128GB DDR4 2400 ECC LRDIMM Server Module

This 128GB DDR4 2400 module is built for servers and workstations that require high-density memory with error correction. It uses a load-reduced DIMM design to lessen electrical load on the memory controller. The module operates at 1.2V standard voltage with CL17 latency. It targets IT professionals upgrading compatible enterprise platforms.

288-Pin LRDIMM Form Factor and Compatibility

The module fits a standard 288-pin DDR4 DIMM slot and presents an 8Rx4 rank structure via 3DS/TSV stacking. Load-reduced buffering allows larger memory populations per channel than standard registered DIMMs. Buyers must verify their system qualification list for HMABAGL7M4R4N-UL equivalence before installation. Systems not validated for LRDIMM or this rank configuration will not support it.

128GB Capacity at DDR4 2400 Speed

A single module delivers 128GB at PC4-19200 data rates, providing substantial headroom for virtualization, in-memory databases and large dataset processing. The 2400 MT/s rate and CL17 timing set the bandwidth ceiling for memory-intensive workloads. Applications demanding higher throughput or lower latency than DDR4 2400 provides will not benefit from this module.

Questions about this item

Does the 128GB LRDIMM module run at CL17 latency under sustained server workloads?

Yes, the module is specified at CAS latency CL17 for DDR4 2400 operation.

How much heat and power does the 1.2V LRDIMM generate when running continuously in a 24/7 environment?

The module operates at standard DDR4 1.2V voltage; LRDIMM buffering reduces electrical load on the memory bus, helping manage heat during sustained use.

Will this 288-pin DDR4 LRDIMM work in my existing 262-pin server slots?

No, this module uses the 288-pin DDR4 DIMM form factor and requires matching 288-pin registered/LRDIMM slots.
