Your mobo can run 1333 in a 2x4GB config, if you OC the FSB (this will also OC your CPU, so be prepared to lower the multiplier if t runs too hot), will likely need additional voltgae to vCore, DRAM and NB.... would look for a 2x4GB 1333/9 set, the GSkill Ripjaws might be good fit , or their Sniper line
