Hello,

I was recently forced to upgrade OS to WinXP. Now windows crashes trying
to boot-up unless I set CPU down to 450 in bios, it's a 600EB. I don't
understand ... this machine was rock solid in 98se even overclocked to the max. I did have problems in 98 using the upgraded Asus Gforce 6800 video drivers, (any drivers except stock) experienced the same symptoms I have now. I noticed that the new drivers enabled side banding. I've
upgraded the bios on both the mobo and video but that still doesn't
help. I have Asus P3B-F set in jumper free mode and was running at 133.0/44.33 but now can't exceed 100.3/33.43. This has me baffled, I ran at 133 for years without a problem till I upgraded drivers and Asus Live :/

Any help would be greatly appreciated I as I would like to run this CPU at least at it's 600 rating.

Asus P3B-F Bios 1008
PIII 600EB
Corsair PC133 SDRAM
Asus Gforce V6800 Deluxe TV in/out bios 2.10.02.10
Emerax? 300W PSU

I know this computer is at the end of it's road. However, I'm waiting
for the Asus P5K series mobos to go mainstream with DDR3 memory.

Thanks in advance

Ram is not a problem. Something in the driver version for this video card. If I reinstalled 98se with original drivers that came with the card I could probably overclock this CPU. Like I said.. this worked fine for years @133 but in winxp system boots fine then winblows hangs. Maybe I'm missing something in the Bios? My Graphic apature size set at 128. Also, the old drivers didn't have side band "enabled". Installing newer version of Asus Live in Win98 also caused instability symptoms. You think setting jumpers manually on the mobo could help?? FWIW.. voltage is 1.65. I'll try anything to regain 150mhz! Any other thoughts you might have would be greatly appreciated.
