yeah, Corsair doesn't overclock very well.
if you do buy better RAM for it, get either G.Skill with Samsung TCCD's, OCZ or PQI (OCZ and PQI use Samsung TCCD's, and the same type of PCB's)
G.Skill is the best for overclocking. OCZ and PQI are next
the G.SKills will defintely go up the 270 you can just buy some G.skill DDR600 and run at 300x10 right off the bat. then i wuold say OCZ can get up around the 250-280 range
pqi is just dump to me, i dont know pqi really.
EDIT: please dont tell me your OCing whats in your sig....corsair valueselect, and your trying to OC with that............:laughing:
Haha, no no, don't worry. There no way I'm going to overclock with that. Thats why I was asking which memory would be best, because I'm planning to buy OC'ing memory soon.
