128GB DDR4 LRDIMM for Server Workloads

This 128GB DDR4 3200MHz ECC Load Reduced DIMM targets servers that require high-density registered memory. It replaces Hynix HMABAGL7CBR4N-XN and HMABAGL7ABR4N-XN modules in compatible platforms. The single 288-pin module delivers 128GB capacity for memory-intensive applications.

128GB Capacity with CL22 at 1.20V

The module runs at DDR4 3200 (PC4-25600) with a CAS latency of 22 and standard 1.20V voltage. Its 4DRx4/4Rx4 rank configuration provides the density needed for virtualisation and large datasets. Systems not qualified for 128GB LRDIMMs or requiring lower-rank modules cannot use this memory.

288-Pin LRDIMM Fit and Compatibility

This Load Reduced DIMM fits 288-pin DDR4 server slots that specifically support LRDIMM topology and 128GB per slot. It frees additional slots for further expansion where the platform allows. Verify your system’s qualified vendor list before purchase as standard RDIMM or UDIMM slots will not accept this module.

Questions about this item

Will this 128GB DDR4 3200MHz ECC LRDIMM run at its rated speed alongside my existing DDR4 modules?

The module operates at DDR4 3200 (PC4-25600) with CL22 latency at 1.20V; the system will negotiate the highest common speed supported by all installed memory and the memory controller.

How can I confirm the 128GB ECC LRDIMM is detected and error-correction is active after installation?

Check the system BIOS or UEFI memory information screen for 128GB total capacity, DDR4 3200 speed, and ECC status reported as enabled or active.

Does the single 128GB 288-pin LRDIMM ship with any heatsink, cable or installation tool?

The module has no heat spreader and includes only the memory stick itself; no heatsink, cable or tool is supplied.
