Right. Im thinking of selling off my odd arangement of 4*512mb sticks, Two OCZ premier and two kingston value, and replacing them with 2 high rated 1gb sticks. I've found some very tempting looking G.Skill HZ PC4000 for a good price. Is this stuff any good? Or am i better of sepnding a little more and getting plain XMS from scan rated at the same speed?
