Hynix HMA84GR7AFR4N-UH 32GB DDR4-2400 ECC REG DIMM accessory

SKU CH-890M-JKZDJ

32 GB DDR4-2400 ECC registered DIMM for compatible servers and workstations

  • 32 GB capacity supports memory-intensive workloads
  • DDR4-2400 speed delivers reliable data throughput
  • ECC registered design detects and corrects memory errors
  • 288-pin DIMM form factor fits compatible server boards
  • Hynix manufacturing ensures consistent component quality

Server-grade memory module

This is a 32GB DDR4-2400 ECC registered DIMM built for server and workstation platforms that require error-correcting memory. It is not compatible with standard consumer desktop or laptop motherboards that lack registered DIMM support. Buyers needing non-ECC or unbuffered memory for a home PC cannot use this module.

Installation requirements

The module installs only in DDR4 slots wired for registered ECC memory; the system BIOS must support registered modules or the system will not post. A common mistake is attempting to use this DIMM in a consumer board that accepts only unbuffered memory. No special tools are required beyond normal DIMM seating.

DDR4-2400 practical limits

The DDR4-2400 interface caps peak bandwidth at the rated data rate, so sustained throughput cannot exceed that specification. Registered buffering adds a small latency overhead compared with unbuffered modules. Systems that cannot run memory at 2400 MT/s will downclock the module to the highest supported speed.
