*Official Retail G0 Q6600 Overclocking Thread*

[chuckbam]

I am slightly confused - what speed are you trying to get the q6600 to run at for 24/7 operation. I will happily run mine 24/7 @3.6 without any power management as it only idles at 34c. Sure it increases under application/game load but nothing like running prime95 all day. As long as you have decent CPU HSF and a good airflow through the case it will be fine. What HSF have you got as 50c is a bit high with nothing running and underclocked.I would expect it to be somewhere between 30-40 on idle allowing for different batches.
Why you want to buy 32 bit vista when you have Vistax64 - you have a 64bit CPu and vista x64 runs fine. Seems a bit of a waste.
CPU PLL voltage is a BIOS setting on the P5K which I understand to be for fine-tuning the power supply of the q6600. Increasing the default setting can help stability of o/c with high fsb.

sesdave,

I am just trying to have a balance of performance/stability. My power management only changes the multiplier not the Vcore. Are you saying that running Prime95 all day is to high a standard?

The temps at 50c are the core temps. Is the the Intel Thermal specification of 71°C the CPU temp? I read on an Intel PDF that on a 775 you have to have the sencer mounted directly in the center of the die. My CPU temp in that pic I believe was in the high 30s. But, on average it is less (See the pics)

I have an ARCTIC COOLING Freezer 7 Pro with 3 day old Arctic Silver 5 (different companies).

After many re-installs, I just dumped a Asus VR-Guard cooler. It was just a big hot hunk of copper. I even added a additional fan and it helped only a little. I put the OEM fan back on and then went to what I have now and this is the best out of the three. The min temps are not the best, but, the max temps are fairly low compared to the other two. I don't think I have a CPU cooling problem at high load for what I am trying to do.

Before that I dumped CORSAIR XMS2 8500cs DDR. It did not run anything close to the claims on my board. I replaced it with what I have now and I have better stability, mem speed and timings. This mem is on the QVL list.
I can believe how much DDR2 went down in price in 3/4 of a year. And the DDR3 prices are way out of site. I bet they will go down substantially in the months to come.

I would not install Vista Basic 32-bit. I believe I have seen the OEM Basic 64-bit at Directron.com. Also, I have installed Basic 64-bit on 2 computers with the Windows 64-bit Anytime Upgrade disk and a Basic 32 valid OEM key. I want it to read 4 GBs of memory.

I Vista install I have now is not setup for any Benchmarking. I have been running Prime95 though for probably 1/2 hour and all is good.

I picked a Vcore of 1.42 and that is as high as I will go. That should be safe for long term use (yes, no ?) I am at 8x 430 3440 MHz. 1:1 860 mem.

FSB of 450, I had a BSD at boot, FSB 440 I ran Prime95 for around 20 min and had a re-boot.

Now I am at 430 and all is good. If I need to go lower, I am just going back to the 360 9x and stay at that. You can tell by my Video card that I am not a gamer. But, I am a big time multi tasker. Vista feels real go with this 4 core CPU. I really notice a difference.

I would like to find a way to OC a ATI vid card in 2D. Just a little


Here are more temps at 1.41-1.42v.
