Cheers for the guide, I have one of those Pentium named dual cores on the way and hopefully can clock it at least a ghz =]
Ive got a P5K-VM, ive overclocked my e6300 from 1.86 to 3.0Ghz by 428 FSB and 7 Multiplier, I read this guide as well, very nice, though my ram was kingston value ram at 667, its running now at 856Mhz with 1.9V, but relaxed timings , the system outperforms the core2extreme x6800 in benchmarks by quite a bit, so I guess its all good.
It's been a good long read, and now It's my turn to post. First of all, as listed in my system, that is my overclock under Vista 32 bit. Here is how I have set up my Bios:

I have had it overclocked higher: E6700 @ 425mhz @ 3400mhz @ 1.4v/ Crucial @ 1063mhz @ 4-4-4-8 but it proved to be unstable. Ultimately I want to get an overclock of a multiplier of 6x 533mhz so I can run my Ram at 1:1 @ 1066mhz According to the X-Bit article it should be possible.
And finally, I know Clunk has always said to use the black sockets for the ram to run a single "dual-channel" but the manual(page 2-14) indicates dimm A1, and dimm B1 are the recommended sockets, and they are yellow.
Any comments would be welcomed
Thank you
Hi, thanks for the guide.
I'm on a P5KC with an E2160.
How exactly can i get this 1:1 to work?
EDIT:
Nm, sorted :)
Clunk is not as smart as he thinks he is , I would advise all who reads this thread to cross reference other resources as well before attempting an overclock.
I'm sorry if the beginners guide was too difficult for you.
If you click here, and go to number 8 on the list, you'll see that it does indeed say that the black slots work best for me, but then it also says "your mileage may vary", which to me means that you may have to try putting your two sticks of RAM in the other two slots if you are having trouble with the black ones.
I would also advise people to cross reference other aticles, especially if they aren't too good at reading and absorbing a single article and then putting it into practice.
That is assuming that I think that I am smart. You don't know me, or what I think my own intelligence level is.
Regarding your quest to get 533x6 to match your RAM at 1:1, from that I can conclude that I think that you aren't smart enough to question my smartness.
I hope that smarts a bit. :D

Good guide.. but does it apply to all P5Ks or just the Wifi deluxe first mentioned? Are the BIOS settings consistent through out the range? I notice Scan sell NINE models
Asus P5K Premium/WiFi-AP
Asus P5K SE
Asus P5K
Asus P5K3 Deluxe/WIFI-AP inc Ram
Asus P5K3 Deluxe/WiFi-AP
Asus P5K64 WS
Asus P5KC
Asus P5K-E/WIFI-AP
Asus P5KR
Personally I would be looking at plain Jane P5K (still with copper cooled northbridge and Raid but not so many ports as P5KR). Nowhere can I find confirmation of the BIOS OC options of this model compared to others.
It was written for the P5K deluxe WiFi AP almost a year ago.
There are obviously going to be settings in the Deluxe BIOS that aren't in the others, but as this was only meant to be an easy walkthrough to get people up and running, and no-one else contributed any BIOS shots at the time, its all for the P5K Deluxe WiFi AP :)
Hi there Clunk!
Thank you for the beginners Guide you have provided an excellent guide.:clapping:
Have recommended your guide to others after i have used it for my Asus P5K-E Wifi-AP.:)
Since this guide is 12 Months old & there has been Bios updates changing some options in the Bios such as Load calibration & some others that i cant think off.
Is there a Version 2 in pipeline somewhere with a little more involvement in more tweaking in the Bios.
Still unsure of some choices & what they do..lots of these are set by you on Auto in the Guide....such as Cpu voltage reference 0.63xetc?.
North Bridge Voltage reference 0.67x?.
I suppose i am asking for a more advanced guide or maybe just some of the new bios options what they are & what you would recommend. :bowdown:
Keep up the good work thanks inylbt23
I can't get mine going at 9X411 around 3.71Ghz
I can only go until 3.61Ghz (9X400)
I have the following:
1) X800XL vid card
2) Q6600 G0
3) OCZ Gold XTC PC2-6400 (4 X 1Gb per stick of dual shared RAM)
4) Asus P5K Premium
5) 650W
6) Custom Water Cooling
Here are some pix of the numbers I am getting:

Can I have one?
yup...but only after the man up there...he deserves one. :)
does anyone have ASUS P5K PREMIUM/WIFI-AP?
there is a new BIOS ver.0504 maybe someone has tried it?
Is it stable with OCed Q6600?
