|There is no FSB on AMD systems. Have you ever overclocked before??|
Your stock CPU settings are 8 x 200MHz. That 200MHz is the called CPU frequency aka CPU reference clock. You need to increase it to 250MHz. But you need to realize that increasing the CPU freq has a domino effect on the PCI, PCIe, RAM, HT, so you have to adjust those settings so that they don't go out of whack & prevent the system from booting.
EDIT: sorry, I overlooked the model number in the OP.
