128GB DDR5 ECC UDIMM kit

This NEMIX RAM kit supplies 128GB of DDR5 memory across four 32GB modules. It runs at 5600MT/s with CL46 latency at 1.10V and includes on-die ECC. The unbuffered 288-pin UDIMMs use 2Rx8 organisation and are validated for the ASUS ROG Strix B650-A Gaming WiFi motherboard.

Workstations and servers needing data integrity

The ECC capability suits workloads where silent data corruption is unacceptable, such as ZFS storage nodes, virtualization hosts or scientific computing. Builds that require registered DIMMs, higher frequencies, lower latencies or RGB lighting should look at alternative memory lines.

Four ranks per module provide density headroom

The 2Rx8 layout lets the memory controller interleave across ranks, sustaining throughput on multi-threaded tasks. Capacity tops out at 128GB with this kit; larger configurations would need higher-density modules or additional DIMM slots.

Questions about this item

Does this DDR5 5600 ECC UDIMM kit require an ASUS ROG STRIX B650-A Gaming WiFi motherboard to function?

The kit is validated for the ASUS ROG STRIX B650-A Gaming WiFi motherboard, which provides the DDR5 slots and ECC support these 288-pin unbuffered modules need.

Will the four 32 GB modules run together with any DDR5 memory I already have installed?

Mixing kits is not guaranteed; the 2Rx8 organisation, CL46 timing and 1.10 V voltage are tuned for this specific 128 GB configuration.

How can I confirm the system is using the full 128 GB at DDR5 5600 with ECC active?

Check the BIOS memory information screen for 128 GB detected, 5600 MT/s data rate, and ECC status reported as enabled or active.
