Top ideal 24/7 Vcore - 2500k - Page 3

The maximum VID in the vid range was 1.3625v for the core 2 quad 45nm's. And keeping them below 1.3625v was NOT insurance that they would not degrade, but rather, that the chips would not become non functional. Some people ran them at 4 ghz and 1.3v, and found that they had to raise the vcore a few notches over several weeks/months, because they started crashing. This VID rating has absolutely nothing to do with what is "SAFE" for a CPU, because this actually changes CPU to CPU. Some cpu's degrade at low voltages, and some don't. That's why different CPU's have different default VIDs. The absolute maximum and minimum ratings apply to all, though.

This happened to me, except it wasn't that the CPU was no longer stable at that load voltage; it was because the board would no longer supply the same load voltage at that setting. I had to raise the voltage a few notices to deliver the same load voltage as before.

How did you find this out? Were you using a DMM? Or the actual sensor voltage was dropping? Mosfet degradation?

With CPU-Z and confirmed with DMM.

Ok, so my overclock is indeed doing nice and stable after 10 hours (approx) of Prime95 - 4.4GHz @ 1.325V. IIRC this will not cause my CPU to degrade quicker, right?

These chips haven't been out long enough for anyone to know what the tolerances are before degradation. If you don't want it to degrade, don't overclock.

However, in my experience with previous chips, 1.325V shouldn't harm Sandy Bridge.

ASUS Recommends staying under 1.425v so I'd use that as a point of reference.
