CPU not going full speed.

probably its downclocked since its idle, but if u stressed it, it should go full speed. strange... have u been messing around with the bios? try to dissable EIST in bios to keep the cpu at full multiplier.

Run OCCT and see if the speed goes up as the test runs. sometimes priming doesnt bump up the clock.

Tell us what chipset are you using. Also check in bios FSB is set. It should be 200, if its less then set it to 200mhz. It will be working at full speed, then.

I can't set the FSB in bios.
Also something called clock speed is at 200 MHz.
If I change it to 265 MHz (the most it lets me) it raises the CPU speed to 1800 MHz.
But then it sometimes freezes in games, making me restart the computer.

This is the CPU in CPU-Z:


Thanks.

Strange, I believe the E2xxx series have an FSB of 800MHz (200MHz to be exact). I am wondering why yours is set to 533MHz / 133MHz.

What is your exact motherboard model (a screenshot of the Motherboard tab would do)

our pix are amazingly similar... now i need a new one

Yeh sure.
This is the motherboard tab in CPU-Z:


Should I try updating my BIOS then?

Thanks!

I've just brought a 4-pin to 8-pin converter for my motherboard.
I'm not sure if thats made any difference, but I went into the BIOS and change the clock speed from 200 MHz to 265.
This is my CPU now:


So now I get around 2 GHz.
Still not the whole 2.4 though...

Does anyone else have any ideas, before I flash the bios?

Thanks

the clock speed in your bios you're talking about should be the bus speed in cpu-z. that's an fsb800 processor and the 177.3 x 4 = fsb709.3, which it shows just below it. you're underclocked. if i were you i'd download a new revision of the bios and flash it. or if there is no newer one, reflash with the current one. oooor at the very least clear your cmos so all of your settings go back to defaults and give'er one more go.

oh and your multiplier is just fine, cpu-z shows it as x12 which is what it's supposed to be. 200x12=2400mhz. you've just got somethin wacky goin on there.

If you don't want to flash the bios, did you try setting default in bios? This might help. However I assume that upgrading bios is the best option. And btw, your mb does support this cpu.

You might as well get a new board because tracking down another chip if you could even remove it will very difficult now give what others have suggested or flash it. Look for a nice problem free board on newegg for like $40-$75 if all else fails.
