First my setup:
ASUS P6T mobo with latest BIOS version
Core i7 920 (C0 stepping) cpu with Scythe Mugen II cooler
ASUS GTX275 graphics card
Tri-channel (3x 2 Gb) 6 Gb memory, 1600 Mhz
Running on W7 64 bit (7600 RTM)
So, when my BIOS is at default settings, my pc is stable. But as soon as I overclock just a bit my pc crashes (crash, to be exact, it blue-screens and show this message: ' a clock interrupt was not received on a secondary processor within the allocated time interval') on prime 95 within a minute or 2.
One of the settings I used in BIOS:
All default, only things changed:
CPU ratio = 20.0 x
BCLK freq. = 150.0 Mhz
It crashes on prime 95 within 2 mins
Other setup, which I copied from
http://www.xbitlabs.com/misc/picture/?s … pg&1=1
Crashes within just seconds
All the time I monitor the CPU temp. and it always stays below 70 degrees C.
The default clock is good enough, but I know for sure that I should be able to OC this CPU to at least 3.8 Ghz with this cooler installed. So far I don't really have any idea why this is happening, anyone have any idea what is causing this?
I have googled for a while, but I haven't found anything relevant...
