4GB DDR4 2133MHz ECC UDIMM

This 4GB DDR4 2133MHz ECC UDIMM module is built for servers and workstations that require error-correcting memory in an unbuffered design. It suits administrators upgrading compatible Micron platforms where registered DIMMs are not needed. The single-rank 1Rx8 organisation keeps electrical loading low on the memory bus. Buyers needing registered or load-reduced modules cannot use this part.

4GB capacity with CL15 latency

The module provides 4GB of capacity at PC4-17000 speed with a CAS latency of 15 cycles. It handles typical file-serving, virtualization host, and database workloads that fit within this footprint. Larger datasets or heavy multi-VM consolidation will exceed the available headroom and require higher-density DIMMs. The 1.20V operating voltage matches standard DDR4 power envelopes.

288-pin DDR4 DIMM for compatible boards

The 288-pin DDR4 DIMM form factor fits standard unbuffered ECC slots on supported server and workstation motherboards. No additional cooling or specialised power delivery beyond the slot specification is required. The Micron chipset base ensures behavioural parity with the original MTA9ASF51272AZ-2G1A1 and MTA9ASF51272AZ-2G1B1 parts. Systems limited to registered memory or proprietary form factors will not accept this module.

Questions about this item

Will the 288-pin DDR4 ECC UDIMM work in a system that currently uses 262-pin DDR4 SO-DIMM modules?

No, the 288-pin DIMM form factor is physically incompatible with 262-pin SO-DIMM slots used in laptops and some compact servers.

How can I verify the module is running at 2133MHz with CL15 latency after installation?

Check the memory speed and timings in your system BIOS or use a utility like CPU-Z to confirm DDR4-2133 operation at 1.20V with ECC active.

Does the single 4GB 1Rx8 module ship alone, or are additional components like heat spreaders included?

The box contains only the 4GB DDR4 2133MHz ECC UDIMM module; no heat spreaders, cables, or installation tools are supplied.
