Apacer Technology Inc. 8GB ECC DDR4 SDRAM UDIMM Memory Module

Apacer Technology Inc. 8GB ECC DDR4 SDRAM Memory Module is a 1024M x 72 DDR4 SDRAM (Synchronous DRAM) ECC DIMM. The D32.27245S.002 SDRAM, high-density memory module, consists of 9 pieces 1024M x 8-bits DDR4 synchronous DRAMs in FBGA packages and a 4K Bits EEPROM. The Apacer 8GB, ECC DDR4 SDRAM, offers 288-pins dual in-line memory designed for mounting into a connector socket.
