Crucial Ballistix DDR3 1600mhz
 

The interest surrounding DDR3 RAM modules is slowly growing. While prices are still high, the technology has advanced quite quickly and the performance of the modules has significantly improved.

Although many of the high performance DDR3 chips are currently made by Micron, ironically Crucial began offering high speed DDR3 modules a few months later than other companies. Today we will take a look at the best DDR3 set Crucial currently offer, the Ballistix PC3-12800 2GB kit. Rated at 1600MHz with 8-8-8-24 timings @ 1.8V they should offer excellent performance.

the way things currently are, even 5000Mhz DDR3 would not boost Core 2 performance noticeably...
