I'm O.C.'d in the BIOS just like always when I had XP (just installed Windows 7 Home Premium 64 bit) with a BCLK of 200 and a multiplier of 20 so I'm at 4 GHz. I now notice that when I open up CPUz on the first tab it says 20 multiplier and 200 BCLK but then changes to a 12 multiplier and 200 BCLK. When I go back into the BIOS it's still at 20/200. Also in the Control Panel>System it says i7 email@example.com GHz and then it says 2.67GHz after that when it should read 4.0 GHz. What's up with that?
