MSI K8N Diamond Plus won't overclock.

Hi, my friend has an MSI K8N Diamond Plus with an Athlon 64 X2 4400+ and I went to overclock it for him, and even though I changed the FSB the clock doesn't change AT ALL. It just sits there at 2.222. It's not like it crashes or anything, the computer boots and everything, but the clock is never changed, in the BIOS the FSB is still set at whatever I set it to, and it's not like the multiplier changed or anything. So I have no idea why it just won't overclock.

Someone please help me, and thank you,
Kraztsun

Can anybody help me?

Bump.
