Thx for the replys. LePaul, ive still got about 6 months before i hit my annual upgrade 8) , just thinking the extra gig might get me alittle farther down the road hehe . Hajo , i ended up ordering Corsair Xms again, went with 2X1gig c2 pro . Ive always had good luck with corsair , one of my current sticks is almost 2 years old, and has been ran overclocked its whole life 8) .My 3700 also has a 1mb l2 cache , but im waiting to see how long it will hold out being clocked at 3ghz . So far so good . 38
