DVM26R2T8/8G is a registered 1Gx72 memory module, which conforms to JEDEC's DDR4-2666, PC4-2666 standard. The assembly is Dual-Rank. Each rank is comprised of nine 512Mbx8 DDR4- 2666 SDRAMs. One 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.
