memory standard question

post #1 of 4
Thread Starter 
Ok so, this summer my sister has asked me to build her a computer that will run math programs like nobodies business and i had a question about memory and motherboard support. when a mother board says memory support, I.E. DDR3, does that mean you can only put the type of memory in it or can you still put DDR2 memory in it? just wondering cause DDR3 is expensive and im trying to keep the cost low. thanks in advance

DDR3 is not backwards compatible with DDR2. There are a handful of boards that will accept both, but they are few and far between.

DDR3 really shouldn't cost more than DDR2 at this point.
