Looks like Kingston is working to eliminate the memory bandwidth bottleneck in laptops. These new HyperX PC2-6400 CL4 SO-DIMMS jump up from 667MHz to 800MHz and work at extra low latency, bringing them up to speed with the newest P45/Centrino 2 combo setups. If you want to replace your stock RAM it’ll be expensive, though: $257 for 4GB. If my laptop were my only computer, I might consider it a worthwhile investment, but it’s beyond the point of upgrading “just because.” At any rate, it’s Kingston hardware so you know it’s going to be solid.
