I'm having a problem with the CPU Multiplier with the Q6600. In BIOS it shows up as x9 but when I load windows and load CPU-Z it is showing x6. I'm running the processor on an Abit IP35 Pro. Any ideas on what would cause this? Also, Core Temp will sometimes show the correct FSB with the correct Mulitiplier. Has anyone else had any problems with CPU-Z?

Q6600 Multiplier problem

You probably have EIST or whatever like that turned on in the BIOS. What this does is dynamically drops the speed of the processor when the extra performance is not needed. If you load down all cores and then fire up CPU-Z I'm sure you will see the multiplier at the correct 9x. Either that or just shut that power saving stuff off like I do.
Yes, that's EIST. There's no reason to turn it off unless it causes you problems though - it doesn't mean the system is running slow because it will automatically return to full speed once the CPU is under load. It just means that the CPU can run a little cooler and use a little less power on idle.
Ah. I was going to post this same question. Will the feature affect overclocking the proc?
@lodingi - the only effects will be that your multi will drop from whatever down to 6 @ idle. So a q6600 @ 9x333 will bounce around between 9x333 on load to 6x333 on idle. No ill effects on my system. It's too bad one cannot define the vcore for a speedstep_low state as well as a speedstep_off state. My q6600 can do 1.000 V running 6x333 and 1.2625 V running 9x333. Oh well.
Yeah, I agree with that.. I was disappointed to find that setting any manual Vcore causes SpeedStep to stop changing the voltage. I'm actually running my Q6600 at stock voltage (1.25V), but leaving it at Auto causes the BIOS to overvolt it, so I have to set it manually.
It is 9x333, but I've not had time to work out whether it's minimal yet; I'll have a go when I do get some time. 1.25V is the VID for my chip.
The BIOS tries to put it to 1.35V as soon as it's at 2.7GHz, which was entirely uncalled for and makes it run much hotter.

Thanks, I'll keep that in mind.
I disagree.. we could do with less people saying 'OMG multiplier is 6x
' but it's generally a good feature otherwise.That's the way EIST is supposed to work - it drops the multiplier to 6x while idle, but increases it to 9x on load. If it stayed at 6x all the time then the multiplier would have been set to 6x in the BIOS, most probably. The OP says "Core Temp will sometimes show the correct FSB with the correct Mulitiplier", which suggests it's working correctly.
