I overclocked my processor and activated the X.M.P. profile which sets the ram at 1600 MHz (which should show up as 800 MHz) but CPU-Z reports 725 MHz. What's the problem here? When I boot up they do show up as 1600.
I tried to do everything manually as well but nothing changed.
I was reminded by an article about the voltage rule for VTT, you have to keep the ram and VTT voltage within a 0.5 range. If you have the ram at 1.65 you have to keep the VTT voltage at 1.15.
While the above is true that was not what solved my problem because I encountered the same thing after trying another overclock. The problem was CPU-Z, the last version doesn't read my overclock correctly, I installed an older version and it displayed everything as it should.
