Bandwidth and latency analysis
| ScienceMark 2.0 memory bandwidth | |||
|---|---|---|---|
| G.Skill 2GB DDR3-1600MHz | Corsair 4GB DDR3-1,600MHz | Crucial 2GB DDR3-2,000MHz | Corsair 4GB DDR2-1,066MHz |
| 8466.47 | 8008.59 | 8293.1 | 7536.82 |

| 8999 | 8564 | 8832 | 8399 |
Memory bandwidth is a little low when compared to the other two DDR3 comparison modules, but higher than slower-speed DDR2. The Corsair set is running comparatively high (slow) timings and these may well be the cause.

| G.Skill 2GB DDR3-1600MHz | Corsair 4GB DDR3-1,600MHz | Crucial 2GB DDR3-2,000MHz | Corsair 4GB DDR2-1,066MHz |

| CPU-Z memory latency | |||
|---|---|---|---|
| G.Skill 2GB DDR3-1600MHz | Corsair 4GB DDR3-1,600MHz | Crucial 2GB DDR3-2,000MHz | Corsair 4GB DDR2-1,066MHz |
| 48.02 | 53.65 | 47.4 | 53.23 |
Latency, too, isn't the hottest, kind of matching the DDR2 set which runs with 5-5-5-15 timings at 800MHz.
