The upcoming Intel Bearlake-X chipset which will be launched within a year will feature support for DDR3 memory:
Intel has been using DDR2 for a while and in the third quarter next year it wants to add support for DDR3 to these new chipsets.
The chipset will be paired with the ICH9 family south bridge in ICH9R and IHC9DH flavours.
The chipset Bearlake-X will have support for PCIe 2.0, 2x16X PCIe graphics, DDR3 running at 1333 speed, Quad core support. This chipset will follow after announcement of Bearlake-P and Bearlake-G chipsets in Q2 2007. The key difference is that the first Bearlake won't have as many features as the Bearlake-X and G+ especially the DDR 3 support.
