The BIOS procedure?
No. You always OC through the BIOS. On reading this a second time he must have had his RAM linked. There's no reason to link it unless your going to link and sync but even then you'd do it after getting the CPU stable. He'd have been better off to leave it unlinked to begin with, get the CPU up to speed then bring the RAM into sync if possible then link it. The way he did it he had two points of potential failure and there's no knowing which it was. Then he introduced yet another point of potential failure by jacking with the NB. You don't even have a stable OC on the CPU yet and your messing with the RAM and the NB at the same time?
Although I'm afraid to suggest it, nowhere in his proceedure did I see him raise CPU voltage, most likely because the RAM stressed before he got that far .
As to the RAM itself, If you're going to overclock it you have to loosen timings but if your going to underclock it you might be able to tighten them up and get back some lost performance. So he stumbled into slowing down the RAM while loosening the timings or slightly bumping voltage might have done the trick. Either of those can be tricky so what he did was probably for the best given his inexperience.
I was also curious about the initial 5 Mhz raise in the FSB with a bunch of testing then later just jacking it up then jumping 500 Mhz per step? Where did he learn that?
Hey, I get it, he's a kid and he wants it done now but if he wats it done right then some more reading and research and trying it again with better information would probably do a world of good for his PC. As it is who knows what he's got.
