A buddy of mine just got a free computer to put in his shop and I've been doing some work on it for him. The system itself is a Dell build but it's not too bad; he only needs it for certain things like surfing the web, listening to music/videos, ripping and burning CD's etc... I told him that he should let me upgrade the RAM since the system is lacking badly, only 256MB DDR2 (single channel). I recommended at least a gig of DDR2 since it's so inexpensive. My question is; since RAM is really not my thing, is it possible to upgrade the memory in this thing to faster dual channel modules or is he stuck with the snail RAM? I ran CPU-Z and got the specs on the RAM, 133mhz or something. I'd like to hook him up with a decent pair of PC2 4200 sticks or something but I don't know if they're compatible with the board. The system does use a socket LGA775 processor so would I be okay with any kind of DDR2 memory, single or dual channel? Any help is appreciated, thanks in advance.
