Wasn't the idea at a time to use the 2nd card as a physics engine?

@cereal - dude AFAIK dual channel will run with all 4 slots filled(otherwise why are there 4 slots)

It is optimal to have matching RAM, but should work without at the timings of the slowest memory.

I may be wrong....

You can run 2x512MB memory modules with 2x1GB in the other two slots, as long as they match.

i.e: If your 512's are 800Mhz DDRII CL5 then the 1Gb's need to be the same.

Know for a fact this setup does work, reports at 3Gb's in window and no bottlenecks.
