Hello, I am still facing the issue that in my setup, nVidia cards with Pascal chip lose the OpenCL abilities. It happens with an nVidia of the last verison. I wrote this in another thread, now this issue is becoming a greatet issue, since nVidia drivers 417.71 are needed for G-syncing with my Freesync monitor.

So I would need help:

1) Does anyony know about the problem?
2) Do you experience the same problem with the newest nVidia drivers?

 

OpenCl for nVidia drivers 388.81 No OpenCl with nVidia driverrs 417.71
GPUZ 388.81
GPUZ 417.71

Yes, I have alread adressed this problem with this OpenCL is Lost. It's driver 416.81 which eliminates OpenCL for nVidia cards on certain MacBookPros.
Until now, the workaround was not to upgrade drivers, but this is not a good solution anymore.

@itsage, do you have any intel about this problem?

 

EDIT: Thanks you @mac_editor, a correlation between the issue and AMD drivers has been found. On a system where all current AMD drivers have been removed, nVidia cards still can do OpenCL with newest nVidia drivers (left). After plugging in an AMD eGPU this feature automatically vanishes (right). Note, that fully initialized AMD cards still can do OpenCL.

Unfortunately I don't have any official info on why OpenCL doesn't work on some Nvidia cards with the latest drivers. I hope this is a bug. I've seen this "No OpenCL" in AIDA64 too with the latest drivers.

I'm not sure if it's a machine issue with the 417.71 drivers as I can get OpenCL with my 1070 Ti with 2014 Mac mini.  I did have issues before where the CUDA wasn't showing up until I reinstalled the latest drivers.

It may not be related to a particular nVidia card, as on my 13-inch MPB 2015 I can't remember having those problems. I  found a Screenshot of GPGPU, but it was with older nVidia drivers, so I will have to recheck it.

For my 15-inch MBP 2018 it's reproducible with every Pascal card I tried: OpenCL ceased working with nVidia driver 416.81.

@omardesu, thanks for this input. This hardens my suspicion that the issue is related to particular MacBook-models. CUDA is a different thing, it still is working at my system, too.

I ran into this issue recently, with no OpenCL capabilities from either nvidia or intel drivers.  In my case it was caused by leftover registry entries from an older intel driver.  

I went to:

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Khronos\OpenCL\Vendors

and 

HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenCL\Vendors

And deleted the entries there related to intel OpenCL drivers.  After a reboot I get OpenCL for both nvidia and intel now.   Be sure to back up these keys before deleting them, in case it isn't the same cause.

With a GTX 780 Ti it's the same problem. This is becoming really disturbing.

Nvidia gpu's lost Opencl capability if used into an eGPU setup?

Knowing Nvidia it is mostly what's happening, i would suppose.

If the gpu is plugged into a desktop, the result would be different with Opencl capability enabled.
Because i did not heard any issues about desktop side.

So please edit the thread title to be more precise, because it could be misleading for the forum users.
Not that AMD/Nvidia could not be extensively blamed for their bad consumer behavior, but i suppose if this issue is happening it relate mostly to the eGPU side!

Ah, I see... we eGPU users have to take the blame that OpenCL doesn't work anymore with nVidia cards in eGPU setups. We all should reconsider our behaviour.

Nothing surprise me anymore, that's why i'm always open to all possibilities to start with.

But at the moment, i did not heard anybody complaining about Opencl issues in programs.
Do you have actually software issues related to Opencl?

To me if there are no real issues, it could be either an issue that happen only in your case or a gpu-z bug when launched from an eGPU setup.

If you had read this thread with the necessary attention in order to criticize, you would know that the OpenCL ability is not only missing in GPUZ.  GPGPU applicatons won't work anymore, . @itsage has this problems, too.

Because this is a serious matter, I am willing to post another screenshot:

NoGPGPU

Edit: Reverting the driver to 399.24 brought back the OpenCL abilities.
