Hi,

I have a C2D E6400. It's rated at 2.13 ghz, but when i go into Control Panel and look at system it shows me that the cpu is actually running at 1.6ghz. I tried overclocking but i only got to 2.16 ghz at the most. Can someone please explain why my cpu is clocked so low, and also why it has such difficulty overclocking.

Thanks

Why is my CPU not showing correct speeds? Did you check the speed while it's doing something CPU intensive like running a game?

What motherboard do you have? Or what is the make & model of your PC?

I've used CPU ID and i have it OC'ed to 2ghz now, and thats the most it shows. I have a gigabyte 945PL S3 mobo. Also temps are around 40 degrees celcius, so thats not an issue

I just figured out why. I looked at a review of the mobo, and apparently C2D's like a 1066mhz fsb, whilst 945PL systems run on a 800mhz or 533mhz FSB. Know if i can do anything about it?

Your right - it's the 800FSB of the Gigabyte 945PL S3.

Without changing motherboards I think you've done about everything you can.

Thanks for your help anyway. I really think its time for me to get a new system...
