My E6600 is running half speed :(

My E660 is only running at 1,2 ghz instead of 2,4ghz according to CPU-Z ( http://img232.imageshack.us/img232/191/cpuz2cw8.png ).

It's not only in CPU Z I can see the problem also in 4 other programs which do the same thing, and even when I turn on my PC, it says something like "E6600 2,4ghz @ 1193 mhz, 9x133mhz". The problem is also in games like TF2 where it doesn't matter if eveything is on high or low, the framerate still drops to around 15-20 fps when there's a lot going on. (I have an 8800GT and 2gbram and XP).

I have checked the BIOS and everything looks fine there, and I've tried turning Speedstep off but it didn't help. My motherboard is a Micro Star International MS-7267 with an Intel i945G/GZ chipset.

Please help me, this is driving me insane!

Looks like your bus speed got halved somehow. You can reset the CMOS to see if that fixes the problem, or manually adjust the bus speed to 266MHz.RayvinAzn

In the bios, the bus speed is at 266 MHZ.

And what is the CMOS?

Also, can it be the motherboard? I have Vista OEM version and I would like to install that now, but if I have to change the motherboard I won't install it now 'cause it can only be installed on 1 motherboard :(

Go to your BIOS, set your multiplier to x9 and turn off "C1E", that should fix it.Taiko88

I'll try that.

Can you explain what it is I'm doing?

C1E lowers voltage and clock speed to maintain low temps and stability and is supposed to high it when it's needed. It works pretty **** though and mostly will just kill your performance.

His multiplier is fine, its the bus speed that's dropping. And C1E doesn't affect the bus speed, only the multiplier.

Well my Bus speed is at 266 in the bios :(casparmorch

Got the latest version of CPU-Z? Sounds like it could be a problem with CPU-Z rather than your processor.

Got the newest version, I've even tried 3 or 4 other programs that shows the same thing and my games also run worse than they should, especially RTS games like Supreme Commander.

What is Prime95?casparmorch

It's a program that will run your CPU to 100% to look at load temps and stuff. Or you could try ortheus.

www.google.com

Done.

Which of the torture tests should I use? And can you explain what the program is doing?casparmorch

Any of them will work for what you're doing. And Prime95 basically just searches for Prime numbers. It wasn't actually designed as benchmarking software, but works very well for that purpose.

You don't even need to run it for 15 minutes. One minute should be more than enough, just keep watching CPU-Z (and just in case, it would be a good idea to use Speedfan or Coretemp to monitor your temperatures as well).

Nothing has changed in CPU Z.

Can it be some sort of virus or error in the Windows that makes it run slower?

You sure you've set the FSB at 266, and it's not the memory if you have 533mhz? On MSI's site it says you have to manually set the FSB at 266 by overclocking it, because it doesn't officially support that FSB. So you need to set the clocking options to manual, and raise it to 266 if you haven't. Leaving it on auto will default to lower FSB's.

If you've already done that, check for BIOS updates, that would probably solve it.

Oh...

I'm a crazy **** 9MHZ OC!!!

Brb, testing it.

The Bus speed went from 133mhz to 134mhz. So basically I could just "OC" it up to 532 mhz.casparmorch

Huh. Reset your CMOS, and try flashing the BIOS maybe?

What I meant was, since it's showing double as many MHZ in the bios as I actually get, I could just double it in the bios and then get the amount of mhz I would normally get.

Already tried flashing the bios, I'll try that CMOS thing.

And what is NB voltage? Might it help if I used a better PSU? The one I have now is 400mhz but I could install one with 700.

Often times you need to raise the northbridge voltage when you overclock your FSB, which is what you are doing to get to 266mhz since it was not intended to run at that spec. I see from your screenshot it is at 1.55v, where is that on the available options, lowest, middle, highest?

Oh wait I don't even think you can change it, it's greyed out.

This is the weirdest problem ever.

Could it be a virus or something software related?

**** :(

According to this, it should be able to have a FSB at 1066. Couldn't it be that the motherboard is broken somehow and needs to be replaced?

Dude do what ppl have suggested before jumping to wild conclusions. Reset the cmos by removing the mobo battery and and power cord for 30sec. Or you can find the jumper but that's more of a pain especially if your case is small. This puts everything in your bios at default, so see what it sets your fsb and cpu freq at. Make sure you set the time and date correctly before going into Windows.

If it's still jacked after that, try lowering the fsb down to 200. Should have no troubles at that and your cpu should be 1800mhz. If that checks out, start increasing it by 10mhz till you find the limit.
