han888, you say you got your 800 to work at 1000 in windows...
i had a cusl2 (till i fried it... long story) anyways i could get mine to post at 100 using a 125fsb but because of the pci clock being so high it killed my windows.
how on earth did you manage to pull that off?
i ended up using an alphapep66 with a 55 watt peltier to boot up to 133fsb. didn't have time to figure out how to get it 100% stable as something went wrong and friend the mobo... looks as if the solder on the back of the agp and pci slots began to melt or something. sort of like a white chalkey looking substance.... like a spider webbing inbetween the solder spots.
i'm current cruising along at 1066/133fsb on a BX133 from abit. no peltier required
just got to get my agp stable and i'll be good to go
