Problems with Rampage Extreme and Cold

[[_Silence_]]

Hey guys,

This week I've received a Rampage Extreme to team up with my E8600. I've benched this E8600 on Biostar at 6400Mhzs (limited by my DDR2 that can only do 640/645Mhzs) and had cold bug at -160ºc.

Now on Rampage cold bug seems to be arround -90ºc. Air cooled the Rampage did 630 FSB for SuperPi and now with cold it doesn't even reach 600 FSB, with chipset at -20ºc +-.

Any ideias on why I'm getting this behavior?

Best regards,
Diogo

Update:

I'm able to run Pi at 650 FSB but with an high PL (15/16), gota work on that.

Regarding the coldbug, it's at -95ºc (on Biostar was at -160ºc, huge difference :S) and the chipset really hates cold, no go below 10ºc positive!

At this temperatures I can only bench and boot at 6100Mhzs more than this neither boots or runs anything if applied on Windows, really need more cold but the coldbug is killing me

Anyone that has tested Biostar and Rampage with the same E8600? Noticed this coldbug differences?

Regards,
Diogo

Well, when testing some E8600s on the RE I noticed often that I experienced a cold "boot" bug around -80 to -100 °C only few cpus were able to boot above -100 °C. In windows those -80°C cold boot bugs did something like -120 °C without any crashing. Annoying thing was everytime you powered off the mobo by changing some multiplier fsb or something like that in the bios u had to first cool down to -80 °C again to get it up running.
Other then that your problem sounds weird. I just used a delta to reach 646 fsb on the RE.

I'm going for air cooling on chipset again, it's enough for 650 FSB My biggest problem is the coldbug, no coldboot at all, just coldbug at -95ºc +-, 60ºc sooner than on Biostar

just stick to Biostar then hahaha

i have a cold boot bug on Gigabyte EP45T Extreme at -76C
but i can run benchmarks at -140C in windows no problems

as long as i don't touch bios settings i'm fine
