128GB DDR4 3200 ECC LRDIMM kit

This A-Tech kit provides 128GB of server memory as two 64GB modules. It runs at DDR4 3200 with a CAS latency of CL22 and operates at 1.2V. The modules use Load Reduced DIMM technology with 4Rx4 quad-rank organisation for high-density server and workstation platforms.

For DDR4 servers needing maximum registered capacity

This memory suits administrators upgrading compatible DDR4 servers or workstations that require ECC Load Reduced modules. It is not for desktop or laptop computers, which cannot use LRDIMM registered memory. Systems limited to standard RDIMM or UDIMM form factors, or those requiring lower-rank configurations, should look elsewhere.

Quad-rank 4Rx4 organisation per module

Each 64GB module presents a 4Rx4 quad-rank x4 layout that determines compatibility with the memory controller. The server or workstation motherboard must explicitly support 4Rx4 LRDIMM population rules and the resulting electrical load. Verify the platform's qualified vendor list before purchase.

Questions about this item

How much power does each 64 GB 3200 MHz CL22 LRDIMM draw at the rated 1.2 V?

Each module operates at the standard DDR4 voltage of 1.2 V; exact wattage depends on the server platform and workload.

What server platform features are required for these 288-pin quad-rank LRDIMMs to function?

The system must support DDR4 ECC Load Reduced DIMMs with 4Rx4 organisation and accept 64 GB per slot.

Will the 4Rx4 LRDIMM organisation change memory-channel population rules on my existing DDR4 server?

Quad-rank LRDIMMs reduce electrical load on the bus, but population limits are set by the server vendor — consult the system manual.
