Supermicro Certified 128GB LRDIMM

This Supermicro certified 128GB DDR4 2666MHz LRDIMM module targets servers and workstations that require maximum memory capacity per slot. The octal-rank design uses Micron 3DS TSV chips to reach 128GB in a single 288-pin package. ECC load-reduced operation helps maintain data integrity in dense configurations.

Sustained load behaviour

Load-reduced buffering reduces electrical load on the memory controller, allowing the module to sustain 2666MHz throughput under continuous multi-threaded workloads. The 1.20V operating voltage and CL19 latency support stable operation during extended compute or virtualisation tasks without thermal throttling.

Compatibility checks

Verify that your motherboard supports DDR4 LRDIMM modules and the 2S4Rx4 octal-rank organisation before ordering. Confirm the maximum supported capacity per slot and total system capacity in the vendor documentation. Ensure the BIOS revision lists this module or the Micron MTA144ASQ16G72LSZ-2S6E1 part number as qualified.

Perguntas sobre este artigo

How much power does the 128GB DDR4 2666MHz LRDIMM draw at its 1.20V operating voltage?

The module runs at the standard DDR4 voltage of 1.20V. As a Load Reduced DIMM, it reduces electrical load on the memory bus, which helps manage power draw in dense configurations. Actual wattage depends on your specific server workload and configuration.

What motherboard slot and CPU memory controller features are required to run this 288-pin 8Rx4 LRDIMM?

You need a server motherboard with DDR4 288-pin DIMM slots and a CPU memory controller that supports Load Reduced DIMMs and octal-rank (8Rx4) modules. The platform must also support ECC and the PC4-21300 speed grade for full operation.

Can this Supermicro-certified 128GB LRDIMM be mixed with older RDIMMs in the same server?

Mixing Load Reduced DIMMs with standard Registered DIMMs is not supported on any platform. All populated slots must use the same memory technology. Check your system manual for supported population rules with 8Rx4 LRDIMMs.
