Server-grade DDR4 ECC RDIMM

This 8 GB registered module is built for server and workstation platforms that require error-correcting memory. It operates at the standard DDR4 voltage of 1.20 V and uses a 288-pin DIMM form factor. The unit is a direct replacement for Hynix HMA41GR7AFR8N-UH and HMA41GR7BJR8N-UH part numbers.

Registered 2Rx8 organisation at CL17

The single decisive specification is the 2Rx8 registered layout combined with CL17 latency at 2400 MHz (PC4-19200). Systems that expect unbuffered UDIMMs or a different rank configuration will not accept this module, so verifying the motherboard’s qualified vendor list is essential before purchase.

Steady throughput under continuous workloads

Registered buffering reduces electrical load on the memory controller, allowing sustained data rates during prolonged compute tasks without the timing drift seen on unbuffered sticks. ECC correction maintains data integrity across extended runs, making the module suitable for virtualisation hosts, database servers and other 24/7 environments.

Questions sur cet article

What does the 2400 MHz speed actually deliver in a server?

The module runs at 2400 MT/s with CL17 latency and 1.20 V, giving the rated PC4-19200 data rate when the platform enables that speed.

How does the registered ECC interface affect usable bandwidth?

The RDIMM places a register between the DRAM and the memory controller, adding one cycle of latency but allowing larger capacities per channel while ECC corrects single-bit errors.

What physical slot and clearance does this 288-pin DIMM need?

It fits a standard DDR4 288-pin RDIMM slot; the module height follows the JEDEC profile so it clears typical server heatsinks.
