Slower performance from quicker CPU?

Hi guys,

I upgraded my CPU from:

Intel® Pentium® processor E2160 (1.80 GHz, 65W, 800MHz FSB, 1MB

to:

Intel® Core™ 2® processor E7400 (2.80 GHz, 65W, 1066MHz FSB, 3MB)

Not only does my PC seem to run slower, the Windows Experience score for Processor, Calculations per second went from 4.8 to 4.5.

I only really use the machine for web browsing and Football Manager but the FM is performing a lot worse than before.

Any ideas why this would occur?

The CPU is just in a HP dc7700.
 
Thanks for the replies guys. Funnily enough when I put the CPU in I got a Microcode error, I updated my BIOS as HP suggested and thought that would be that?

Here is a screenie from CPUZ, can you shed any light? Oh and I didn't reinstall Windows when changing the CPU.

I've gone into the BIOS, no such options. :(

I guess I should should check the HP 0A54H board supports this processor? I can't find any BIOS updates other than the microcode one
 
Sits at 1596mhz under load.

The index score was completely accidental seeing it, I don't take any notice to it but it took me by surprise it being lower.

It's not in my head that the PC is running slower though!

I too would have thought the microcode update would mean the CPU is able to be used in my PC.
 
Cheers. Trying to run it as Admin and not letting me open it. Will keep trying.

Bah, it's not having any of it, just kicking up an error saying I must have Admin rights to run, I am doing so and it can't find the rtcore64 file which is clearly there,

Is there any alternative software that runs similar?

Hmm, works on my Laptop which has XP on.

EDIT: Seems you can't run this on Win 7 without the signed driver. Which leads me back to the original problem

Wahey, found a signed driver, will have a look now.

Not sure if this is the best route for me, I have no idea what I'm doing :D

Going to see what they suggest on the HP forums, thanks for your help
