Server DDR5 RDIMM for registered ECC platforms

This 16 GB DDR5-5600 module uses a 288-pin RDIMM form factor with registered signal processing and on-die ECC. It is built for servers and workstations that require registered memory with error correction. The single-rank 1Rx8 organisation and CL46 timing suit platforms qualified for PC5-44800 speeds. Systems needing unbuffered UDIMMs or non-ECC memory cannot use this part.

Thermals and power in normal operation

The module runs at a typical VDD and VDDQ of 1.10 V with VPP at 1.8 V and VDDSPD between 1.8 V and 2.0 V. No heat spreader is fitted, so airflow across the 31.25 mm PCB height handles cooling. Registered buffering reduces electrical load on the memory bus, helping keep power draw steady under sustained server workloads.

Registered ECC with on-die correction

The decisive specification is the combination of registered buffering and on-die ECC with x80 organisation across two independent I/O sub-channels. This provides error detection and correction inside the DRAM before data reaches the bus. Buyers whose platforms require unbuffered memory or lack registered DIMM support must choose a different module type.

Questions about this item

How do I install this 288-pin DDR5 RDIMM and what step is often missed?

Align the notch with the motherboard slot key, press firmly until both retention clips click, then verify the module sits flush; the step often missed is confirming the BIOS detects the correct 5600 MHz speed and CL46 timing after first boot.

What maintenance or replacement will this 16 GB registered ECC module need over time?

No routine maintenance is required; the module has no heat spreader so keep server airflow clean, and replace only if ECC correctable error counts rise or the system reports a hard memory failure.

What limit appears first when this DDR5-5600 CL46 RDIMM runs sustained workloads?

The CL46 latency at 1.10 V becomes the bottleneck before bandwidth, as the single-rank 1Rx8 organisation and 46-45-45 timings cap throughput under continuous heavy load.
