Mushkin 1Gb PC4400 Hi performance dual memory
 

This ram overclocks well so you will have fun for a long time while tweaking this ram to the max. Remember though just because we were able to get this you might get even higher or lower all depending on your computers parts etc.

275 FSB 2,5-3-3-8
300 FSB x7 2,5-4-4-8
330 FSB x7 2,5-4-4-8
Red&Blackness gives it 5 out of 5 dots
