Hi people, I have a quick question regarding my North bridge clock sitting at 3024.4mhz, Shouldn't this show as 3000 to sync with memclock?

Is there something I've inputted incorrectly that has caused this?

Or is it due to my system setting the fsb to 100.8mhz by its self even when set directly to 100mhz in the bio. Why has it changed from 100 to 100.8?

Thankyou in advance
