I've got an Asus A8R32-MVP Deluxe board and I use Geil RAM DDR400. The problem I've got is when I put in 2GB the RAM frequency drops to 333Mhz on all 4 512MB sticks. When I have 1GB with either matched pair of 512MB sticks in it runs at 400Mhz. Has anyone seen this before? Would it be better to run on 1GB at 400Mhz or 2GB at 333Mhz? I have a 4800+ dual core AMD with 1900 XT gfx btw.
