Server DDR5 ECC UDIMM

This 16 GB DDR5 module adds error-correcting memory to compatible servers and workstations. It runs at 4800 MHz with CL40 latency and standard 1.1 V operation. The single-rank 1Rx8 layout uses major-brand chips on a 288-pin unbuffered DIMM. It is built for systems that require ECC UDIMM memory.

Build integration notes

The module fits DDR5 server platforms that accept ECC UDIMM modules and 1.1 V power. No heat spreader is present, so airflow in the chassis should be adequate. As a single 16 GB stick it leaves other DIMM slots free for matching modules to populate memory channels. Verify the motherboard manual for supported speeds and population rules before installation.

Upgrade context

This part replaces a missing or smaller ECC UDIMM in a DDR5 server or workstation. The jump is worthwhile when the workload demands error correction and the platform supports DDR5 4800 speeds. It is not suitable for desktop or laptop systems that lack DDR5 ECC UDIMM support.

Questions about this item

At what CAS latency does the CL40 timing limit sustained throughput?

The module runs at CL40, which is the primary latency figure governing access speed under continuous load.

How much heat and noise does the 1.1 V unbuffered DIMM generate during all-day operation?

Operating at 1.1 V with no heat spreader, it produces minimal heat and draws standard DDR5 power, while silent passive cooling handles continuous duty.

Which motherboard slot and memory controller are required for this 288-pin ECC UDIMM to function?

It needs a DDR5 server or workstation board with a 288-pin UDIMM slot and an ECC-capable memory controller; desktop and laptop platforms are not compatible.
