128GB DDR4 2933MHz ECC LRDIMM Server Module

This 128GB DDR4 2933MHz ECC LRDIMM module is built for server platforms that require registered load-reduced memory. It delivers 128GB capacity in a single 288-pin DIMM running at 1.2V with CL21 latency. The 2S4Rx4 8Rx4 3DS/TSV organisation targets high-density configurations in compatible enterprise systems.

Replaces Hynix HMABAGL7A4R4N-WR in supported servers

The module is an equivalent replacement for the Hynix HMABAGL7A4R4N-WR part number. The upgrade is worth it when your server chassis and motherboard qualify 128GB LRDIMM population rules and the memory controller supports DDR4 2933MHz PC4-23400 operation. Systems limited to lower densities or standard RDIMM slots will not accept this module.

Verify motherboard LRDIMM qualification

Confirm the platform supports 288-pin DDR4 ECC LRDIMM at 2933MHz and that the memory controller can address 8Rx4 3DS/TSV ranks. Check the vendor memory QVL for the exact HMABAGL7A4R4N-WR part number and validate maximum capacity per channel. Without confirmed compatibility the module will not post or will run at reduced speeds.

Questions about this item

Does the 288-pin DDR4 LRDIMM fit a standard DDR4 server DIMM slot?

Yes, the 288-pin DDR4 form factor matches standard DDR4 DIMM slots in compatible servers.

Is the LRDIMM seated fully when the side clips click?

Press the module straight down until both side clips snap closed; the load-reduced design needs even pressure to seat all 128GB of capacity.

How long does the ECC LRDIMM last under continuous server workloads?

The module is tested for dependable operation and backed by a lifetime warranty for the duration of use.
