TwinX2 PC4300 DDR2 Available from Corsair

"DDR2, the second generation of Double Data Rate memory technology, includes new features such as a larger 4-bit prefetch and programmable on-die termination (ODT) to reduce signal bounce and improve reliability at high speeds.

"This product is among the first and the fastest DDR2 modules in the world. It was designed specifically for gamers, overclockers and enthusiasts who demand exceptional performance" said Corsair President Andy Paul."
Not really "Low Latency" but exciting at any rate.
