Bandwidth, latency, and HEXUS.PiFast

| Corsair DDR3-1,866 CL9 6GB DOM | Crucial DDR3-1,600 Tracer 6GB | Crucial DDR3-1,066 CL7 6GB | Crucial DDR3-1,333 CL9 3GB |
| 30.64 | 26.88 | 20.02 | 19.86 |
Bandwidth scales reasonably linearly with frequency, although capacity does make a difference - take a look at the 3GB DDR3-1,333 and 6GB DDR3-1,066 results.

| Corsair DDR3-1,866 CL9 6GB DOM | Crucial DDR3-1,600 Tracer 6GB | Crucial DDR3-1,066 CL7 6GB | Crucial DDR3-1,333 CL9 3GB |
| 30.65 | 30.07 | 35.4 | 36.03 |
Latency, too, is pretty good from the 1,600 CL8 pack.

| 27.41 | 27.5 | 27.71 | 27.63 |
But put it together and there's literally no difference in the benchmark results of our number-crunching HEXUS.PiFast test - a lament that we'd had before when talking about high-speed DDR3 memory.