HI,
I did not finish reading your OC post, but I was wondering if this will also apply to my mobo:
P5W DH Deluxe with Q6600. :(
Looks very similar to the P5K model. I just want to make sure prior to start OC my system.
thanks for your inputs!

Hi!
A question about RAM overclocking. In the guide, there is a Sandra screenshot showing about 2% improvement after tweaking, but in the text it says some real world applications have greater benefit.
Which real world applications are those ? How much is the performance improvement ?
Thanks,
David
I have a P5K-E/Wifi and an EVGA 8800GTS G92 512MB card. For some reason, overclocked or not, the system will not recognize the video card. Sometimes I will get the video card not detected error code. Once I do get it to boot, it runs fine as long as I never turn it off. With any other video card, I never see this problem. Yes I have replaced the 8800GTS, tried diff RAM and replaced about every component trying to track the issue down. I have also tried various BIOS flavors. Does anyone know if there is an incompatibility between these? Maybe because the 8800GTS is PCI-e 2.0?
Hello folks, my first post here.
I'd like to thank Clunk for making this guide. I had wanted to get my Q6600 to 3GHz as my goal and using Clunk's guide, I now know that my CPU is capable of doing 3GHz easily.
I havent tried over 3GHz because...
My Thermaltake Big Typhoon v1 cannot handle the thermal load the Q6600 does :mrgreen::mrgreen::mrgreen::mrgreen:
I watched in SpeedFan as my temps rose to 65 degrees Celsius under OCCT load :eek::eek::eek::eek::eek: then I knew I shouldn't even attempt any more further.
So thus I brought everything back to stock.
Now question is: Which CPU cooler is the best that can handle the Q6600 being OC'ed to 3GHz?
I use the Zalman 9500. It's easier to fit in most cases and provides excellent cooling. Just dispose of the fan adjuster and hook it directly to the mobo, as you might as well run it full speed. Even at full speed it's a very quiet fan and my system stays at about 43C under load. (I overclock to 3.6GHz on my Q6600/G0, currently.)
Hello all,
This is my first post and also the first day of overclocking a CPU.
I got a q6600 (b3) currently running @ 2.7 Ghz (9x300fsb) With temps at load 75 (average: core 0 & 1 @ 79 C and core 2 & 3 @ 72 C) with stock fan on an Asus p5k.
I use OCCT as torture test and the temps are from Speedfan. With Prime 95 the temps are a bit lower, 71-75 C.
The system has 1 intake fan and 2 outtake fan's.
When the system is running at stock speeds the max temp is 68 C.
Are these temps acceptabel?
Well, while I'm using a G0 @ 3.6GHz (9x400), not a B3, those temps seem pretty high. I'd recommend removing and reseating the heatsink with some good thermal compound and see what happens. I would consider my last reseating of the heatsink to be fairly good (I've done better, but my hand slipped a bit while setting it down) with Arctic Silver, and I'm getting 34C System, 28C Core1 with no load, and under load it goes up to around 38C on a cool day, 42C on a warmer one.
Nice temps, I got It clocked @ 3.01 Ghz Now. max load for core =83 C
Full Load temps (prime 95 & speedfan)
system=48 C
Cpu = 69 C
Core 0 & 1 are both 83 C
core 2 & 3 are both 79 C
Idle temps
system = 48 C
Cpu = 47 C
Core 0 & 1 = 58 C
core 2 & 3 = 54
I often use this PC for gaming and it never gets 100% load. As for yesterday I played Company of Heroes (cpu intensive) which runs at the first 2 cores only and get an average of 66 C. ( this was on 2.7 Ghz) and 71 C @ 3.0 Ghz
But I think I let it @ stock speeds, I just tested what a B3 is capable off. only think I notices that if you overclock 100 mhz at a time the max temp only rises about 3-4 degres. stock max load = 68 C, @ 3.0 Ghz max load = 83 C
I would call those temps high, but not unreasonable. Did you try reseating the heatsink with some new thermal compound yet? Even with the stock fan (which I personally dislike very much), I think you can get it a bit cooler. If you were willing to invest in a Zalman 9500, I would guess that your temps would drop 20-25C easily. There is a night and day difference between a full copper, well designed heatsink and the stock ones that ship with the Intel chips.
I've just cleaned the computer, and made it dust free. The idle temps dropped pretty much.
This is on stock speeds because the temp when overclocked is to high.
