generic desktop PC /w RX5500XT + eGPU Problem
i have radeon VII with razer core X eGPU. and, recently i have upgraded my desktop pc with radeon RX5500XT. because i use windows and linux in this desktop. nvidia's cards has many problem even using it as a dGPU (attached it motherboard's PCIe slot).
before i use macbook pro with this eGPU, i has many ploblems. install bootcampdriver's driver, swap PCI.sys file. but, this problem cannot find in web.
Maybe it was right to buy an nvidia graphics card?
please help me. and thank you very much
AMD ryzen 7 3800X

@gzx9755 What's the model of your Desktop PC motherboard? Look into doing a DSDT override to fix error 12. You can also check the BIOS and see if there's Thunderbolt settings you can change to resolve error 12.
oh sorry. i edit my post but i'm rate.
i using asrock X570 Phantom Gaming-ITX/TB3. BIOS version is 2.0.
where i can change thunderbolt settings? i using only intel's thunderbolt software.
and, i will try DSDT override tomorrow. Thank you!
i'm sorry for late.
after i back to home, i tried disabled Legacy CSM support, and enabled Above 4G Decoding. and, confirmed 'large memory entry' after reboot (cold reboot) but my radeon VII still error 12 status. i tired clean uninstall GPU drivers with DDU (with cold boot), but still error 12 status.
i failed 🙁
i have 'large memory entry' already, but i cannot connect my vii. DSDT override can have effect even my case?
always many thanks.
@gzx9755 Your steps seem to have replicated what @ningauble77 did in his build. The only exception is your RX 5500 XT dGPU vs the APU in his. My next recommendation is to do a clean install of Win10 1903 V1 to see if it helps. I know you mentioned a pci.sys swap but it's worth a shot.
Another Fail... first, i check legacy csm support and above 4G decoding setting in bios. after i check, clean install windows 10 1903, install thunderbolt 3 driver, install amd driver.
but still i see error 12 status. 🙁
there is another thing i can do?
always many thanks
Nope its the 5500XT (owning the same) itself, or how AMD installs the driver.
I can reproduce the working Card, but only until reboot.
Uninstall the Card wiith option >> Delete Device Drivers, do it until no more Drivers are loaded by windows and disconnect internet, best is AMD Driver Cleaner.
No start AMD Setup, choose Option >> Default Settings, let it do, reboot and for me after reboot, the Card worked as expected - but only until reboot....
