128GB DDR4 ECC LRDIMM for Servers

This 128GB DDR4 2666MHz ECC Load Reduced DIMM targets administrators expanding memory capacity in compatible Supermicro platforms. The octal-rank module uses Micron 3DS/TSV technology to deliver high density within a single 288-pin slot.

Supermicro Certified Build and 288-Pin LRDIMM Format

A-Tech validates each unit against Supermicro MEM-DR412LF-LR26 specifications using Micron MTA144ASQ16G72LSZ-2S6E1 components. The Load Reduced architecture reduces electrical load on the memory bus, while the standard 1.20V operation and CL19 latency align with DDR4 21300 server requirements.

Verify Platform Support for 128GB Octal-Rank Modules

Confirm your motherboard and CPU support 128GB LRDIMMs with 2S4Rx4 (8Rx4) organisation and 3DS/TSV stacking before ordering. Systems limited to lower ranks, standard RDIMMs, or smaller maximum capacities will not recognise this module. Buyers needing non-ECC memory or lower-density DIMMs should select a different product.

Questions sur cet article

What does DDR4 2666 PC4-21300 mean for real-world bandwidth?

DDR4 2666 PC4-21300 indicates the module runs at 2666 MT/s with a PC4-21300 designation; peak throughput is determined by the platform's memory controller and channel configuration.

What physical clearance does a 288-pin LRDIMM need?

A 288-pin LRDIMM fits standard DDR4 DIMM slots; verify motherboard DIMM spacing and heatsink clearance because load-reduced modules are taller than standard UDIMMs.

How is this 128GB octal-rank module installed correctly?

Align the 288-pin key notch with the slot, press firmly until both retention clips lock; the common mistake is seating only one side, which prevents ECC initialisation.
