Each DRH1600UN upgrade consists of a single DDR3-1600 Unbuffered Non-ECC DIMM that conforms to JEDEC's DDR3, PC3-12800 standard. One 2K-bit EEPROM is used for Serial Presence Detect. Both output driver strength and input termination impedance are programmable to maintain signal integrity on the I/O signals.
