Hello! I've recently built up a real 'cookie cutter' rig as follows: MSI P67A GD55 B3 i5 2500k 8gb Corsair Vengeance RAM KFA2 560Ti Now the RAM is 1600mhz however when I go into CPU-Z it shows PC3-10700H (667mhz). In the BIOS I have it manually set to 1600mhz and XMP enabled, yet it continues to stay at 667mhz whereas it should be 800mhz... The BIOS is fully up to date, and the CPU is overclocked to 4.8ghz. Running on Windows 7 64bit. Any ideas why I can't get the RAM up to full speed? Cheers, Fish.
