Server memory module

This Hynix HMAG78EXNRA module provides 16 GB of DDR4 ECC registered memory rated at 3200 MT/s. It is built for enterprise servers and workstations that require error correction and registered signalling for stable operation under continuous load.

Not for consumer desktops or laptops

The registered ECC design is incompatible with standard consumer motherboards that accept only unbuffered non-ECC memory. Buyers who need memory for a home PC, gaming rig or typical laptop should look at unbuffered DDR4 modules instead.

DDR4-3200 ECC registered specification

The DDR4-3200 ECC registered specification is the single attribute that decides whether this module fits the target platform. Only systems designed for registered ECC DDR4 at this data rate can use the part.

Questions about this item

How much power does the 16GB DDR4-3200 ECC REG DIMM draw when running continuously?

The module operates at the standard DDR4 voltage of 1.2 V, keeping power draw low during all-day server workloads.

What motherboard feature must my system already support for this HMAG78EXNRA module to function?

Your board must accept registered ECC DDR4 DIMMs and have a compatible 288-pin slot with the correct memory controller.

Will this registered ECC DIMM work alongside older unbuffered DDR4 sticks I want to keep installed?

No — registered and unbuffered modules cannot be mixed on the same channel, so the older sticks would need to be removed.
