is CPU FSB fluctuation normal?

post #1 of 5
Thread Starter 
My FSB is fluctuating .1-.2Mhz on CPUZ. Is this something I need to worry about?

I don't think so. Mine fluctuates between 3520 and 3519. Never had an issue.

I also believe this to be normal. My frequency also has small fluctuation.

Yep. Small fluctuations in frequency are not a problem. Also, small, infrequent fluctuations in v-core with a CPU under load are usually not a problem either.
