I saw something similar a couple of months ago here about a Sony Vaio. In my case I have an HP DV9330CA that has, according to the specs, BIOS and Belarc, an Intel T5500 Core 2 Duo running at 1.66GHz. Yet the Windows Vista Device Manager (Ultimate 64-bit) reports it as 2 T-7200's running at 2Ghz. Any ideas on why there's the apparent error?
