It seems like DDR3 RAM hasn’t been around that long in desktop machines and now it is starting to show up in new laptops. DDR3 offers higher operating frequencies promising more performance. However, the drawback is that the latencies on DDR3 are typically much higher than on DDR2 parts negating some of the performance gains.
Kingston has announced that it is now shipping its HyperX DDR3 ultra-low latency SO-DIMM RAM for notebooks. The new RAM operates at 1066MHz and is pre-programmed for high-performance and low latency values. The RAM also has a new metal heat spreader to help reduce heat build-up in the memory.
