Kingston Hyper-X DDR2 675MHz PC2-5400 Review
 

Quote: "Kingston’s Hyper-X line of RAM has always been favored by
overclockers and gamers alike. The modules are stable and run fast.
Well, the Hyper-X line has finally made the jump to DDR2 and Buddha’s
got some most excellent results to share with y’all."
