ok, so one of my dad's old co-workers asked me to look at his comp. it was having low virtual memory problems. so, for shits and giggles, i opened the thing up and looked at the memory thinking that i might have an extra stick laying around, lets see if its compatible. well, it turns out its a 256MB DDR2 400 and im like "well THERE'S your problem!"
now here's my question, the stick that i do have laying around is a 256MB DDR2 533. i already checked and the computer can handle 533mhz. if i put both sticks in to equal 512, would it be compatible at 533 or would i effectively be underclocking the 533 to 400 to get it to work?
i know the simple solution is to just buy new ram as it is dirt cheap, but its the weekend and it wouldn't ship till monday and arrive till wed/thurs had i done it.
