r9 280x UEFI-Mode

Hello guys, i was wondering about the Dual Bios switch supported by the r9 280x Toxic. The manual indicates, UEFI-Mode ist accessed by pressing down the Bios switch (switch emits blue light), though GPU-Z is telling me, UEFI-Mode is deactivated, while the switch is pressed down? Is this a display Error by GPU-Z, or did it somewhat misunderstood the manual?


PS: The picture shows the UEFI-Mode, while the switch is in an upward position.

 

UEFI vs Legacy boot mode

Switching to UEFI bios on GPU does not enable UEFI mode if motherboard is set CSM = On. Setting CSM = Off in my experience causes Windows 7 issues, even if installed as UEFI mode with GPT partition on storage device.

• Press Windows key + R.
• Type services.msc, then hit Enter.
• Search for Radio Management Service.
  
• Right-click, then choose Start.

Note: Never ever set this service to "Disabled".
