My Bios reports the FSB as 100 w/ a multiplier of 13. The Board is an AOpen AK77-8XN Bois Rev 1.15 (which is an AMD recomened board) has a 200Mhz FSB Jumper. I am running PC2100 DDR Ram an nVidida GeForce4 MX 440 AGP Card. When I set the board to 200Mhz FSB I get nothing. When I set it to 100Mhz it boots and reports the CPU at 100Mhz. How do I get the CPU to run at 200Mhz?

Thanks.

Uh, it's running at the proper speed. 100MHz is the REAL FSB speed, 200MHz is the EFFECTIVE FSB speed. The effective speed exists because the FSB is double data rate; that is, at 100MHz it does what a 200MHz single data rate thing would do.
