i7 960 @4ghz Semi-stable - Page 2

post #11 of 26
1.4V is above the max recommended voltage and can having your QPI too high or too low can cause instability.

Same CPU Voltage

QPI at auto : failed in 6 minutes
QPI 1.3v : failed in 3 minutes

Should I just set QPI at auto right now and focus on CPU Voltage or do someting else ?

Adjust your BClock to 200 . Adjust the multiplier to 20. Step your CPU voltage to 1.375. Reading this out of the BIOS wink.gif i7 920 Asus p6t6ws revolution .

I would not suggest using the 20 multiplier even multipliers usually only give trouble. I would try 1.35 for the QPI also what where your BSOD codes.

I can't seem to find the link to intel's list of max voltages, but the VID Voltage Range 0.800V-1.375V doesn't refer to safe voltages, just to what it can set itself to, IIRC.

I got it from this guide LINK.
While the VID range is only for what the CPU can be set to for previous CPUs going to much above the max range will kill some of them. The generally accepted max cpu core voltage for 24/7 is 1.4-1.42.

I dont BSOD.

If you are just freezing or prime 95 is giving errors up the core voltage by 2 notches and try again. Also check out the guide that I linked to it can help a lot.

I am increasing the CORE Voltage right now each time the large fft test fails. Will post results later. Thank you all so far. smile.gif

edit : I read that guide so many times that I memorized the voltage values tongue.gif

For reference:
http://www.intel.com/content/dam/www/public/us/en/documents/datasheets/core-i7-900-ee-and-desktop-processor-series-datasheet-vol-1.pdf
Absolute maximum voltage is listed as 1.55V

And while I may need 1.4V to run mine @ 4.0, it is a c0/c1 (according to cpuz), so that seems par for the course, and it's both prime and OCCT (linpack) stable, so I'm pretty pleased with it.
