Capacity and rank

This module delivers 32 GB of DDR4 memory in a dual-rank 2Rx4 layout. The density suits virtualisation hosts and database nodes that need large addressable space per DIMM slot. Workloads that exceed the per-module capacity will require additional populated slots.

Speed and voltage

Rated at DDR4 2400 (PC4 19200), the stick runs at 1.20 V standard voltage. Throughput is adequate for mainstream server tasks but becomes a bottleneck in memory-bound HPC or high-frequency trading workloads. Latency scales with the rated frequency and cannot be improved without platform overclocking support.

Registered ECC integration

The registered buffer and on-die ECC reduce electrical load on the memory controller and correct single-bit errors. A compatible server board with registered DIMM support is mandatory; unbuffered consumer platforms will not accept this module. The 288-pin form factor fits standard DDR4 DIMM slots in qualified Supermicro and other vendor systems.

Questions about this item

Will this 288-pin DDR4 2400 ECC registered DIMM run with older DDR4 modules I already have?

The module operates at DDR4 2400 speed; mixing speeds is handled by the platform and may run all modules at the lowest common rate.

How can I confirm the 32 GB 2Rx4 registered ECC module is detected correctly after installation?

Check the server BIOS or OS memory report for 32 GB total, ECC enabled, registered mode active and the correct 2400 MT/s data rate.

Does the box contain only the HMA84GR7AFR4N-UH 32 GB DDR4 2400 ECC REG DIMM or are extra parts included?

The package includes the single 288-pin DIMM; no cables, brackets or additional components are supplied.
