From 256MB to 1GB in size, Kingston is now manufacturing DD2-667 RAM for Notebook computers. Running at 1.8V, even the very fast 333MHz RAM uses less power than traditional DDR, and offers “up to” 6.4GB/sec transfer rates. Despite the high latency, RAM at this speed would be very beneficial, even moreso on notebooks where often RAM quality and speed is sacrificed in lieu of other things. The modules start at a very reasonable $58 for 256MB and $87 for 512MB versions. There are some laptops on the market already that would be able to handle DDR2-667 RAM, though at the moment they are few and far in between. Soon we will probably see laptops with faster RAM than the average desktop, another sign of their quick adoption.
