DTM64385F is a registered 2Gx72 memory module,
which conforms to JEDEC's DDR3, PC3-12800
standard. The assembly is Dual-Rank, with each ran
k
containing eighteen Samsung 1Gx4 DDR3-1600
SDRAMs.
One 2K-bit EEPROM is used for Serial Presence
Detect and a combination register/PLL, with Address
and Command Parity, is also used.
Both output driver strength and input termination
impedance are programmable to maintain signal
integrity on the I/O signals in a Fly-by topology.
A
thermal sensor accurately monitors the DIMM module
and can prevent exceeding the maximum operating
temperature of 95C.
