16GB DDR5 ECC UDIMM for workstations

This 16GB DDR5 4800 module delivers error-correcting code memory in an unbuffered 288-pin UDIMM form factor. It operates at 1.1V with CL40 latency and conforms to JEDEC PC5-38400 specifications. The stick is built for desktop workstations, servers and NAS systems that require data integrity without registered buffering.

Replaces Samsung M324R2GA3BB0-CQK when ECC is needed

The module is a direct replacement for the Samsung M324R2GA3BB0-CQK part, matching its DDR5 4800 speed, 1Rx8 organisation and 1.1V voltage. The upgrade is worth it when a system demands ECC unbuffered memory for silent data-corruption protection in always-on workloads. Compatibility extends to desktop, all-in-one, workstation and NAS platforms that accept standard UDIMMs.

Suits ECC-capable workstations and NAS units

This memory suits administrators who need 16GB of validated ECC unbuffered DDR5 for file servers, ZFS arrays or virtualisation hosts. It is not intended for consumer gaming boards that lack ECC support in the CPU or chipset, nor for systems requiring registered or load-reduced DIMMs. Buyers should verify motherboard ECC support before purchase.

Questions about this item

Will the 288-pin DDR5 module fit my workstation DIMM slots?

The module uses the standard 288-pin DDR5 UDIMM form factor at 1.1V, matching JEDEC specifications for desktop, workstation, NAS and server boards that accept DDR5 ECC unbuffered memory.

What is the correct way to seat the 1Rx8 stick so the system recognises the full 16GB?

Align the notch with the slot key, press straight down until both retention clips click, then verify in BIOS that the module reports 4800 MT/s CL40 at 1.1V with ECC active.

When should I plan to replace the Samsung M324R2GA3BB0-CQK compatible DRAM?

DDR5 ECC unbuffered modules have no scheduled replacement interval; swap only if memory diagnostics report correctable errors rising or the system fails POST with this stick installed.
