The Corsair CM2X512-8000UL modules reported excellent performance in our benchmark tests. The results were good at 667MHz and 800MHz, but at 1000MHz they were excellent. Corsair reaches the highest levels of performance without any compromise in timings. The highest speed of 1000MHz, was attained with the lower timings, in comparison to those at 667MHz and 800MHz with SPD.

SiSoft Sandra 2005 reported the very high score of 7602MB/s and 7619MB/s in RAM Bandwidth Integer and Floating Point respectively, while in Combined Index, the reported 13620MB/s is the highest we have seen. The high performance was also confirmed in PCMark04, with the score reaching 7636.0 PCMarks while with Performance Test v5.0, it was 631.9. In games, the increased memory speed in combination with the overclocked CPU can raise the frame rate, as happened in our HL2 test where we saw a jump of approximately 20fps when going from 667MHz to 1000MHz. And all this while Memtest86+ confirmed that at 1000MHz with 5-4-4-9 timings, operation was error free.

If you want the fastest DDR2 memory that you can buy for Intel CPU based boards, Corsair should be your choice. The retail price for the Corsair CM2X512-8000UL is close to $267 from newegg.com. Although the price sounds a little expensive, we believe that it is worth the money, especially considering the 1000MHz!

The Good:
- Excellent performance at all speeds
- Stable performance even at 1000MHz
- Can handle Voltage up to ~2.2V without problems
- Stylish design with the black heat spreaders

The Bad:
;-)
