hey guys..
my celery 2-566 with a golden orb and abit BH6 rev 1.1 mobo can boot into windows at 118*8.5 (1001mhz) but freezes when accessing any 3d apps..

heat doesn't seem to be the issue either..

at 1.7 volts 113*8.5(960mhz) boots fine and i can run it for agaes with no probs.. but when i start mdk2 or 3D mark 2000 or any 3d game, it freezes..

hmm..

at 105mhz bus (893mhz), everything is sweet.. (1.7 volts..) actually works fine at 1.65 volts also..

if i go up to 110mhz bus, it freezes in 3D games.. nothing else..!!
i can play all 2d games such as star craft or pharaoh for ages..!!

reckon it's my cideo card? not being able to handle the extra MHZ in the AGP bus..?

the CPU seems like a wonder but only rns 3D games at 105*8.5@1.7 volts..

heat doesn't seem like an issue..

thanks for any advice..!

P.S.. i've tried changing CAS latencies.. does nothing much.. my RAM has been working fine at up to 133mhz in another machine..! so it's not the RAM i think..

any BIOS tweaks i should try..??
