OpenCL and new drivers (windows)

[MaynardVII]

Hello,

It has been driving me nuts for a day now, but I have been issues with the latest drivers, both AMD and NVIDIA in windows.

-If I install NVIDIA drivers, it removes OpenCL for AMD.
-If I install AMD drivers, it remove OpenCL for NVIDIA.

I used to be able to install NVIDIA first, then AMD, but now I can't install one without the other one screwing up OpenCl support for the other.

It seems what has changed, is the AMD driver install process wipes NVIDIA OpenCL.

Does anyone know of a way to either-

A.) Install both, and maintain OpenCL for both platforms.
B.) Manually install/activate OpenCL for both platforms

Or am I the only person with a hybrid setup experiencing this issue?

Not having OpenCL in both platforms causes issues with Miners starting/quitting.

it seems so.

all NVIDIA miners use CUDA framework instead of OpenCL, so what's your issue here?

On the amd side, miners are failing to open that would normally open, because it states "No amd platforms found", even though clinfo list amd as a platform.

Also, some miners, like sgminer and wildrig are failing to shutdown, and lock up. Nvidia side works fine, however.

This is a test rig, I run miners for software development. It only has 1 nvidia card, 1 rx580, and 1 Vega on it.

Removing the vega from the equation- the miner closing issue goes away, but the "no amd platforms found" for ethminer-stlyed miners still exist, when arguments are correct, and amd clinfo command list amd platform.

I have been searching for causes, and it hit me that clinfo prior to having all the problems used to list both platforms. Thats when I realized that the driver installs keep removing the opposite opencl platform on each install, and it didn't before when I remeber the last time everything was working.

in my case clinfo lists 3 platforms - Intel, AMD and NVIDIA. I'm using the latest NVIDIA driver, and Adrenaline 18.6.1 driver for AMD. both NVIDIA and AMD miners work without any issues.

I've never tried the new 19.x AMD drivers, maybe you should try to install one of the previous AMD driver builds to check if the issue will persist?
if no then it's a bug with 19.x release,
if yes then maybe something is not right with your Windows.
have you tried to use DDU and clean install both drivers then?

Avoid multiple drivers!
