I just bought a new system that includes a mobo with a DDR2 800 memory standard. The RAM installed is DDR2 800 4-4-4-4-15-1T SLI Ready (mobo is SLI ready as well). I set the BIOS to read the RAM as exactly what it is - DDR2 800, 4-4-4-4-15-1T. When I open up cpu-z and go to the memory area, it shows both of my sticks running at 400MHz! Something's wrong here... anyone have any ideas? The timings are correct, and it displays PC6400 like it should, but the MHz is all wrong.
