Damn that 0.02 burning a hole in my pocket - but what bothers me is that it seems the first thing superhero did was to start railing against the reseller - a real superhero I think would have been asking for help or ideas. Every overclocker knows, or should accept, the fact that he's taking a gamble - that's part of the fun, isn't it. In my limited experience, I usually find the problem is mine. What is the tolerance on the mobo voltage setting? I don't know - could be the chip voltage tolerance is to allow for the mobo mfr tolerances, and you could have a board/chip combo on the bad side of the tolerances - this chip is apparently more sensitive to voltage than say a celeron. When I run a program such as MotherBoardMonitor, it always reads at least a half volt higher than my setting - I don't know which is correct - part of the gamble - and could the mobo voltage regulator change over time - and we're talking older mobos here.
As most of you know, some resellers, will RMA, and then charge you a big, but probably realistic, fee if the part tests okay.
Now if they took the chip back for testing and it tested okay, I think you probably wouldn't believe them anyway. If they then send you another new chip, then they're stuck with a used one. So, if you were the reseller, would you have just given a refund and taken the loss, when you're selling at bargain prices? Superhero??
