Ok,so i just put a very mild OC on my e4300,210 FSB.

on start up screen it reported (210x9)1.89,started cpu-z and it reads

Core speed:1260.0
Multi:x6
Bus speed:210

so what the heck is going on,CPU-z just reported wrong?

also it's reporting my mem as runing at 303.

really lost as to whats going on,never had CPU-z report anything wrong.

Does CPU-Z even support that model yet?

Whatever your BIOS says, I'd trust that.

It's not reporting anything wrong. This is a power saving feature called EIST that is enabled by default on all Core2 chips.

When your CPU is at zero percent load, the motherboard switches to a 6x multiplier to save power and reduce heat. As soon as the CPU starts getting a workload though, it will jack the multiplier back up to 9. You should be able to disable this in the BIOS.

Will that feature actually degrade performance? If not, I don't see why you wouldn't want that running. :)

It wouldn't degrade performance at all. But at extremely high overclocks it can lead to instability.

For example, at a FSB of 444, you're CPU will be throttling between 2.6GHZ - 4.0GHZ. Not exactly the most stable thing in the world. Overclockers typically turn it off, but at stock speeds it's best to keep it on.

Ah. I get what you're saying. I'll have to remember that when I overclock my E4300. Thanks. :)
