ADATA continues to lead the industry in DRAM timing and density with these 8GB Premier Series DDR3 1600 single piece memory modules. They are designed and engineered to support the ever more rigorous requirements of enthusiasts and professionals. The high 8 GB density overcomes situations where there are only a few DRAM slots on the motherboard, allowing users to maximize system potential and performance.Meets Rigorous Standards and SpecificationsThe Premier Series 1600 Mbps DDR3 204-Pin (SO-DIMM) are standard pin design modules operating at 1.5 volts, with transmission bandwidth up to 12.8 Gb/second (PC3 12800). The memory modules implement cutting edge technology that enables remarkable memory density on a single module. All the modules are in accordance with JEDEC (Joint Electron Device Engineering Council, JEDEC Solid State Technology Association) and RoHS design and production standards, simultaneously ensuring compatibility with all the computer systems adopting the same standard and ecologically sound product. ADATA Series memory modules come with lifetime warranty and service, providing remarkable protection.Model name AD3S1600W4G11-2Series PremierCapacity 8 GB (2 x 4096 MB)Module amount 2 piecesplacement two-sidedmemory chips amount 32 (16per module)data density 4096 each memory chiporganisation 512Mx8Design SO-DIMMType DDR3Connection 204-PinVoltage by 1.425 Voltage until 1.575 VoltageStandard DDR3-1600 (PC3-12800)TimingsCAS latency (CL) 11RoHS Compliant Yes