Idle:
CPU =38 c
core 0=48
core 1=48
core 2=44
core 3=45
Load (with OCCT)
CPU =55
core 1=67
core 2=67
core 3=62
core 4=62
Hi all
Nice guide, very easy 2 follow ,in fact 4 the first time I`m beginning 2 understand how things work in a pc.Big thanks 2 Clunk.
First my specs. C2D E6750 2.6Ghz /P5K-SE / 2x1G KingMax 1066 DDR2/ nVidea 8600 GT / Samsung sata II / xp sp 2.
Ok so 4 me, games put the heaviest load on my pc,as 4 other apps I rarely do encoding, archiving and so on.
So I follow the guide, put everything on manual under clock to 1.8Ghz ,fsb 300/multi. x6, ram 600mhz, nice 1:1 ratio in Cpu Z right? and go wild benchmarking.
STALKER using fraps I got 17 to 22 fps
Fear Perseus Mandate -performance test -min27/ averege52 / max 108 fps 64%over40fps
Crysis cpu benchmark 2 - 18 fps
Ok so I go 2 bios change fsb 400 ,multi: x8 , ram changes to 800 , CPU Z reports 3.2Ghz ,1:1 ratio ,ram 400 and of course I go benchmarking.
STALKER same settings,same map, using fraps 17 to 24 fps
Fear PM -same test/ settings - min31 / averege54 / max108 / 70% over 40 fps
Crysis cpu benchmark 2 -20 fps
My conclusion ,at least 4 gaming I see almost no difference and I`m pretty sure the vast majority uses comps mainly 4 gaming.So should I invest in cooling? but why?
On the other hand this guide was very informative 4 me . Thank you.
Overclocking a cpu will increase you're performance in games, however you will only see big performance differences if you got a fast gpu in games. Crysis is optimized for multi threading. But the cpu is often "waiting" for the gpu to render. The more fps you get the faster a cpu must work.
For an example: An 8800 GTX requires a dual core 3.0 Ghz to work at maximum speed. Now think about putting 2 9800 GX2 in sli with a dual core 3.0 Ghz and you can see that overclocking the cpu will have great performance increases.
Try an other application to test performance. You might want to run pcmark at standard speeds and then at overclocked speeds. Or just unzipping/unrarring a Large file.
Hi!
Could I ask P5K owners to check my problem in thread : Slower concurrent disk access with NCQ ? ? (sorry for spamming, but only other users can help me; respond in that thread, to keep this one "clean")
Thanks!
new to this lot myself
just put together a p5k Ai lifestyle mobo with q6600 quad core cpu, 2x1gb corsair ddr2 800mhz pc2 6400 cl(4-4-4-12)mem, geforce 8600gt 512mem, with Artic Cooler Freezer pro +2x120mm fans and seagate 250gb HD
Now the hard bit, dont have a clue what the mobo setting should be, all on default settings,apart from the mem i changed that as it was set at 5-5-5-18 clocks would like to get the cpu up to 3ghz if poss but dont know how..ant help would be most welcome have got pics from cpu-z but dont know how to upload them onto here
start with basic front side bus increases m8, check clunks overclocking thread, its worth its weight in gold :)
Hey guys anyone ever recieve wierd Asus Pc Probe readings for their motherboards? im getting 171 degree celcius with only a 3.4ghz oc and 1.45v vcore 2.2v for mem
Thanks
Hello,
I have strange problem:
I don't see any overclocking options on my BIOS v02.61 American Megatrends ( like Jumperfree configuration).
How can i unhide them?
Thanks!
hello guys
i have a pk5 se with the e6750 and 2 rams at 800mhz i just wanted to ask if my rams are responsible for cant overclock my pc over 400mhz.is tha normal?when the speed of the rams exced 800 mhz the pc freezes i put the fsb at 350mhz and the rams to run at 815 mhz and it freezes again and i think its the rams.they cant run more than 800mhz.what do you think?should i get rams with more mhz??thanks :)
Curious, what is the dram command rate? What should that be put at?
Clunk
have just started using your guide today after weeks of deliberation and putting off overclocking. Thankyou very much for all the work put into the guide.
My q6600 is running at 3.33ghz now as i run stress tests and im feeling alot better about trying out further tests now
thanks again
You ever figure this out? I've got the same problem.
Given the last post on this thread, which itself started in 2007, was well over 7 years ago, I doubt you're going to get much joy. It also doesn't help that you don't quote the specific problem you mean - this is a 600+ post thread, so I suspect there are a few problems mentioned!
If you have a specific problem, I recommend starting a new thread and giving proper details so our knowledgeable community can assist you. :)
