Determine a good chip

When I got my Phenom II X4 965BE 6 month ago, I’ve just blown three socket 775 valueboards trying to push my q6600. So I wasn’t going to do some crazy overvolting… for the time being

The plan was to see how much I could get on stock voltage, so I just tried raising the multiplier and immediately got 3,7GHz stable.

I was quite impressed with this kind of clock on stock 1,4 voltage, which led me to believe I really won the lottery.

However lately…

I’ve been trying to find a stable 4GHz setting, and it’s been a battle!

When only raising the multiplier to x20 there was no way I could get it stable, I went all the way to 1,58v.

The only way I was able to get it stable at 4GHz, where by lowering the multi to x16 and raising the FSB to 250 – but still I need 1,55 vcore.

Now I’m perfectly happy with bombarding the processor with 1,55v, and if it blows in five or six month – so be it. I might even switch back to my 3,7 setting, just to keep the system silent.

But back to the headline of this topic, was my assumption that I received a good chip wrong when achieving 3,7 on stock volt?

Might I have a weak link in my setup, or can the processor limit just appear out of nowhere?


Cheers.

Setup:
