NEMIX RAM
32 GB DDR4 3200 ECC registered RDIMM 2Rx4 HMA84GR7CJR4N-XN compatible with 1.2 V operation and CL22 latency
This NEMIX RAM module is a 32GB DDR4 3200 ECC registered DIMM designed for servers and workstations that require error-correcting memory. It operates at 1.2V with CL22 latency and uses a 2Rx4 organisation across 288 pins. The stick is validated for compatibility with Hynix server platforms.
The jump is worth it when your current registered DIMMs limit total system memory or run at a slower data rate than PC4-25600. Adding this 32GB module increases density per slot so you can reach higher aggregate capacities without populating every available socket. It also standardises on a single speed grade across the chassis.
This module suits administrators who need a tested, registered ECC DIMM backed by stress-tested validation for Hynix-based systems. Builders using consumer motherboards that accept only unbuffered non-ECC memory should look elsewhere, as those platforms cannot use registered modules. Environments requiring registered DIMMs with different rank configurations or voltage levels should also evaluate other options.

Yes, the module uses the standard 288-pin DDR4 RDIMM form factor with registered buffering and ECC, matching server motherboards that accept registered DIMMs.
Align the notch with the slot key, press firmly until both retention clips click, then verify in BIOS that the registered ECC DIMM reports 32 GB at 3200 MT/s.
No firmware updates are required for the memory itself; the module retains its 1.20 V CL22 timings and ECC function without a battery, though the server's own BIOS may receive vendor updates.
