Maybe the score was 11.5 for the processor but it wrapped around, so it only shows 11.5 - 7.7 = 3.8
ok, I'm joking, but since none seems to be answering, I thought I might break the ice...
Did you try any programs like CPU-Z, HWMonitor, running in the background while you do those windows tests, just to see what min/max in voltages and Mhz you're hitting on your CPU ? and maybe post screenies of both after tests done. Though, you might have better luck asking this on a windows 7 forum somewhere? (no idea where though)
