Target server upgrade

This A-Tech module is an 8 GB DDR4 3200 ECC registered DIMM built for server and workstation platforms that require error-correcting memory. It replaces Samsung M393A1K43DB1-CWE and M393A1K43DB2-CWE modules in compatible systems.

Straightforward installation

The 288-pin DIMM seats in standard DDR4 registered DIMM slots and runs at the standard 1.20 V. Verify that your motherboard supports ECC registered memory and the 1Rx8 rank configuration before purchase, as consumer boards often lack the required chipset support.

Steady under sustained load

ECC circuitry detects and corrects single-bit errors during continuous operation, helping maintain data integrity in long-running workloads. The CL22 latency and 1.2 V rating keep power draw consistent across extended sessions in multi-module arrays.

Questions about this item

How can I confirm the module is running at DDR4 3200 with CL22 after installation?

Check the memory speed and timings in the BIOS or a tool such as CPU-Z; they should show DDR4 3200 (PC4-25600) and CAS latency 22 when the module is seated correctly.

What comes in the package and what must I source separately?

The box contains one 8 GB DDR4 288-pin ECC RDIMM; no cables, brackets or additional components are included.

Should I choose this 1Rx8 registered ECC version or a different rank for my server?

Select this 1Rx8 registered ECC module if your system requires registered DIMMs with ECC; verify the motherboard manual for supported rank configurations before purchasing.
