call a rep on the phone from amd, running outside the 1333 spec is not supported by the memory controller, and they cant help you if you decide to go beyond that. had that talk with them over the phone when my c2 stepping phenom's memory controller bit the big one. may not void the warranty, but its definately not supported by amd and i dont recommend it either, hence why now the new bulldozer chips are upping the memory controller limits to 1866 speed.
tho im still not sure why its suggested that he gets fast ram when the cpu will be the biggest potential bottleneck here, due to lack of cores, tho im not sure what chip he went with at this point.
Wait lemme get this straight.... I want to go with the 1600 regardless if they run at 1333 because then there is room for improvement if I overclock and there's a higher resale value?
