DRH2666E/16GB is an Unbuffered 2Gx72 memory module, which conforms to JEDEC's DDR4-2666, PC4-2666 standard. The assembly is Dual-Rank. Each rank is comprised of nine1Gx8 DDR4-2666 SDRAMs. One 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 in a Fly-by topology. A thermal sensor accurately monitors the DIMM module and can prevent exceeding the maximum operating temperature of 95C.- Bi-directional Differential Data Strobe signals- Per DRAM Addressability is supported- Write CRC is supported at all speed grades- DBI (Data Bus Inversion) is supported(x8 only)- CA parity (Command/Address Parity) mode is supported- Supports ECC error correction and detection- 16 internal banks- SDRAM Addressing (Row/Col/BG/BA): 16/10/2/2- Fully RoHS Compliant
