The X38 chipset will be able to support DDR2 as well although Intel did not list that down officially on their roadmap. Amid sky high prices of the DDR3 memories currently, it seems it is a logical choice to stick to the much cheaper DDR2 memories. Of course, the LANPARTY X38-T3R board that supports DDR3 memories will come later. LANPARTY X38-T2R/T3R board supports 1333FSB Core 2 Duo and Quad processors, two x16 PCIe slots for dual graphics + one x4 for physical, 8-Phase Digital PWM, special heatpipe cooling for PWM, MCH and ICH.
