Capacity and purpose

This NEMIX RAM kit provides 64GB of DDR5 memory in a matched pair of 32GB modules. It is designed for servers and workstations that require ECC error correction for data integrity. The unbuffered UDIMM format suits platforms that do not use registered memory. IT professionals and enthusiasts building stable, high-capacity systems are the intended users.

Compatibility checklist

Verify that your motherboard supports DDR5 UDIMM modules with ECC and can operate at 4800 MT/s with CL40 timing. The kit runs at 1.10V, so the platform must supply that voltage. Confirm the board has two free 288-pin slots and that the CPU or chipset accepts 2Rx8 dual-rank modules. No heat spreader is included, so ensure airflow is adequate for bare modules.

Build integration

The two modules populate a dual-channel pair and leave remaining slots open for future expansion if the board has more than two slots. ECC functionality frees the system from silent data corruption risks during heavy workloads. The standard UDIMM height fits most server and workstation chassis without clearance issues. No additional power cables or software configuration are required beyond BIOS recognition.
