Make sure your motherboard will support more RAM and at the speed you expect it to run.
Windows 7, 64-bit Home Premium will support up to 16 gigs and that will be just fine (actually 8 gigs would manage well enough).
Motherboards will support the amount they say, but sometimes at a slower speed than they say or you might expect.
Ignore this strange post! DAoC runs great (with less than 8 GB RAM) on Win7 x64
