My latest attempt for 500MHz FSB has failed as usual. I updated to the beta 0501 BIOS, and I can get 495MHz fine and linpack stable, but at 500MHz the system BSODs at the windows loading screen, regardless of voltages I use. Voltages for 495 were 1.531 on the CPU (with LLC), 1.69 on the NB, 1.6 on PLL, 1.38 on VTT. Admittedly, all DRAM settings and GTL settings have been left at auto, I don't have the patience to mess with them. Maybe if I did 500MHz or higher would be possible, but oh well.
