I recently bought a new memory the viper 3 mamba 2133mhz.
When I activated the X.M.P profile in the bios the CPU core voltage ( I saw it using AIDA CPUID) increased alot, like 1.296v.
Then I also tried to set the memory frequency manually, but again no sucess.
What I noticed is that once I activated the X.M.P or tried to adjust it manually the CPU could not IDLE properly, with CPU frequency always set at 3.7 ghz ( once again I saw it in AIDA CPUID), giving me an average of 54ºC CPU temperature in IDLE.
