I have this MB/CPU combo with 2GB 1333MHz memory running Vista Home Premium. The only changes I made to the default 0602 BIOS (latest from ASUS) is to disable Cool 'n Quiet, enable Unleashing Mode and set Active CPU Cores to 4 Core Operation. CPU-Z shows all 4 cores running at full speed (3416.6Hz). But running the PerformanceTest 7.0 CPU benchmark gives a CPU mark of 3481.2 vs 4452.9 and 4546.7 for 2 other identical MB/CPU combos from the PassMark database. I'm new to multicore CPUs and need some expert help to explain why mine seems to be running 25% slower. As I'm using this for HD video processing, I need all the speed I can get (I'll get to overclocking later!).

Does the PassMark database offer information whether the CPU's listed, are running stock or OC'ed?
Yes. They are running stock at 3412.3 and 3415.2Mhz respectively.
