128GB DDR4 2933MHz ECC LRDIMM Server Module

This 128GB DDR4 2933MHz ECC LRDIMM module targets server administrators who need high-capacity registered memory for compatible enterprise platforms. The load-reduced design helps reduce electrical load on the memory bus when populating multiple slots. It operates at the standard DDR4 voltage of 1.20V with CL21 latency. Buyers who need non-ECC UDIMMs or lower-density registered DIMMs should look elsewhere.

Verify DDR4 LRDIMM Support and Rank Compatibility

Confirm that your server motherboard and processor support DDR4 2933MHz LRDIMM modules with a 4DRx4 rank configuration before ordering. Check the system documentation for maximum supported capacity per slot and total memory population rules. The 288-pin form factor fits standard DDR4 DIMM sockets, but electrical compatibility depends on the platform memory controller. Systems limited to RDIMM or UDIMM types cannot use this module.

Single-Module Upgrade for High-Density Server Builds

This single 128GB module plugs directly into an available 288-pin DDR4 DIMM slot on a supported server board. No heat spreader is included, so airflow across the module relies on system cooling. The load-reduced architecture frees electrical headroom for additional DIMMs in multi-slot configurations. ECC functionality provides error detection and correction for data integrity in mission-critical workloads.

商品問答

Does the 128GB DDR4 2933MHz ECC LRDIMM ship as a single 288-pin module or do I need to buy additional sticks?

The product is a single 128GB module in a 288-pin DDR4 LRDIMM form factor. No extra sticks are included; add more modules only if your server has free slots and supports the total capacity.

How do I choose between the Micron MTA72ASS16G72LZ-2G9 and MTA72ASS16G72LZ-2G9B3 part numbers listed?

Both part numbers refer to the same 128GB DDR4 2933MHz ECC LRDIMM specification. This A-Tech module is an equivalent replacement for either Micron part number, so you can use it regardless of which one your system requires.

What does the PC4-23400 rating mean for real-world server performance with this CL21 1.20V module?

PC4-23400 indicates a peak transfer rate of 23400 MB/s at 2933 MT/s. The CL21 latency and 1.20V operation are standard for DDR4 LRDIMMs, delivering high bandwidth for memory-intensive server workloads while maintaining signal integrity through load reduction.
