128GB DDR5 ECC UDIMM kit

This NEMIX RAM kit delivers 128GB of DDR5 ECC unbuffered memory in a matched set of four 32GB modules. It is built for ASUS Prime A620, B650 and Q670 motherboards that require error-correcting code for data integrity. Workstations and entry-level servers handling critical datasets gain the capacity and reliability they need.

1.1V operation at 5600 MT/s

Each module runs at the standard DDR5 voltage of 1.10V with a CAS latency of CL46, keeping power draw low while maintaining 5600 MT/s throughput. The unbuffered design avoids the extra register latency of registered DIMMs, and the absence of a heat spreader means the modules fit in tight DIMM slots without clearance issues.

Upgrade from non-ECC or lower-capacity DDR5

This kit replaces standard non-ECC DDR5 when silent data corruption cannot be tolerated, or smaller ECC kits when workloads exceed their capacity. The jump is worth it for users moving to 128GB who need both the error correction of ECC and the density of four 32GB ranks on supported ASUS platforms.

Questions about this item

How do I install the 288-pin DDR5 ECC UDIMM modules on the ASUS Prime A620M-A-CSM motherboard, and what step is often missed?

Align the notch on each 288-pin module with the slot key, press firmly until both retention clips click, then enable ECC in the BIOS — the last step is frequently skipped.

What maintenance or replacement will the 128GB DDR5 5600 CL46 kit need over time?

No scheduled maintenance is required; if a module fails it is replaced individually under the lifetime replacement warranty.

What limit appears first when the 1.1V 2Rx8 modules run sustained workloads?

The CL46 latency at DDR5 5600 sets the throughput ceiling before voltage or thermal limits are reached.
