OC'g AMD 1200C - which method is best?

Upgraded to an Epox K8HA+ recently. Had to replace a defective XP so while waiting for the new CPU, dropped in a 1200/200 Tbird-C which was unlocked from the factory. After bringing up the system stock at 12X100FSB to make sure everything was OK, I jumpered the mobo to a 133FSB bus and set the multiplier down to 9. The system would not even begin the POST. Eventually jumpered the board back to 100FSB but adjusted the FSB within the BIOS to 133 with the 9 multiplier which worked. Am I losing any performance by doing it through the BIOS adjustment rather than the board jumper? Any suggestions?
 
You should not be losing any performance by doing it in the bios. However I am kinda wondering why it works from the bios but not by jumper.
 
My guess is that during the initial stages of the post, the mobo recognizes the default multiplier of the CPU and applies that to the default bus speed, jumpered on the board. Further into the POST, the bios settings take precedence...I think. I guess the real question is whether all components on the board are stepped upto 133 properly if set within the bios.
 
Setting it in the bios should have all things working correctly. Try using a program to check to see if you really are at that speed like motherboard monitor.
