Dataram DTM68308-H memory module 128 GB 1 x 128 GB DDR4 2666 MHz ECC

DTM68308-H is a load reduced 16Gx72 memory module, which conforms to JEDEC's DDR4-2666V, PC4-2666V standard. The assembly is Eight-Rank containing – thirty-six Hynix 8Gbx4 DDR4-2666V 4H TSV SDRAMs. One 4K-bit EEPROM is used for Serial Presence Detect and a Registering Clock Driver, with Address and Command Parity, is also used as well as data buffers to reduce the overall loading on the data bus. 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.
