## Bios settings ## Bios settings
These are my recommended settings that seem stable and allow GPU passthrough You can check the bios version with `dmidecode -t bios -q`
1. Memory 3200mhz, fabric 1600mhz 1. Turn off all C-State or power saving features. These definitely cause instability
2. AC Power - On like random freezes.
3. SVM - On 2. Turn off boosting
4. IOMMU - On (Do not touch rebar or other pci encoding stuff) 3. Enable XMP
5. Fans 100%
6. Initial video output: pci 3
7. PCIE slot 1 bifurcation: 4x4x4x4
8. Disable CSM
9. Fast Boot Enabled
