DTM68127-His a registered 1Gx72 memory module, which conforms to JEDEC'sPC4-2666standard. The assembly is Single-Rank with arank containing: nineMicron1Gbx8DDR4-2666SDRAMs. One 4K-bit EEPROM is used for Serial Presence Detect and a combination register/PLL, with Address and Command Parityis 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.
