I played with the HT Ref clock quite a bit last night, and I can still get close to 250 using AOD, but trying to get it to boot from BIOS above 235 was pretty much impossible, it may be a limit of my board...

I even cranked up the HTT/HTR/SB voltages and it still seemed to hit a wall..
I know the chip will do 250, cause 250x10x8x8 was my everyday stable on the K9A2... Just thought I'd let ya know my experiences..
From what I can just remember, it used to be that computers overclocked better under Win98 than under XP. I think that each succeeding release adds an extra level of complexity that means a previous-stable overclock cannot be maintained.
