Graphics Cards

[0xE1]

I was installing older drivers to try and find the version where CrossFire was still available as option,

after installing 20.1.4-Jan27 I noticed that system was showing me Radeon Pro WX 7100 now instead of Radeon Pro Duo.

With that, there doesn't seem to be any way to get it reporting correct model name...

Next week @fsadough can explain why it is showing as WX7100 GPU card instead of Radeon Pro Duo (Polaris).

But looking at one of the previous Professional Drivers that supports Multi-GPU still this is what it mentions: https://www.amd.com/en/support/kb/release-notes/rn-pro-win-19-q1-1

Since Multi-GPU on Windows 10 is supported only on the WX7100 maybe that is why it shows your GPU card Duo Polaris as a WX7100. just guessing though.

Hi,

I cannot find any Jan 27 driver release. Please provide an URL to the driver. Regardless, what are you trying to do?  You already have a dual Polaris chip on your Radeon Pro Duo. Keep in mind Cross-Fire must be supported by the application as well, otherwise you will not be able to use it.

Please explain in details, what you are trying to do and what application you are using for CrossFire.

That's the release I believe that I installed after which the GPU name have changed: https://www.amd.com/en/support/kb/release-notes/rn-rad-win-20-1-4

Full file name is Win10-Radeon-Software-Adrenalin-2020-Edition-20.1.4-Jan27.exe (which is where I took the 20.1.4-Jan27 part from)

Main concern is to get the naming back,
secondary I wanted to test how Crossfire worked and then see how MultiGPU performed with same software.

In total I installed all of these:
21.10.2 (just updated to the latest drivers first)
20.8.3 (first choice was to a year older version as there was a post somewhere that August driver was last to have CrossFire option)
20.8.2 (second choice to see maybe I was one version off as there was still no Crossfire)
20.1.4 (next option to beginning of previous year to see if it's even within that year)
19.2.3 (next option to beginning of one more year, which is where I have then seen that installer is showing me wrong GPU name)
I then installed 21.10.2 back, but it was also showing different GPU name, DDU didn't help, nor moving GPU to different Windows machine, even Linux was showing me WX7100 in dmesg now.

If your concern is to get the naming back, I suggest you install the PRO driver instead of Adrenaline driver. In the Adrenaline driver you mentioned the Radeon Pro DUO with the Device ID 67C4 is listed as :

• "%AMD67C4.1%" = ati2mtag_Polaris10, PCI\VEN_1002&DEV_67C4&REV_00
• AMD67C4.1 = "AMD Radeon (TM) Pro WX 7100 Graphics"

Whereas in Pro driver you will see the Device ID 67C4 as:

• "%AMD67C4.1%" = ati2mtag_Polaris10, PCI\VEN_1002&DEV_67C4&SUBSYS_03361002&REV_00
• "%AMD67C4.2%" = ati2mtag_Polaris10, PCI\VEN_1002&DEV_67C4&SUBSYS_13361002&REV_00
• "%AMD67C4.3%" = ati2mtag_Polaris10, PCI\VEN_1002&DEV_67C4&SUBSYS_075D1028&REV_00
• "%AMD67C4.4%" = ati2mtag_Polaris10, PCI\VEN_1002&DEV_67C4&SUBSYS_175D1028&REV_00
• "%AMD67C4.5%" = ati2mtag_Polaris10, PCI\VEN_1002&DEV_67C4&REV_00
• AMD67C4.1 = "AMD Radeon(TM) Pro Duo"
• AMD67C4.2 = "AMD Radeon(TM) Pro Duo"
• AMD67C4.3 = "Radeon (TM) Pro WX 7100 Graphics"
• AMD67C4.4 = "Radeon (TM) Pro WX 7100 Graphics"
• AMD67C4.5 = "AMD Radeon (TM) Pro WX 7100 Graphics"

That is very good observation,
I was not aware that Adrenalin driver is not exactly same as Radeon Pro, since it did in the end install Radeon Pro software, so I believed that the end result was nearly the same (with difference perhaps in driver being slightly newer and not WHQL).

I will try this in a few hours and will report back, this looks promising and would explain this behavior if it works!

That was definitely it,
running Radeon Pro driver installer did show GPU with incorrect name due to existing drivers,
run DDU to remove everything,
running same installer afterwards - already showed the correct GPU name, and after installation it's showing up correctly everywhere!
