What memory

Best would be Memory: 1GB Corsair TwinX Paired DDR PC3200 RAM or the Pro version for lower latency if reused without other pair or in another rig.
You could also try other cheaper brands, but a little (not much) risk of incompatibility.

I have the Gigabyte 8KNXP Ultra-64 board and Prescott 3200 with 4-512MB Corsair XMS Pro 2-2-2-5 memory.

You can mix the lower latency with higher latency with no problem.

3 sticks won't work in dual channel, so get the matched pair.

I like the LED lites, of course I have a clear panel.
