ASRock EPYCD8-2T compatible server kit

This 128GB kit contains four 32GB DDR4 3200 ECC RDIMM modules built for ASRock Rack EPYCD8-2T series motherboards. Registered buffering and on-die error correction protect data integrity in multi-socket server workloads. The kit is validated for 1.20V operation at CL22 latency.

Verify DIMM slots and population rules

Confirm the motherboard has four free 288-pin DDR4 RDIMM slots and review the EPYCD8-2T manual for approved population order. Registered ECC modules require platform support for registered buffering and ECC; consumer boards without that support will not post. Ensure BIOS is current before installation.

Modules ship without heat spreaders

The 2Rx4 modules rely on chassis airflow for cooling; no spreaders or active cooling are included. Packaging provides only the four memory sticks in anti-static trays. No configuration software, LEDs or additional accessories are bundled.
