I have an Alienware M17x with an Intel Core 2 Duo P8600 2.4 GHz w/ 3 MB Cache. When I received it, it had Vista and a 5+ processor rating in the Windows Experience Index. I reformatted the hard drive and installed Windows 7. I've loaded all the drivers I can get from Dell, and now when I re-run the score all my numbers seem good except for the processor: it's now a 3.2.
What driver could I be missing that would affect the CPU performance so drastically like that? Is there a setting somewhere that is default to "run CPU at half speed" or something like that?
I checked the power states, and while plugged in the Minimum Performance is set to 5%, the max is 100%, and the cooling is Active, so the fan will turn on before the CPU decreases its speed. The fan never came on during the test.
