Your memory is severely overclocked. It must be set to 667 MHz instead of how it is now at 800 MHz. Go in the bios, make the necessary changes, save. Reboot to Windows. Check the memory tab. If it is wrong, keep on trying until you get it right. If you can't get it right, contact the manufacturer of your motherboard and/or RAM.
Good luck and enjoy. (I'm done here, so if I don't respond any longer, it's only because I have nothing left to say and not being rude.)
