The Nexus DDR2 SODIMM slot interposers allows for logic analyzer acquisition of Address/Command, Read and Write Data of 200-pin Unbuffered SODIMMS.
This ASRock board supports both DDR2 and DDR3 memory dimms. There are four DDR2 dimm slots which support up to 8GB at speeds of 1066/800/667. DDR3 support includes up to 4GB in the two dimm slots that are available. DDR3 support is for speeds of 1333/1066 and 800. Just as a note, you cannot use both DDR2 and DDR3 at the same time. This is a pretty nice feature of this board, and makes for a nice upgrade path once the price of DDR3 memory comes down to a reasonable price. Until then, you will have no issues using the DDR2 slots.
