Hynix HMA42GR7AFR4N-UH 16GB DDR4-2400 ECC REG DIMM Server Memory

Server ECC REG DIMM

This Hynix module is a 16 GB DDR4-2400 ECC registered DIMM built for server and workstation platforms that require error-correcting memory. It is intended for administrators and integrators populating multi-socket systems where data integrity and signal stability across many modules are essential.

Platform compatibility check

Verify that your motherboard supports DDR4 registered ECC memory and that the CPU memory controller accepts 2400 MT/s registered modules. Confirm the number of available DIMM slots and the maximum capacity per channel before ordering. This module will not function in desktop or laptop boards that only accept unbuffered non-ECC memory.

Sustained operation behaviour

Registered buffering reduces electrical load on the memory bus, allowing stable operation when all slots are populated under continuous workloads. ECC circuitry detects and corrects single-bit errors during long compute runs, preventing silent data corruption. The module maintains rated 2400 MT/s throughput without downclocking in typical server thermal environments.
