Question about memory timings.

My Rig:

M4A785TD-M EVO

Athlon x4 with a mild overclock to 3.3GHz with HyperTX cooler.

GTX 260 OC edition (655mhz)

6GB G.skillDDR3 at 1333mhz

Raidmax 80 Plus certified 630W Power Supply

My question is, my RAM I bought was 1600. The defualt setting for my mobo is 1333. Will I see much of a difference if I set the ram to 1600? And if so, could someone give me some tips to set it to 1600?

not even God himself could tell the difference with those speeds

It is unlikely that you would notice a difference.
