DFI AD77 Infinity Overclocking?

[foxkm]

I have a DFI Infinity and an XP1800+ unlocked. I currently have the chip running 1900+, but thats all I can do. I wanna get the board running 166fsb, but when I set the bios to set the multipler to 9.5 or lower, and then power down to jumper to 166. It won't post. I have tried increasing the Voltage on the CPU/memory/chipset, but nothing. Has anyone else had any luck with this motherboard?

Also, I have PC3200 Running on the board with the memory settings tweaked. Weather its running 400mhz, 333mhz or lower, SANDRA 2003 always reports the memory speed to be that of PC2100. I am using the latest bios. Anyone else have any luck?
