me
AMD Athlon 64 3000 AM2 @ 2.03 only, dare not OC much
MSI K9NU Nvidia/ULi M7
2 x KVR 512 MB DDR2 667
stock cooler

I cant start windows at HTT = 266, even at 250mhz also not stable alrdy
for those using this mobo, must it raise the chipset voltage to OC properly?

@soulfly,
I am using default Vcore for both CPU and chipset, I didnt use RAM divider as I have no idea on how the settings should be, I just set it to auto SPD or 667MHz, I read a review earlier that this mobo have to raise the chipset volt. to perform stable on >250MHz FSB

and the HTT multiplier?? Dunno about that, just set it to 800MHz
