Wierd overclocking results. One program says 2420mhz, the other 2375

When i go to 210x11.5=2415, or as Cpu-Z says its 2420 cuss the fsb is 210.5

Anyway, MBM5 reports my cpu @ 2375mhz, and goes up and down tfrom 2420 to 2375 every like 2 seconds, yet when im @ 200x12 for 2400mhz it reports as 2403mhz which it should for both programs.


Whats up with this ?

Cycling between the 11 and 12 multiplier perhaps?

No i think it was a problem wiht the actuall Fsb, whe ni boot @ 210 it reports @ 418 mhz its soppose to be 420, so i tried going to 209, and it still reports @ 418mhz, but MBM5 and Cpu-Z now finally agree with eachother and thier both staying @ 2415, and the fsb is 209.9
