CPU Z switching the multiplier

[paddi70]

For some reason CPU z is switching its reading on my overclock, I have is set on multipiler set on auto in tthe bios for the e6300 (which is x7). But its switches between 6 and 7. So set it to 7 and it does the same?
Any ideas, full spec in sig. Many thanks in advance. P

Awesome, sorted many thanks again. I take it if \i leave it it will run at 7 when required, then 6 when nothing is happening?
