i7-930 no longer stable

post #1 of 5
Thread Starter 
So here's the situation. A couple months ago I built my sig rig. I successfully overclocked it to 4.2ghz stable and ran it like that for about a month. I have since become more concerned with my overall power consumption so I backed it off to 3.36 with stock voltages and power features.

The overclock bug bit me again today so off I went to the bios and entered the same values I used before to get 4.2. But now it won't even boot with those same settings.

previously stable OC settings:

21x200
turbo off
hyper off
C1E/C3/C6/C7/EIST off
Bi-directional on

Vcore - 1.35000
QPI/Vtt - 1.215

I don't understand this drastic change in behavior... These settings went from 12+ hours stable to being unable to boot.

What do you think?

I am also facing the same thing, even if i have noted ever thing in bios. Sometimes when i am stable at X point and change it i never comeback again to the same point with the same bios setting. I really dont know why!!

Well apparently I missed something because I got it to boot up at 4.2 and ran some test and it held up. Maybe I overlooked something on the first retry.

Now I've settled for 3.8 with all stock voltage settings so that I can take advantage of the power stepping features. My only bother is that i'm forced to run my memory and 1448 instead of 1600. However I'd say gaining 1000mhz on the cpu is worth losing -200mhz on the ram
