resize bar not detected

Daftbott

I have resize bar and 4g decode enabled and connect eGPU to USB4 and directly to PCIe. I have an Arc 770 and AMD 7900. Neither of their software or GPU detect resize bar and performance is greatly reduced. Can anyone tell me how to get resize bar detected in Windows?

    Enter your motherboard BIOS, typically done with Del or F2 key (see your motheboard documentation for details)

    Enable “Above 4G Decoding”
    Enable “Re-Size BAR Support” (setting to Auto can also work)

    Enter your Boot menu, and disable CSM (Compatibility Support Module) (not available in the bios v37)


    Save, exit BIOS, and reboot into Windows

I have the same problem, my gtr7 pro 7940hs is capped...

It is also not available to activate Precision boost 2, available in bios v07, or even disable STM, in some games, you get more fps...

Hello there,
① BIOS does not support disabling multithreading and Precision Boost 2 ② AMD does not have this CSM module
