Technically none of you guys are doing this right.

There are two ways to do this.

The first is to run with the smallest amount of ram possible. This places as much data into L2 as possible keeping the CPU working at as close to maximum as possible (small FFT's).

The second is to run with as much ram used as possible to create as much stress as possible on the memory controller, chipset, and memory.

Testing both ways is preferred.
