4GB DDR3 1866 ECC Registered Server Memory

This A-Tech module delivers 4GB of DDR3 1866 (PC3-14900) capacity in a 240-pin ECC RDIMM format. It operates at 1.5V with CL13 latency and uses a 1Rx8 registered configuration built with major brand chips. The module is designed as a compatible replacement for the Samsung M393B5173QH0-CMA part number.

Suits servers and workstations requiring

This module fits systems that specifically support DDR3 1866 registered DIMMs with ECC error correction. Buyers needing unbuffered UDIMM memory, higher density modules, or different voltage requirements should look elsewhere. Verify your platform's qualified vendor list before purchasing to ensure compatibility.

Registered ECC RDIMM form factor determines

The 240-pin registered DIMM design with on-board register and ECC functionality only works in motherboards wired for registered memory. Consumer desktop boards that accept only unbuffered UDIMMs cannot use this module. Confirm your system requires registered ECC DDR3 before ordering.

Preguntas sobre este artículo

How can I verify the module is running at DDR3 1866 CL13 after installation?

Check the BIOS or a tool such as CPU-Z; the memory tab should show 1866 MT/s and CAS latency 13 at 1.50 V for this registered ECC DIMM.

What ships with the module and is anything else required?

The package contains one 4 GB DDR3 1866 ECC RDIMM; no extra parts are needed if your server has a free 240-pin registered DIMM slot.

Should I choose the 1Rx8 4 GB stick or look for a different capacity?

Select this 1Rx8 4 GB module when your system requires a single-rank registered ECC DIMM at 1866 MHz; match the rank and voltage to your platform's qualified-vendor list.
