Hello there, I was using a pair of samsung 256mb with CL2.5 for few years ago (running dual channel). But I just bought a pair of Kingston HyperX 512mb x 2 which has a CL2. Do you guy think should I remove those samsung 256mb x 2, and leave the system with 1GB ram? or should I also add the samsung 256x2 in the system? ( I read there is a thread talking about not to put a slow pairs of Ram together with a fast pairs, boz it will bring the performance down). But I think 1.5gb is better than 1.0gb right?..Hmm, so I was confused. which way should I go ( P.S I dont want to buy one more pair of 512mb x2 ..boz I just dont have the money...) Thank you
