RX Vega + RX 580 mixed Rig - Hbcc not working - somebody made it work?

[treanski]

Hello,
i added some Vega 56 to my existing RX 580 Rig, i followed this ultimate Monero Vega Guide, flashed the Vegas to Vega 64, then i did a clean DDU Driver install.

After adding the registry mod to any Vega it becomes Error 43 in Device-Manager( ok fuck that for now)
my main problem is i cannot get this hbcc running.
what i did so far

- tried different driver(17.10.2, 17.11.4, 17.12.2)
- trigger hbcc with the slider in radeon settings
- the devcon.exe thing
- prayed to the dear god
- turn off/on by hand in device manager
- different mining software
- prayed again
- tried nearly everthing somebody mentioned on reddit to activate hbcc

im close to giving up

any advices?

Just go to device manager and disable each vega card then re-enable them one by one. Hbcc should then work and amd drivers totally suck for the record.

This trick does not work with vega frontier btw, they crash when you do this
