64 GB DDR4 ECC UDIMM kit

This NEMIX RAM kit delivers 64 GB of DDR4 3200 ECC unbuffered memory in four 16 GB modules. It targets system builders and IT professionals who need error-correcting capacity for compatible ASRock motherboards and workstation platforms.

Straightforward 288-pin installation

The modules install like standard UDIMMs and require no special tools. Common issues arise when the motherboard BIOS lacks support for ECC unbuffered DIMMs or when all four slots are populated without verifying the platform's maximum memory speed at full load.

Suited for ECC-capable ASRock platforms

Builders needing registered or load-reduced DIMMs, non-ECC consumer memory, or DDR5 speeds should look elsewhere. This kit also does not suit boards limited to single-rank modules or voltages above 1.20 V.
