High-density server module

This A-Tech module delivers 128GB of DDR4 ECC LRDIMM memory for servers that need large single-stick capacity. It targets administrators upgrading compatible Dell platforms where registered load-reduced DIMMs are required.

Capacity and headroom

The 128GB stick runs at 3200MHz with CL22 latency and 1.2V operation, providing substantial headroom for virtualisation, in-memory databases and heavy multitasking. Workloads that exceed this single-module limit will require additional populated slots.

Build integration

The 288-pin DDR4 form factor fits standard server DIMM slots that support LRDIMM signalling and ECC. No heat spreader is fitted, so airflow across the module must be maintained by the chassis. Compatibility should be verified against the system’s qualified vendor list before installation.

Questions about this item

Will this 128GB DDR4 3200MHz ECC LRDIMM work alongside my existing DDR4 RDIMMs in the same server?

Mixing Load Reduced DIMMs with standard Registered DIMMs is not supported; the memory controller requires all installed modules to be the same type, so this 4DRx4/4Rx4 LRDIMM must populate slots by itself or with identical LRDIMMs.

How can I confirm the 128GB DDR4 3200MHz ECC LRDIMM is running at its rated 3200 MT/s and CL22 after installation?

Enter the server BIOS or UEFI and open the memory information screen; it should report 3200 MT/s (PC4-25600), 1.20 V, ECC enabled and CAS latency 22 for the installed module.

What is included in the box with the 128GB DDR4 3200MHz ECC LRDIMM and do I need to buy anything else to install it?

The package contains one 128GB 288-pin DDR4 ECC LRDIMM module; no heat spreader, cables, tools or additional components are included or required for installation in a compatible server slot.
