Hello,
I have a ASUS M4A89GTD PRO/USB3 with AMD Phenom II X6 1090T (not overclocked) and A-DATA Xtreme Series XPG 1600X 2GB*2 (1600 Mhz). I want to run them at 1600 Mhz and so I set them DRAM Frequency in the BIOS from auto to manual 1600 Mhz. But when I see the DRAM Frequency in CPU-Z, it shows 800 Mhz and when in the BIOS, I set the frequency to 1333 Mhz or put it in auto mode which takes 1333 Mhz, it shows 667 Mhz. I am totally new to this and have just made my new pc.

Please help me. Specs

The memory is reading right you have to multiply the memory by 2 in cpuz. Cpu-z shows you the clock speed not the actual Frequency so 800x2=1600 and 667x2=1333.
If the memory was actualy running at 800 it would read as 400 or 667 would read as 333. Hope this helps.
