Capacity and form factor

This A-Tech module provides 16GB of DDR5 memory in a 288-pin UDIMM form factor. It operates at 4800MHz with a CAS latency of 40 and runs at the standard 1.10V. The kit is an unbuffered, single-rank 1Rx8 design with on-die ECC for data integrity.

Who this suits

Builders upgrading or repairing servers and workstations that specifically require DDR5 4800 unbuffered ECC UDIMMs will find this module a direct fit. It is not for systems that need registered or load-reduced DIMMs, nor for boards that only accept non-ECC memory.

Deciding specification

The critical match is the 1Rx8 rank and chip organisation combined with unbuffered ECC operation at 1.10V. Verify that your platform supports this exact configuration before ordering, as registered or differently ranked modules will not function correctly.

Questions sur cet article

How does the 1Rx8 rank configuration affect sustained throughput on this DDR5 4800 module?

The single-rank 1Rx8 layout keeps all 16 GB on one rank, allowing the memory controller to access the full capacity without rank-to-rank switching delays during long workloads.

What thermal and acoustic impact should I expect when this unbuffered ECC UDIMM runs continuously at 1.10 V?

With no heat spreader and standard 1.10 V DDR5 voltage, the module relies on case airflow; it adds minimal heat and produces no audible noise of its own.

Which motherboard slot and firmware features are required for this 288-pin DDR5 ECC UDIMM to operate?

You need a DDR5-compatible motherboard with a 288-pin UDIMM slot and BIOS support for ECC on unbuffered memory.
