Max voltage for 24/7 overclock

post #1 of 2
Thread Starter 
Back when SB first came out, it was said that the max voltage recommended for a 24/7 overclock was 1.38V. Given sufficient cooling, however, would it be safe to use something like 1.45V on a 24/7 overclock?

Currently, my max temps in Prime95 at 1.392V and 4.7 GHz are ~63C with the NH-D14, so I feel like I have a little more headroom in terms of voltage.

Max is 1.5v

Most people TRY to keep it under 1.4v thought to prevent "faster" chip degrade.

However, if you've got it under water or a really nice cooler, as long as it's under or a little over 1.5v you should be fine given the temps are staying below 70ish-75 degrees.

Never go over 1.52v+ for 24/7 though unless you REALLY need too

I personally never go that high, even though I have good temps, I don't like pushing that much juice into my chip. Max I PERSONALLY will go is 1.47-1.48v.
