Upgrade RAM?

[kenpachi7]

Hi I have an i5 760 cpu, asus p7p55d-e and 8gb 1333mhz g-skill ram dual channel, 4 modules 2gb each, I was thinking of upgrading to 1600 mhz, I noticed my board can have 2200 (oc) ram as well, does tht essentially mean I can have 2133 mhz ram, do I need to tweak settings to get it to support, please explain fully what ram I can get for my board, and also if its worth upgrading? I currently run my cpu at 4ghz

not worth the upgrade thn best puting money towards a stronger graphics card i have gtx 465 thinking of 580gtx, i ran prime 95 it wont run more thn 10 min past 4ghz unsure if its the ram holding back.
