128GB DDR4 ECC RDIMM kit

This A-Tech kit provides 128GB of DDR4 server memory across eight 16GB registered DIMMs. Each module runs at 2133 MHz with CL15 latency at the standard 1.2V. Error-correcting code and registered buffering protect data integrity in multi-socket platforms. The 2Rx8 dual-rank organisation increases density per channel for memory-heavy workloads.

For DDR4 servers needing registered ECC

Suitable for administrators expanding capacity in compatible DDR4 server or workstation boards that require registered ECC DIMMs. The eight-module kit fills multiple channels for balanced bandwidth. Not suited for desktop or laptop systems that accept only unbuffered non-ECC memory. Buyers who need higher frequencies or lower latencies should verify platform support before ordering.

Fits 288-pin DDR4 RDIMM slots

Installs in standard 288-pin DDR4 DIMM sockets on server and workstation motherboards that specify registered ECC support. The 1.2V operation matches the DDR4 baseline, leaving headroom for other components on the 12V rail. Populating all eight slots maximises channel interleaving for throughput-sensitive applications such as virtualisation hosts and database nodes.

Questions about this item

Does my motherboard need 288-pin DDR4 RDIMM slots to use this 128GB kit?

Yes, this kit requires a server or workstation motherboard with 288-pin DDR4 RDIMM slots that support ECC Registered memory at 2133 MHz.

Can I mix these 2Rx8 1.20V modules with existing 1Rx4 DDR4 2133 ECC RDIMMs?

Mixing dual-rank 2Rx8 modules with single-rank 1Rx4 modules is possible if the motherboard supports mixed rank populations, but you must follow the manual's channel and slot rules.

How can I confirm the 8x16GB kit is running at CL15 2133 MHz after installation?

Check the BIOS memory information or use a tool like CPU-Z to verify each module shows 2133 MHz, CL15 timings, 1.20V, and ECC Registered status.
