A-Tech 512GB (4x128GB) DDR5 5600 EC8 RDIMM 2S2Rx4 Server RAM

Server Memory Kit

This A-Tech 512GB kit contains four 128GB DDR5 modules built for servers and workstations that require registered ECC memory. It is not compatible with desktop or laptop computers. The quad-channel kit delivers 512GB total capacity for multi-socket platforms that support high-density DDR5 RDIMMs. Buyers who need unbuffered memory or consumer form factors cannot use this product.

Registered ECC with 3DS Stacking

Each module is a 288-pin DDR5 RDIMM organised as 2S2Rx4 quad-rank using 3DS/TSV stacking. The EC8 registered ECC design provides error correction and signal buffering required by server chipsets. Systems that do not support registered ECC or quad-rank 3DS modules will not accept this memory. Buyers whose platforms require single-rank or dual-rank unbuffered DIMMs must choose a different kit.

512GB Capacity at DDR5 5600

The kit operates at 5600 MT/s with CL46 latency at the standard 1.10V DDR5 voltage. Four modules populate four channels for maximum bandwidth in compatible multi-processor servers. Workloads that exceed 512GB or require speeds above 5600 MT/s will need additional modules or a faster memory tier. Systems limited to lower densities per slot or slower DDR5 speeds cannot utilise the full specification.
