Problems with my I7 950 OC

post #1 of 5
Thread Starter 
Hey guys.

I recently started to dabble in the world of overclocking and managed to overclock my I7950 to 4.02 Ghz stable (20 runs of Linx using 25000 problem size). Since achieveing this my system has been running fine but i wanted to see if I could reach 4.2 stable with decent temps. I have tried various settings in the bios and kept attempting the linx tests .... sometimes I would get Bsod and others I would just get a failed test. Eventually I decided to revert back to my stable 4.02ghz OC.

Now when I run linx test with my original 4.02ghz OC settings it takes about 1 min longer per run and my Gflops have reduced from 52 to the mid 40's!?!? Also my core temps (as seen in Real Temp) are reduced by about 8 degrees Celsius.

I've now also come across a new problem and that is that with my OC settings my system now wont boot to bios. The screen remains black and then restarts forcing me to use factory settings.

I am relatively new at this, although I have been reading up on it. Any advice or help would be much appreciated.

try raising the vcore a bit if temps are acceptable. Your cpu may not be getting enough juice.

if you used too much vcore it could have possibly caused degradation, but it's unlikely. Usually if my bios is being funky I reset the settings to default, boot into windows/mess around, then reboot and oc.

Thanks for the quick replies guys. I also thought that maybe I had used too much voltage and damaged a component. But after some more tweaking I am now in windows running at 4.02 ghz again. Failed my second run of linx though (but Gflops were back up to 52+)... I am upping the vcore slightly and trying again. Ill let ya know
