128GB DDR4 2933MHz ECC LRDIMM Server Memory

This 128GB DDR4 2933MHz PC4-23400 ECC Load Reduced DIMM targets server administrators who need maximum single-module capacity for memory-intensive workloads. The 288-pin module operates at 1.20V with CL21 latency and uses 2S4Rx4 3DS/TSV organisation. It replaces Micron MTA144ASQ16G72LSZ-2S9 series parts in compatible platforms.

Load Reduced DIMM electrical limits

Load Reduced DIMMs reduce electrical load on the memory bus to allow higher densities per channel, but the platform chipset and BIOS must explicitly support LRDIMM operation. Mixing LRDIMM with standard RDIMM or unbuffered DIMM types on the same channel is not supported. Maximum usable capacity and population rules are defined by the server vendor and cannot be exceeded by module specification alone.

Pre-purchase compatibility checks

Confirm that your server model qualifies for 128GB DDR4 LRDIMM modules at 2933MHz and that the specific Micron part numbers listed are approved replacements. Verify the maximum supported memory per socket, allowed rank configurations per channel, and whether BIOS updates are required for 3DS/TSV devices. Ensure the system does not restrict LRDIMM use to specific slots or processor generations.

Preguntas sobre este artículo

Should I choose the single 128GB module or look for a 16GB alternative for my server?

This product is sold as one 128GB module; if your system supports 128GB LRDIMMs per slot it delivers maximum capacity per DIMM, while 16GB modules would require eight slots to reach the same total.

What does the 2933MHz rating mean once the module is installed in a real machine?

The module runs at DDR4 2933 MT/s with CL21 latency at 1.20V, so the memory controller transfers data at that rate while ECC corrects single-bit errors and load-reduced buffering reduces electrical load on the bus.

How does the DDR4 LRDIMM interface cap performance in practice?

The 288-pin DDR4 LRDIMM form factor operates at 1.20V with 2S4Rx4 3DS/TSV organisation; the memory controller negotiates speed and rank count, so actual throughput is limited by the platform's maximum supported DDR4 frequency and rank-per-channel limits.
