Server ECC RDIMM for workstations

This A-Tech module is an 8 GB DDR4 registered DIMM built for server and workstation platforms that require error-correcting memory. The registered buffer reduces electrical load on the memory controller, allowing larger configurations in multi-socket boards. It targets administrators upgrading or repairing systems that specify DDR4 2133 ECC RDIMM parts.

8 GB capacity at DDR4 2133 CL15

The single rank 2Rx8 stick delivers 8 GB of addressable space, suited to typical virtualization hosts, database nodes or compute nodes running moderate workloads. At 2133 MT/s with CAS latency 15 it matches the JEDEC PC4-17000 baseline, so it will not accelerate workloads beyond that speed tier. Systems needing higher bandwidth or larger per-module density will hit the ceiling of this specification.

288-pin registered build with major-brand chips

The module uses a standard 288-pin DDR4 DIMM form factor and operates at the DDR4 standard 1.20 V. Major-brand DRAM components are assembled on a registered PCB, ensuring signal integrity in populated channels. The RDIMM keying prevents insertion into unbuffered consumer slots, so the part only fits platforms designed for registered ECC memory.
