hey guys
i already have 3x 2GB xms3 Corsair 2000mhz installed on PC and i got 3 slots left to upgrade.
Can i add 2x 4GB xms3 corsair 2000mhz to it ? both DDR3
i dont know if you are going to need extra info or not, so i'll just write it down :
motherboard : Gigabyte X58A-UD3R
Proccessor : Intel core i7 950
GPU : AMD 6870

one more thing that would be nice to know is why is it say 2000mhz on my Ram but shows 2157 in CPU-z ?
