X4 620

I have posted this elsewhere so if you have seen it before my apologies for those that havent.

I recently had one of these and i am pleasantly surprised by it. At a similar speed to a stock 955, ie overclocked to 3.2 Ghz it is, for the most part, similar in performance thanks i suspect to the extra bandwidth afforded to it from the higher FSB (250) and mine went onto 3.7ghz before running out of steam. I was unsure of what is regarded as "safe" voltage wise so err'd on the side of caution and kept it to 1.45v, i have since been told "safe" is upto around 1.5v. I haven't bothered priming it yet but it went through pcmark vantage (takes well over an hour) so its reasonably stable i would have thought) anyway i would recommend one if you can't quite stretch to a Phenom. .

Its safe aslong as its cooled properly.

Indeedy, i never saw mine go over 45, according to coretemp, at 1.4v(ish).

Very impressive, although I've seen this before
