Last friday I built my athlon 64 3400+ system(v8t800 chipset, gigabyte board, 1.5GB of mushkin ddr433) and benchmarked it. My memory bandwith was somewhere around 3.2GBPS in Sandra and now I am showing 1.7GBPS! The problem is not in sandra as I reformatted my HD yesterday and had to reinstall Sandra. My pcmark 04 score is 3434, which is about 1000 points lower than it should be too. Any ideas on why I only have 1/2 of the memory bandwidth I should?

i dont know much about amd stuff, but it sounds like u put in 3 512 sticks of ram.i always thought to run in dual channel u have to run matched pairs (2 or 4) if so wouldnt that knock u out of dual channel and the motherboard only run at single channel?

if the mb slows down with a third stick, maybe a bios issue? sounds like its reconizing it as a much slower stick than the other 2 and running all 3 at that speed.
