FAQs

Q: Can I use this kit with fewer than four MI210 GPUs?
A: This kit is intended for 4-way MI210 configurations. For two GPUs, use a 2-way bridge model.

Q: Does the bridge change PCIe lane allocation?
A: No. It provides direct GPU-to-GPU links and does not alter host PCIe lane assignments.

Q: Do I need special drivers?
A: Use up-to-date drivers and ROCm versions that support MI210 peer-to-peer communication.

Q: Is this compatible with mixed GPU families?
A: Use with matching MI210 GPUs for proper operation and performance.

Q: What server considerations apply?
A: Confirm mechanical fit, required airflow, and that your chassis supports 4x MI210 with bridging.
