64 GB DDR4 3200 ECC kit for ASUS X570

This NEMIX RAM kit provides 64 GB of DDR4 3200 memory in four 16 GB unbuffered UDIMM modules. Each stick runs at 1.2 V with CL22 latency and includes on-die ECC for error correction. The 288-pin modules are validated for the ASUS ROG Crosshair VIII Hero motherboard on the AMD X570 platform.

Suited for ECC-capable workstations.

Builders who need data integrity on a compatible ASUS X570 system will benefit from the ECC function. Systems that cannot enable ECC in the BIOS or that require registered DIMMs cannot use this kit. Buyers seeking higher frequencies or lower latencies should look elsewhere.

Four-slot population on a validated X570 board

The kit fills all four DIMM slots on the supported motherboard, delivering the full 64 GB capacity without mixing modules. It operates at the standard 1.2 V DDR4 voltage, leaving headroom for CPU and GPU power budgets. No heat spreaders are fitted, so airflow around the slots remains unobstructed.

Questions about this item

What motherboard slot count and DDR generation must my board provide for this 288-pin DDR4 kit?

The kit requires four 288-pin DDR4 DIMM slots; each module is a 16 GB unbuffered ECC UDIMM.

Will the CL22 timing and 3200 MT/s speed run automatically with the X570 platform?

The modules operate at 3200 MT/s with CL22 at 1.2 V; enable the XMP profile in BIOS to reach the rated speed.

How can I confirm the 64 GB ECC capacity is active after installation?

Check the BIOS memory summary or OS tools — they should report 64 GB total and show ECC enabled.
