Overclocked Q9650 issue (2 cores running below speeds)
 
I have my CPU overclocked at 4.0. According to Coretemp and CPUz, Core#2 and Core#3 are running on 2.4ghz, even when loading at %100. Only Core#0 and Core#1 are running at 4.0 with multiplier at 9x as opposed to 6x with the other 2 cores that are running below speeds.

Any idea why this is happening?

what happens when you down clock to stock?

When I do that all the cores maintain 3.0ghz

Just wondering if your temps are too high and the cpu throttling in bios is kicking in to slow things down.
2 cents worth sounds a bit odd

Oddly enough, I am running stock speeds right now and the same 2 cores are now running at 2.0ghz instead of 3.0. Cores 0 and 1 are fine. This is frustrating.

been having a look on the tubz , but can't find anything. Sorry to ask this but have you closed down the speed step stuff in bios.

Also check you cpu speds with different app . CPUZ

I have EIST, CE1 and speed spectrum disabled. I Coretemp and CPUz both report the same low speeds with the same cores. Thanks again for your help.

The 2 cores for some odd reason decrease to 6x when they should be at 9x. FSB is the same as it should be for the overclocking I aim for.

Good luck bro

Have you tried increasing the voltage?

No. But should it really make a difference, if even at stock settings the problem remains?:(

Oh I didn't notice that. You may need to RMA the chip.

You have another processor you can try? Are you sure your BIOS supports the Q9650? I needed up update my BIOS to handle the 45nm chips from Intel.

Well I got the other 2 cores running at 4.0 now. But EIST has to be enabled for that to work. So now I have to settle with windows speed control.
