Overview: The JESD79-5 DDR5 SDRAM specification has significant improvements in capacity, speed, and voltage. By structure-wise, the Power Management IC (PMIC) is moved onto the DIMM, reducing redundant power management circuitry on the motherboard for unused DIMM slots in previous generations. The DDR5 specification brings the maximum potential capacity for a single DDR5 DIMM to 128GB, a theoretical maximum transfer speed of 6400MT/s which is doubling the rate of DDR4, along with the improved power consumption as 1.1V. The modules comply with all relevant JEDEC standards and are available in 16GB and 32GB capacities, as 4800MT/s. Specification: high capacity and speed (maximum potential up to 128GB & 6400MT/s)small outline dual In-line memory module, fully tested and optimized for stability and performance, uses original IC to meet strict industrial standards, on module power management IC (JEDEC standard: 1.1V). Operating environment: -40°C - 95°C (Tc) anti-sulfuration protection against harsh environment sRoHS compliance CE/FCC certification.
