Setup

BIOS Optimization for GPU Performance

Tip: The default BIOS settings may not deliver optimal performance for multi-GPU workloads. Adjust these parameters for best results:

• PCIe Settings
  Set all PCIe slots to the highest supported speed (Gen4/Gen5) and configure bifurcation for your GPUs.
  

  Advanced -> Chipset Configuration -> PCIE link width -> set MCIO2/1, MCIO4/3, MCIO6/5, MCIO8/7, MCIO12/11, MCIO14/13, MCIO16/15, MCIO18/17 to x16
  

• Above 4G Decoding
  Enable "Above 4G Decoding" to address large GPU memory.
  

  May be enabled by default
  

• Resizable BAR
  Activate "Resizable BAR" for improved CPU-GPU data transfer.
  

  Advanced -> PCI Subsystems Settings -> Enable Re-size BAR support
  

• Power Management
  Disable unnecessary power-saving features (C-states, ASPM) that may throttle GPU performance.
  Optional

• Memory Configuration
  Set RAM to rated speed and enable XMP/DOCP profiles for max bandwidth.
  Optional

• Fan and Thermal Controls
  Adjust fan curves and thermal limits for optimal cooling.
  Optional

After saving changes, reboot and monitor GPU performance and stability.
