16GB DDR4 3200 ECC Registered RDIMM

This 16GB DDR4 3200 ECC Registered RDIMM is built for workstations and servers that require error-correcting registered memory. It operates at CL22 latency with a 1.2V voltage and a 2Rx8 rank configuration. The module is a direct replacement for QNAP part number RAM-16GDR4ECT0-RD-3200.

Upgrading from unbuffered or non-ECC memory

This registered ECC module cannot be mixed with unbuffered memory and will not function in standard desktop computers. The upgrade is worth it when your server or workstation motherboard specifically requires registered ECC DIMMs to maintain data integrity and system stability.

Verify registered ECC support and slot count

Before ordering, confirm that your system supports 288-pin DDR4 registered ECC memory and that you are not mixing it with unbuffered modules. Check the number of available DIMM slots and the maximum supported capacity per slot to ensure compatibility.

Perguntas sobre este artigo

Will the 288-pin DDR4 RDIMM fit my server's memory slots?

Yes — the module uses the standard 288-pin DDR4 RDIMM form factor, so it fits any server or workstation slot designed for registered DDR4 memory.

What is the correct way to seat the 2Rx8 registered module, and what step do people often miss?

Align the notch with the slot key, press straight down until both side clips click, then verify the system recognises the full 16 GB at 3200 MT/s — skipping the clip check is the common mistake.

When should I expect to replace this ECC registered DIMM?

The module has no moving parts and runs at 1.2 V; replacement is only needed if a memory test reports uncorrectable errors or the server's workload outgrows 16 GB capacity.
