Virtual-Hideout posted a review on the Mushkin 2GB HP2-6400 DDR2-800 Memory

The quality of memory used in this particular HP2-6400 kit is evident by the superb overclocking potential. Obtaining 1000mhz from an 800mhz kit is proof these are indeed high performance memory modules. Add to that the good looking blue aluminum "FrostByte" heatspreaders and you've got a potent combination.
