4GB DDR4 2133 ECC UDIMM for servers

This 4GB DDR4 2133 ECC UDIMM module targets administrators upgrading compatible Micron MTA9ASF51272AZ-2G1 slots in server and workstation platforms. The unbuffered design with 1Rx8 organisation suits systems that require error-correcting memory without registered signalling. It operates at the standard DDR4 voltage of 1.20V and carries a CL15 latency rating.

Sustained load behaviour with ECC active

Under continuous workloads the ECC logic detects and corrects single-bit errors in real time, preventing silent data corruption during long compute runs or virtualisation tasks. The major-brand chipset and 1.20V operation keep power draw stable, while the CL15 timing maintains consistent throughput without the latency spikes that can appear on lower-grade modules during extended stress.

288-pin installation and common fitment issues

The 288-pin DIMM drops into any standard DDR4 UDIMM socket keyed for unbuffered ECC memory; alignment notches prevent reversed insertion. Most problems arise when the platform firmware expects registered DIMMs or a different rank configuration, so verifying the motherboard qualified-vendor list before purchase avoids a module that posts but does not train.

Questions sur cet article

Does the 1.20V DDR4 2133 module run cool and quiet under continuous server workloads?

Yes, the 1.20V DDR4 standard voltage keeps power draw low, so heat output is minimal and the module adds no audible noise to a server running all day.

My motherboard needs 288-pin DDR4 ECC UDIMM slots — does this 1Rx8 stick fit that requirement?

The module is a 288-pin DDR4 ECC UDIMM with 1Rx8 organisation, matching boards that accept unbuffered ECC DIMMs at PC4-17000 speed.

Can I add this CL15 stick alongside older DDR4 2133 ECC UDIMMs already in my workstation?

It will operate at the common 2133 MHz speed and 1.20V voltage; the system will run all modules at the slowest timing present, so the older CL15 or higher sticks stay compatible.
