also i just came up with another question to add onto my orig ?? neway the timings on the ocz 2gb chips is 5-5-5-15 and 1.8v, if i cant use my simm chips and i end up buying more, i cant seem to find those exact ocz chips, so i need to buy more that the timing is 5-5-5-15 or does that matter since they are going in different banks anyway? does that make since? i am pretty new to all this memory stuff.
