My modified AMD driver doesn't work with my Ryzen 5 5500U - why?

Operating Systems Windows 8/Server 2012

Hello, I’m new to this community. I have a Laptop that has an AMD Ryzen 5 5500U and I modified the Adrenalin driver (20.4.2) INF file and I installed it in Device Manager but it seemed that It was gonna work but it didn’t. It gave me Error code 43, did I do something wrong?

Hi, i first have one question : what are you trying to do by modifying the driver ?

You modified the Adrenalin 20.4.2 INF file for your Ryzen 5 5500U, but Error Code 43 means the driver couldn’t start. That’s probably because:

  • The driver is too old, so it doesn’t have the right binaries for your iGPU, even if INF modding forces the install.
  • Windows might be blocking unsigned drivers unless you disabled driver signature enforcement.
  • Even if it installs, the kernel-level drivers like atikmdag.sys probably don’t support your iGPU hardware ID.

Try modded drivers like NimeZ, that’ll probably work.

Could also give more info like the inf file itself ? Because it’s a bit difficult to help with just theses infos.

I’m trying to change some hardware ID from any GPU in that INF File so i can try to see If it works or not. eg. im gonna change the hardware id from the inf

"%AMD6610.8%" = ati2mtag_R501, PCI\VEN_1002&DEV_6610&REV_81

and replace the Hardware ID to mine.

"%AMD6610.8%" = ati2mtag_R501, PCI\VEN_1002&DEV_164C&SUBSYS_3F9517AA&REV_C2

That’s all, also if you mind me linking the driver in DMs?

If the driver itself (= the *.sys file) doesn’t support the related device or OS, the simple insertion of the missing HardwareIDs into the related *.inf file doesn’t help (not even, if the modded driver has been correctly digitally signed).
You can test whether a certain driver supports a certain device by forcing the driver installation. This can be done from within the Device Manager by hitting the “Have Disk” button and navigating to the original driver files.

Well I did that too but it didn’t work, I think the reason why the drivers didn’t work is because it was supposed to support WDDM 1.3/ or 1.4, not sure about it. But Vega 56/64 and my Vega 8 are after the same GCN 5.0 architecture.

UPDATE: I managed to sucessfully install the drivers and I used Adrenalin 22.6.1 that is meant for Windows 7, but when I installed it, It was flickering black 5 seconds but then it shows a white screen.
