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.

Questions about this item

Will this 288-pin DDR4 RDIMM run in a server that currently uses Samsung M393A1G43DB0-CPB modules?

The module is listed as a compatible equivalent for Samsung M393A1G43DB0-CPB and M393A1G43EB1-CPB, matching DDR4 2133MHz, ECC RDIMM, 2Rx8, and 1.2V specifications.

How can I confirm the 2133MHz speed and ECC function are active after installation?

Enter the system BIOS or UEFI and verify the reported memory speed shows 2133MHz and that ECC is reported as enabled or active.

Does the package include only the 8GB module or are any cables or brackets supplied?

The product is an 8GB DDR4 288-pin RDIMM module; no cables, brackets, or additional accessories are included.
