The ADATAโs module is a 1024Mx72 bits 8GB(8192MB) DDR3-1600(CL11)-11-11-28 SDRAM memory module. The SPD is programmed to JEDEC standard latency 1600Mbps timing of 11-11-11-28 at 1.35V. The module is composed of eight-teen 512Mx8 bits CMOS DDR3 SDRAMs in FBGA package and one 2Kbit EEPROM in 8pin TDFN package on a 240pin glassโepoxy printed circuit board.
