32GB DDR4 2933 ECC UDIMM for Servers

This A-Tech module delivers 32GB of DDR4 2933 (PC4-23400) ECC unbuffered memory in a single 288-pin DIMM. It targets server and workstation operators who need error-correcting capacity without registered buffering. The CL21 latency and 1.20V operation match standard DDR4 specifications for compatible platforms.

Major-brand chips on 2Rx8 unbuffered layout

Built with major-brand chipset components in a 2Rx8 configuration, the stick fits standard DDR4 DIMM slots on boards that accept ECC UDIMM modules. Unbuffered design keeps electrical loading low for consumer-derived server boards, while the 288-pin interface ensures physical compatibility with DDR4-only sockets.

Replaces Samsung M391A4G43AB1-CVF modules

This unit serves as a direct equivalent for the Samsung M391A4G43AB1-CVF part number, letting administrators expand or refresh memory in qualified systems. The jump is worthwhile when workloads demand ECC integrity at 2933 MT/s and the platform supports unbuffered DDR4 DIMMs rather than registered or load-reduced variants.

Questions about this item

What speed does the DDR4 2933 PC4-23400 interface actually run at in a system?

The module is rated for DDR4 2933 MT/s (PC4-23400). It will operate at that speed if the platform supports it; otherwise it downclocks to the highest speed the memory controller allows.

What physical slot and clearance does the 288-pin ECC UDIMM need?

It fits a standard DDR4 288-pin DIMM slot. As an unbuffered ECC UDIMM it has the same height and keying as regular DDR4 DIMMs, so no extra clearance is required beyond the slot itself.

How do I install the 32 GB 2Rx8 module and what step is often missed?

Power off, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until both retention clips click. The step often missed is confirming the system BIOS recognises the full 32 GB capacity and ECC function after boot.
