*Official Retail G0 Q6600 Overclocking Thread*

[sesdave]

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)

One 24hr run of prime 95 is more than enough to prove any system stability for MB,CPU and memory- it maxes the machine out way more than any normal use of multitasking will do. I have never bothered with more than a 12hour run but some forums demand it to prove your overclock. Depend on how keen you are - although as you want 24/7 use it worth doing.

Coretemps are what count. Here is a link to an article re tcase,tjunction and all thing temperature for CPU's http://www.tomshardware.co.uk/forum/...perature-guide
Your idle temps seem high -Whats your case cooling like. I had an arctic cooler 7 pro before the ultima-90 and it would idle 37c @3.6 with 1.425v using MX-2 paste. If the load temps of 60c are with prime95 running that looks good to me.

Dont give up on 440 just yet - uses other BIOS options than vcore to try and get stability. I use not only CPU PLL increase for stability . This is an interesting thread on how CPU Voltage Reference & NB Voltage Reference can influence OC- ability. http://www.xtremesystems.org/forums/....php?p=2461613 What make is your memory and what volts are you giving it. You could try loosening the timings to 5,5,5,15 first to get the system stable and work on it later.

Rivatuner is the tool I use for overclocking my 8800GTS - it has a 2D/3D option. Get it from guru3d.com. http://downloads.guru3d.com/download.php?det=163 good site for most drivers and tools.

Dear sesdave,
Thanks for all the links and other information. I read them all.

I am using Kingston HyperX DDR2 4GB, HX6400D2LLK2/2G, Specs PC2-6400 CL4 +2.0V. I can run this memory at about 455 @ 1.25v -4-5-5-12.

I have decided that a 9x 360 OC is the best overclock for me. I considered both 3.24 and 3.44. I found that with (P5B-D) my motherboard, gaining the extra .20 GHz was just not worth taking this CPU out of Vcore specs.

I think I am getting the performance I need. I will have to see what others are testing at.
