128GB DDR4 ECC LRDIMM kit

This A-Tech kit delivers 128GB of DDR4 2133 server memory in a dual-channel pair of 64GB modules. It is built for servers and workstations that require ECC load-reduced DIMMs and will not function in desktop or laptop platforms.

Capacity and headroom

Two quad-rank 4Rx4 modules provide dense capacity for virtualization, large databases and memory-heavy workloads. The 2133 MHz speed and CL15 latency set the throughput ceiling, so applications demanding higher bandwidth will exhaust headroom before capacity becomes the limit.

DDR4 288-pin interface limits

The 288-pin DDR4 LRDIMM form factor fits only platforms qualified for DDR4 ECC load-reduced memory at 1.2V. Systems that accept only standard registered DIMMs, unbuffered DIMMs or a different DDR generation cannot use these modules.

Questions about this item

Will the 288-pin DDR4 LRDIMMs fit and operate alongside existing DDR4 RDIMMs in the same server?

No, Load Reduced DIMMs and standard Registered DIMMs use different electrical signalling and cannot be mixed in the same system; all slots must use identical LRDIMM modules.

How can I verify the kit is running at 2133 MHz with ECC active after installation?

Check the BIOS memory information or use a tool such as dmidecode to confirm each 64 GB module reports 2133 MT/s, CL15, 1.20 V and ECC Load Reduced status.

What is included in the box and is any extra hardware required?

The box contains two 64 GB DDR4 2133 MHz ECC LRDIMM modules (288-pin, 4Rx4, 1.20 V); no additional cables, brackets or software are needed for installation.
