PROBLEM : why my CPUZ shows 'max bandwidth' at 667MHz only. should hav been 800MHz right even though BIOS set it to 667Mhz right? (since it's the 1600Mhz written on product should be the Max)
The default speed for your CPU is 1333MHz, so 667 is correct.
1. not gonna overclock my RAM since it will increase the voltage. or should i?
2. just want it to be optimized to it's normal speed.
3. what is XMP actually?
4. how do i read the memory timing?
5. what is really my RAM normal voltage 1.50V or 1.65V? (non exact model on latest QVL)
The XMP is preset overclock profile of the RAM in the RAM stick. U need to enable the XMP in the BIOS and it will run @ 1600MHz.
U also need RAM that is 1.5V
