I'm planning to buy 2x4GB strips of DDR3 RAM at 1600MHz 9-9-9-27 (see here) The box that it is going in will be used to run virtual machines. This means that I may want to stick another 8Gb in it at some point.
I was wondering if I could get another two strips of RAM at some point and they would still play nicely together in dual channel mode. Do I have to buy the same make and model or just something very similar? Which factors are most important?
with as many problems as people have with ram, you should at least try to get stuff that is as similar as possible. The controller it uses the configuration of the chips more important to similarity. The cute numbers actually not being AS critical as long as you manually control all that stuff yourself. which can go beyond the first 4 timing settings. – Psycogeek – 2011-10-26T23:39:03.227
