The Adata 4GB DDR3 1333MHz Desktop Ram module is a 512Mx72 bits 4GB(4096MB) DDR3-1333(CL9)-9-9-24 SDRAM memory module. The SPD is programmed to JEDEC standard latency 1333Mbps timing of 9-9-9-24 at 1.35V. Adata 4GB DDR3 1333MHz module is composed of eighteen 256Mx8 bits CMOS DDR3 SDRAMs in FBGA package and one 2Kbit EEPROM in 8pin TDFN package on a 240pin glass–epoxy printed circuit board. Adata 4GB DDR3 1333MHz module is a Dual In-line Memory Module and intended for mounting onto 240-pin edge connector sockets. Synchronous design allows precise cycle control with the use of the system clock. Data I/O transactions are possible on both edges of DQS. The range of operating frequencies, programmable latencies, and burst lengths allows the same device to be useful for a variety of high-bandwidth, high-performance memory system applications.
