I currently have 4 modules of 512MB DDR400 Corsair Valueselect memory in my computer, running with my socket 939 AMD Athlon 64 3500+ and nForce 4 chipset. The command rate is currently set to 2T and the modules are running at DDR400 speeds. Please help me with my dilemna: should I take out 1 or 2 modules or should I leave all 4 in? Which would give me greater performance, namely in games?
