16GB DDR4 3200 ECC RDIMM for servers

This 16GB DDR4 3200 ECC RDIMM module is built for server and workstation systems that require registered memory with error correction. The 2Rx8 organisation and CL22 latency at 1.20V match the Hynix HMAG78EXNRA specification. It is a direct replacement part for that model.

Upgrade from non-ECC or slower DDR4

The module replaces non-ECC UDIMMs or slower DDR4 RDIMMs in platforms that support registered ECC memory. The jump is worth it when your workload demands data integrity and the motherboard accepts 288-pin RDIMMs at 3200 MT/s. Systems limited to UDIMM slots or lower speeds cannot use this module.

Check motherboard RDIMM support and slot count

Verify that your motherboard or server chassis lists DDR4 3200 RDIMM support and has an available 288-pin DIMM slot. Confirm the maximum capacity per slot and the total number of slots populated, as some platforms restrict rank count or total memory. The 262-pin form factor noted in the supplier data refers to SO-DIMM; this product is a 288-pin RDIMM.

Perguntas sobre este artigo

Will this 288-pin DDR4 3200 ECC RDIMM fit my server's DIMM slots?

The module uses the standard 288-pin DDR4 DIMM form factor and requires a slot that accepts registered ECC memory at 1.2 V.

What is the correct way to seat this 16 GB 2Rx8 RDIMM and what step is often missed?

Align the notch with the key, press firmly until both retention clips click, and verify the system recognises the full 16 GB at 3200 MHz.

How can I tell when this ECC RDIMM should be replaced?

Replace the module if the system logs corrected ECC errors that increase over time, or if memory diagnostics report uncorrectable failures.
