Questions and answers
как включить две видеокарты
To enable two graphics cards on the ASROCK B450 Pro4:
1. Insert each graphics card into separate PCIe slots.
2. Ensure that both PCIe slots are functioning by testing each with a single card.
3. If one slot is not working with both cards installed, try switching the positions of the cards.
4. In some cases, moving an NVMe SSD from one M.2 slot to another (e.g., from M2_1 to M2_2) may resolve conflicts with PCIe lanes, allowing both GPUs to be recognized.
5. No CrossFire configuration is needed if using multiple GPUs for additional display outputs only.
6. Check BIOS settings for any options related to PCIe slot configuration or GPU initialization, but default settings often work.
If the system still does not display output with both cards, test each card and slot individually to isolate issues.
