I got an older hp sff computer I've upgraded for a friend of mine to use. It still runs DDR2 with a core 2 quad. I got 4gb of ram in it but obviously this is not nearly enough for him and he wants more. I was recently given an old laptop with a 4gb stick of DDR2 SODIMM memory. My question is, if both the ram already in the HP computer he has and this laptop memory is the same speed, could I get a DDR2 SODIMM to DIMM adapter to allow it to run in dual channel, as in, 3 1gb sticks and the 4gb SODIMM stick? Any info would help!
