16GB DDR4 3200MHz ECC RDIMM

This 16GB DDR4 3200MHz ECC RDIMM module uses Micron chips and runs at PC4-25600 speed with CL22 latency. It is a 2Rx8 dual-rank registered DIMM operating at 1.20V. The module carries Supermicro certification for verified compatibility with qualified Supermicro platforms.

Suited for servers needing registered ECC memory

This module fits systems that require registered ECC DDR4 memory in a 288-pin RDIMM form factor. It is not suitable for desktop or laptop platforms that accept only unbuffered non-ECC UDIMMs. Buyers whose motherboards lack registered DIMM support should look at a different memory type.

Handles registered ECC workloads within a single

The 16GB capacity provides headroom for virtualization, database, or compute tasks that benefit from ECC protection and registered signalling. A single module leaves additional slots open for further expansion. Systems needing more than 16GB per channel or higher memory density will require additional or larger modules.

Questions about this item

My motherboard only has 288-pin DDR4 slots — will this RDIMM fit and run at 3200 MHz?

Yes, the module uses the standard 288-pin DDR4 RDIMM form factor and is rated for 3200 MHz (PC4-25600) at 1.2 V, so it will install and operate at that speed in any compatible 288-pin DDR4 slot.

I already have single-rank DDR4 ECC RDIMMs installed; can I mix them with this 2Rx8 dual-rank module?

Mixing ranks is often supported, but the memory controller will run all populated channels at the lowest common speed and may require specific slot population rules — check your system or motherboard manual for approved rank-mixing configurations.

After installation, how can I confirm the module is running at 3200 MHz with ECC active?

Enter the BIOS/UEFI or use a tool such as dmidecode, CPU-Z or IPMI to verify the reported speed shows 3200 MHz (PC4-25600) and that ECC status reads "Enabled" or "Corrected Errors" counters are present.
