Ive got an AMD athlon 64 3500 and what i assume to be a not so great motherboard (gigabyte k8ns ultra-939) i have 2 different brands of memory, and i know its a good idea to go with a matched pair. one stick of 512 i picked up cheap at compusa when i was first putting it together, so im sure it sucks. im completely confused about overclocking because the OCing utility that came with the board sucks and i dont know how to do it thru bios yet. but im out to learn. so i need to upgrade and i was wondering what peoples suggestions are. i just got a new antec 480watt true blue powersuppy from compusa that i can return cause i got a friend who works there and she always hooks me up. thought that might be of some importance for building major overclocking. anyhoo, lets hear what yall think.
