A-Tech 128GB DDR4 2666 ECC RDIMM Server Memory

128GB DDR4 2666 ECC RDIMM Server Memory

This A-Tech module provides 128GB of registered ECC DDR4 memory in a single 288-pin DIMM. It is built for servers and workstations that require high-density, error-correcting memory to maintain data integrity under heavy workloads. The module uses Samsung chipset and operates at 2666MHz with CL19 latency.

DDR4 2666 registered DIMM constraints

Registered DIMMs add a buffer that reduces electrical load on the memory controller, allowing higher module counts per channel than unbuffered memory. This module requires a platform that supports DDR4 RDIMM with ECC and the 2S4Rx4 (8Rx4) 3DS/TSV rank structure. Systems limited to UDIMM or lower rank counts will not accept it.

128GB single-module capacity decides fit

The 128GB density in one slot is the specification that determines whether this part suits your build. Verify that your motherboard or server lists 128GB RDIMM support per slot and the 8Rx4 rank configuration before purchase. Buyers who need lower-density modules or unbuffered memory cannot use this kit.
