i get constant crashes in blender, apparently i need "pro drivers" for my vega64, but i dont know what they are or where to get them?

i use three vega 64s in my PC, with a 1900X CPU. for gaming, completely stable. but in blender, constant crashes. if im lucky, its just blender that crashes. this happens almost every time i try to render. but if im unlucky, i get the BSOD.

i was searching my most recent error code: "split kernel error - invalid ray state". ive had this one a fair amount in the past. i found this post with the same error, by a user with the same GPU: [Solved]Vega Blender Cycles split kernel error; In... - AMD Community

he marked it as solved and edited the post, saying "just use the pro drivers." but the only pro drivers i can find on AMDs site are for the pro GPUs, like the WXs or firepro, not the vega64.

TLDR; could you please tell me what these pro drivers are for the vega64, and where i can download them?

id be extremely grateful for the help because ive been putting up with these crashes for *years*. i have to use janky work arounds *just to open a save file* and its driving me mad. never had this problem with my 750ti, 1060sc, or 1070ti and just dont know what to try anymore. as far as i remember, this has also only been a problem with the vega64s since blender version 2.80+. 2.79- caused drastically less errors.

just install the pro driver and see.

uninstall the old driver first.

this is probably stupid, and i apologise, but i dont know where to get the pro drivers. if i go to AMDs site and follow the dropdown menus, it only lists the adrenalin drivers, which apparently arent the ones i need? the only pro drivers i can see arent for my GPU.

Professional drivers > Radeon pro drivers.

Test each one, usually they made it universal for older cards.
