DDR DIMM Slots
(DDR 1~2)
Introduction to DDR SDRAM
DDR (Double Data Rate) SDRAM is similar to conventional SDRAM, but doubles the
rate by transferring data twice per cycle. It uses 2.5 volts as opposed to 3.3 volts
used in SDR SDRAM, and requires 184-pin DIMM modules rather than 168-pin DIMM
modules used by SDR SDRAM.
