Our testing has been split into four different stages.

First up is what we are calling "general performance" which looks at triple-channel DDR3 memory operating at 800/1066/1333 and 1600MHz using native timings for performance modules. Then we are moving on to frequency testing which looks at the same clock speeds but using the same CAS9-9-9-20 timings for all four configurations.

This is followed by our "latency performance" tests where we take a triple-channel DDR3-1066 configuration and test it four times using four different sets of timings ranging from CAS7-7-7-20 to CAS10-10-10-20.

Our last test configuration has been titled "channel performance" and here we look at the effects using single, dual, and triple-channel memory with the Core i7 processors. This test also factors into account the difference between 2GB, 4GB, and 6GB of DDR3 memory as well.
