Poor rating on good processor (WEI 3.7 on 3.2GHz quad)

This has been bothering me since last summer, and I'm finally getting around to poking at it. Does anyone know why the Windows Experience Index of Windows 7 is rating my processor a 3.7 when I have a AMD Phenom II X4 955 Black Edition Deneb 3.2GHz Socket AM3 125W Quad-Core Processor Model HDZ955FBGIBOX that should be rated much higher?

With this score, it is by far the lowest-rated component of my computer but I feel confident it should not be. I believe there is some issue with the WEI, because I have not noticed my processor behaving badly in daily use.

Just to be sure of that last point, what good benchmarking freeware could I use to independently test that my processor is not mysteriously running far below where it should?

Here are the rest of my stats, just in case it matters:

Motherboard: GIGABYTE GA-MA790XT-UD4P AM3 DDR3 AMD 790X ATX AMD Motherboard

Video Card: HIS Hightech H489F1GP Radeon HD 4890 1GB 256-bit PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card

Optical Drive: Sony Optiarc 24X DVD/CD Rewritable Drive Black SATA Model AD-7240S-0B - OEM

Hard Drive: Western Digital Caviar Black WD1001FALS 1TB 7200 RPM SATA 3.0Gb/s 3.5" Hard Drive - OEM

yeah try 3dmark, get 3dmark 06 because you have a ati, its not freeware, but you can use most of it for free. 3dmark vantage is better for physx/dx10 cards apparently.

Is windows lowering the GHz of the processor? if so that would cause a lower mark than it should be.

For example, windows lowers my 2.4ghz q6600 to 1.6ghz, even though ive changed settings in the BIOS so it doesn't do that. but w/e. it doesnt matter much anyway since as soon as the cpu goes like over 10% or something it goes back to 2.4ghz.

Windows experience index is a poor benchmark anyway.

Okay, first thing to do, is look around the BIOS, there might be a option called 'let windows manage my cpu' something similar to that, disable that.

Also check ur temps.

Thanks for everyone's help -- after I was pointed in the direction of 3dmark I learned that there really was a problem with my CPU and not just with WIE.

A little more poking around the interwebs revealed that this was probably due to a BIOS problem. Flashing a BIOS update solved the issue.

My CPU is now running at full speed and my WIE score is 7.3. I feel a bit silly for using a computer for about 8 months without noticing that it's CPU was at about 1/3 power, but apparently I managed just that.
