a speedstep of its own.
Sorted it.
I missed one of your settings, thankyou.
Which one did you miss?
thats a good question, I will go through it again.
Sorry I run a shop (computer shop) and its manic at the moment runing backwards and forwards.
I guess it was C1E Support, that drops multiplier, when a processor is idle.. if you say, that it jumped to 9 and then back, then this is the only reason...Quote:

The problem is that I cant get the mobo to boot in DDR2-1066 !? (all settings Auto, it boots the memory in 800Mhz)
I have set the DRAM frequency to DDR2-1067
DRAM timings 5-5-5-15
DRAM voltage to 2.2V
everything else is Auto
After POST I get info that I have a incompatible CPU, press F1 to resume...
Any tips ?? what settings should I have ???
