Core i7 Too Much Vcore?

post #1 of 2
Thread Starter 
Been messing around the with vcore on my i7 @ my 3.8Ghz stable OC.

If I raise my vcore to 1.37 I crash when I run prime95.

However, at 1.35 I am totally stable at the same given frequency?

Shouldn't this be the opposite?

If you're unsure of things...it's always best to test multiple times. Often instability problems are very ambiguous so keep checking for different results. Sometimes higher voltages may only like certain temperatures...so be sure you have some proper cooling. Otherwise you should double check if you really are stable or at the actual voltage through CPU-Z putting into consideration your LLC (Load Line Calibaration) / Vdroop / Vdrop.

One more thing...is there a reason why you're increasing your Vcore when you're already stable at your current voltage/frequency? Doesn't really make sense if you're not trying to increase your overclock passed 3.8GHz. Rule of thumb is usually...increase your overclock and then tweak your voltages if you're running into instability problems. Once you found your sweet spot...you decide if you want to tweak around your memory timing/frequency/ratio. Not everybody is the same though...so do whatever works best for you.
