I read yours, but you probably did read or think about what you wrote:
To which I replied:The ram the OP has in his old pc is most likely DDR2
We can go back and forth all day on this I think your trying to argue that I don't get your reasoning and I was merely expanding on the point missed by a few people that he was replacing the ram and not adding it. Merely stating that his old ram is likely DDR2 will only confuse people further to the mix and match reasoning made earlier in this thread.Which he said he would be replacing.
