bah!! me too.. ,
stable at 7x400, bios 1.18v
but when try 8x400.. bios put 1.25v also cannot stable..
cannot try higher liao.. too hot >_<

Don't worry la.... My Q6600 need 1.400v in BIOS to run at 8x400....

Bro kmarc, got a question here. I've been running stable at 3.2ghz (400x8) on my Q6600. However sometimes, when starting the pc, it jumps back to stock clock, why did this happen??

How did you test for stability? Recommended to stress your rig using orthos or prime95 for at least 6-12 hours....

It is possible that your mobo reset to stock settings due to instability........

Possible you set the cie n eist enable on your bios setting.

yup. Is that the reason? Thanks.

dang, tried crank vcore to 1.2375@bios ... stress it,
cpu : 63c/58c (coretemp/realtemp)
nb : 52c (everest)

cpu & nb differs only 6c .... wtf!

thats because its 4mb x 2.





put a fan on the nb, use rubberbands or zipties

stress test stable for 2+ hours with 333x9 1.28vcore.
need to stop the stress coz need to use the pc to burn dvd.

Nice. OC higher!

Why are you using 4 instances of orthos? Download the new version of Prime95. The app stresses all 4 cores simulateneously..... no hassle of starting 4 orthos and setting core affinities....

Keep the temperature around 60-65'c though...

Nice OC, I'm sure your able to go higher since your using a G0 Stepping proc, bump up the FSB and Vcore ....what HSF are you using? Are you able to change the GTL settings using your MARS mobo?

One quick ques. One of my CPU core(out of 4) failed during prime95. Is it consider stable?

Quick answer - nope. Not stable....

Wow...Quick Que & Ans

-pWs-

I just want to share my oc experience.
I'm having hard time to overclock my Q6600 with asus p5n32-e sli
(1203 bios) manage to get 3GHz @ stock voltage stable.
my fsb seems limiting my proc oc'bility. change to x8 multiplier,
i manage to get 353 FSB stable. I'm aware that p5n32-e sli is poor overclocker on quads.

Then?

The only way to increase the overclockability of your Q6600 on that P5N32-E SLi board is to do the Rev. A1 mod.
And by doing that, you'll void the warranty of your board.

LOL thanks for the tip. I knew that too.

The Asus P5N32-E SLI, absolutely hates quad cores, contemplated on doing the mods to be able to modify the GTL voltages, someone from XtremeSystems forum did this mod, but finally just too darn lazy, sell the darn mobo and get something more quad core friendly...

yeap. keepin it well below 65C

hey, long time no see Burger.
using BTVX atm. nope, doesnt hv GTL settings to play with.

This guy overclock Q6600 heavily on P5N32-E SLI. Any idea?
