Actually, 1 gig is enough memory. Why you would need more I do not know. Also, unless your overclcoking, anything above pc3200 is overkill. In response to your other question, any ram with timing of 2-2-2-5 is good ram for athlon 64. The pc-3700,4000 is just to give more headroom for overclocking while keeping a 1:1 ratio.
yes i understand that lol the reason i want it beacause i "am" over clocking but ur right ( other reason is i have really cheap ram right now lol ) i want to oc my 3400+ to at least 2.37 ish i hope and also iono wuh i could do to my fx5200
