128GB DDR4 2666 ECC RDIMM Server Module

This 128GB DDR4 2666 ECC RDIMM module is built for servers and workstations that require registered memory with error correction. It operates at 1.20V with a CAS latency of CL19 and uses a 288-pin DIMM form factor. The module is a compatible replacement for Hynix HMABAGR7A4R4N-VN and features an 8Rx4 rank configuration using 3DS/TSV technology.

Registered DDR4 2666 limits and platform constraints

Registered DIMMs only function on platforms with a registered memory controller; consumer desktop chipsets will not recognise them. The DDR4 2666 standard caps the data rate at 2666 MT/s and the module voltage at 1.20V, so systems limited to lower speeds will downclock automatically. Mixed-rank populations may reduce the maximum supported speed on some server boards.

Verify DIMM slots, rank limits

Confirm that your motherboard accepts 288-pin DDR4 RDIMMs and supports 8Rx4 3DS/TSV modules at the intended capacity per slot. Check the qualified vendor list for the Hynix HMABAGR7A4R4N-VN part number or an equivalent 128GB registered specification. Ensure the system BIOS is current and that the power supply delivers stable 1.20V to the memory subsystem.

Questions sur cet article

Should I buy this single 128GB module or look for a kit of smaller sticks?

This is a single 128GB module (1x 128GB). Using one stick runs in single-channel mode; adding identical modules later enables multi-channel bandwidth if your platform supports it.

What does the 2666 MHz rating actually deliver inside a server?

The module runs at DDR4 2666 with CL19 latency at 1.20V. Real-world throughput depends on your CPU memory controller and the number of populated channels.

Will the 288-pin ECC RDIMM fit and run at the rated speed in my system?

It uses the standard DDR4 288-pin RDIMM form factor with ECC and registered buffering. Compatibility and maximum speed are determined by your motherboard and processor specifications.
