4GB DDR4 2133 ECC RDIMM for servers

This 4GB DDR4 2133 ECC registered DIMM is built for server and workstation platforms that require error-correcting memory. The module uses major-brand chips and runs at the standard 1.2V DDR4 voltage. It suits administrators upgrading or repairing compatible systems with a single 4GB stick.

Check DDR4 RDIMM support and slot count

Verify that your motherboard accepts DDR4 registered ECC DIMMs and has a free 288-pin slot before ordering. The module operates at CL15 latency and PC4-17000 speed, so the platform must support this data rate. Confirm the maximum capacity per slot and total system limit in your hardware documentation.

Replaces specific Hynix part numbers

The module is a compatible equivalent for Hynix HMA451R7AFR8N-TF, HMA451R7AFR8N-TFT1 and HMA451R7MFR8N-TF, simplifying sourcing for those exact part numbers. No extra accessories or software are bundled with the memory stick.

Questions sur cet article

What is included with the A-Tech 4GB DDR4 2133 ECC RDIMM module and is anything else required for installation?

The package contains one 4GB DDR4 2133MHz PC4-17000 ECC Registered DIMM with 288 pins and CL15 latency. No additional components are needed; the module installs directly into a compatible server or workstation memory slot.

Should I choose this 4GB 1Rx8 CL15 module or a different capacity or rank for my server?

Select this 4GB 1Rx8 CL15 module when your system requires a single-rank registered ECC DIMM at 2133MHz. If your platform supports higher densities per slot or needs multiple ranks per channel for maximum bandwidth, a larger capacity or dual-rank module would be appropriate instead.

What does the 2133MHz PC4-17000 rating mean for real-world server performance?

The 2133MHz PC4-17000 rating indicates a maximum data transfer rate of 17 GB/s per module at CL15 latency and 1.2V. In a real machine, actual throughput depends on the memory controller, channel population, and workload, but the module will operate at its rated speed when the platform supports DDR4-2133.
