i am running 512mb of mwave brand memory on my amd 64 3000+, asus k8n, system. the memory runs at 2.5 cas and seems to be ok. my question is, i want to get up to a gig of memory and would you recommend just getting another stick of 512 mb (because i have 2x256 right now) of mwave memory, or should i get a different make of memory, or switch competely?
