General Description
Apacer
78.D1GMP.4010B
is a 2048M x 72 DDR4 SDRAM (Synchronous
DRAM) ECC Registered DIMM. This high-density memory module consists of
18 pieces 1024M x 8 bits with 4 banks DDR4 synchronous DRAMs in FBGA
packages and a 4K Bits EEPROM. The module is a 288-pins dual in-line
memory module and is intended for mounting into a connector socket. The
following provides general specifications of this module.
