8GB DDR3 1866MHz ECC RDIMM Server Module

This A-Tech module is an 8GB DDR3 1866MHz ECC Registered DIMM built for server and workstation systems. It uses a 1Rx4 configuration with Samsung chipset and operates at the standard 1.50V voltage. The 240-pin DIMM is a compatible replacement for the Samsung M392B1G70DB0-CMA part.

Suited for registered ECC slots only

This memory fits systems that require DDR3 ECC Registered DIMMs with a 1Rx4 organisation. It will not work in desktop boards that accept only unbuffered non-ECC modules. Buyers needing higher capacities per slot or different rank configurations should verify their platform specifications first.

1Rx4 registered ECC organisation

The single-rank by four-bit arrangement determines compatibility with specific server memory controllers. Systems requiring dual-rank modules or unbuffered ECC will not accept this DIMM. Confirm the 1Rx4 requirement in your hardware manual before ordering.

Questions about this item

Will this DDR3 1866 MHz ECC RDIMM operate at its rated speed alongside slower registered DDR3 modules already installed?

The module runs at 1866 MHz with CL13 timing at 1.5 V; the system memory controller will set a common speed for all populated slots.

How can I verify the 1Rx4 registered ECC module is recognised and functioning after installation?

Check the BIOS memory summary for 8 GB at 1866 MHz, ECC enabled and registered status, then run a memory diagnostic such as MemTest86.

Does the 240-pin DDR3 DIMM ship alone or with any accessories or tools?

The box contains the single 8 GB DDR3 1866 MHz ECC RDIMM module only; no cables, brackets or tools are included.
