I've tried testing the fsb with just my cpu+fan, voodoo3 card, cosair xms pc3200, hard drive, and i tried setting the fsb at 166mhz and it won't boot into windows, I set it 1.775v and the same, then tried 1.8v and then it didnt post and bios reset itself next time i booted up. I didnt try any setting lower or higher then 166mhz because i thought it should be able to boot at 166mhz?
Update:
It boots up fine in windows, but havent tested it with any benchmark software yet. Also when i use cpuid it shows my ram only at 300mhz, I dont get it suppost to be a pc3200.

I now tested the fsb at 160 and it boots up to windows fine with the memory on the slowest timings. But again i didnt use any benchmark software to test it at that speed. Cpuid reports ddr speed at 320mhz. I think i got ripped off.
Another thing i dont understand is when i try to raise vcore it doesnt seem to go any higher then 1.8v and thats what it was at default.
