RAM Upgrade Check

[[TC]»Elmo«]

BTW, you don't need 1600MHz RAM on a Phenom II unless you overclock it; the stock memory controller runs at 1333MHz.

On the whole, any DDR3 will work, providing it's fast enough for the CPU (subject to maximum size supported by the motherboard).

FWIW, I have 2x4GB of Corsair XMS3 running nicely with my Phenom II X4 955.

You may as well get the XMS3, because the heatsink takes up much less room, so is more likely to physically fit.
