Default Re: Core i7 Overclocking thread

How common is it to find that one has to increase the voltage on their Core i7s as time goes on to remain stable at the same overclock? I used to be able to run my Core i7 965 at 3.8GHz at 1.22V for hours Prime95 stable (no bluescreening or restarts either, I just stop the test after a few hours). This was half a year ago.

A couple of days ago I decided to run Prime95 again on a whim to test some temperatures (I had just cleaned out my PC and reseated the CPU HSF). My computer bluescreened after 5 minutes. I had to raise the CPU voltage to 1.25V (without changing any other settings) to get Prime95 running stably again for a few hours.

I guess my hardware also changed in the meantime. I went from GTX 280s to GTX 480s and I added the Intel SSD. Could this also have caused my overclock to fail?
