Cycles opencl is instable

Hi i am new here

I need help

I have a system with double Radeon VII

When i want to render volumetrics (smoke sims) the render will stop and blender will crash. Theres no crash log it just stops rendering and you have to close it via task manager

I have the newest windows
The issue is in all blender versions
I have the newest drivers
Crossfire is disabled (it makes no difference)

Its only when i select the radeon as opencl divice with my 9900k there are no problems

The cards are definitely stable only blender isnt

Do you know how to make them work correctly
