8GB DDR4 2133MHz ECC RDIMM

This A-Tech module is an 8GB DDR4 2133MHz ECC registered DIMM built with Samsung chips. It targets server and workstation administrators who need a verified replacement for the Samsung M393A1K43BB0-CPB part number. The single-rank 1Rx8 organisation and 1.20V operation match the original specification.

Suits ECC registered platforms only

It fits systems that require DDR4 ECC RDIMM memory with a 288-pin interface and CL15 timing. Builders using consumer desktop boards that accept only unbuffered non-ECC DIMMs cannot use this module. Laptop or small-form-factor owners needing SO-DIMM modules should also look elsewhere.

Registered ECC with 1Rx8 organisation

The registered buffer and ECC capability are the decisive attributes; the module will not function in platforms that demand unbuffered memory or lack ECC support. Confirm the motherboard qualification list for this exact part number before ordering.

Perguntas sobre este artigo

How do I install this 288-pin DDR4 RDIMM and what step is often missed?

Align the notch on the module with the key in the server DIMM slot, press down firmly until both side clips click shut, then confirm the system registers the full 8GB capacity at 2133MHz in BIOS or the OS memory report.

What maintenance or replacement will this ECC RDIMM need over its service life?

No routine maintenance is required; the module is validated for continuous server operation and should only be replaced if memory diagnostics report uncorrectable ECC errors or the system fails to POST with the DIMM seated.

What limit appears first when this 1.20V 1Rx8 module runs under sustained load?

The DDR4 2133MHz CL15 timing and single-rank 1Rx8 organisation set the bandwidth ceiling, so sustained throughput tops out at the PC4-17000 rating before voltage or thermal constraints become factors.
