Compatible DDR4 ECC UDIMM for ASUS ROG Crosshair

This 8 GB DDR4 module runs at 3200 MT/s with CL22 latency and ECC protection. It is built as an unbuffered UDIMM using a 1Rx8 organisation and operates at 1.20 V. The part is validated for the ASUS ROG Crosshair VIII Hero motherboard based on the AMD X570 chipset.

Thermals noise and power draw

The module has no heat spreader and draws power only from the DIMM slot at the standard 1.20 V DDR4 level. Passive cooling relies on normal case airflow across the PCB. No active cooling or additional power connectors are required during typical operation.

Build integration and slot usage

The 288-pin UDIMM occupies a single DDR4 slot and adds 8 GB of ECC capacity without registering or buffering signals. It leaves remaining slots free for further expansion up to the board limit. The 1Rx8 layout keeps electrical loading low for stable signalling at 3200 MT/s.

Questions about this item

How do I install this 288-Pin DDR4 ECC UDIMM in the ASUS ROG Crosshair VIII Hero X570, and what step is often missed?

Align the notch on the module with the slot key, press firmly until both retention clips click shut, then enable ECC in the BIOS — many builders forget the BIOS step.

What maintenance or replacement will this CL22 1.2V module need over time?

No scheduled maintenance is required; the module either runs reliably for the system's life or is replaced under lifetime warranty if it fails.

What limit appears first when this 1Rx8 3200MHz stick runs sustained workloads?

The CL22 latency at 1.2V is the primary constraint; bandwidth scales with CPU and motherboard capabilities rather than the module itself.
