Radeon HD 8800M on Macbook Pro doing nothing

Hey Folks,

I have an old Macbook Pro (2015) with Ubuntu on it. The CPUs are folding well, but the GPU only throws errors. I think the right drivers are installed, because the GPU is showing up in the system info of Client Advanced Control. But every time I get a WU it looks like this:

Which video drivers do you have installed? AIUI, you need the proprietary drivers from AMD, not the open source drivers.

I see several possibilities. One is that you may be missing part of the necessary OpenCL. Exactly what you need may depend on which version of Ubuntu and the source of the drivers you installed. Two is that you have the wrong kind of video driver.

What you need for Ubuntu to be usable for GPU folding is the following:

AMD proprietary video drivers
OpenCL support package for AMD
possibly the OpenCL dev kit package

Someone posted an How To for AMD and Ubuntu within the last few days, see if you can find it with a search.

Last possibility is that the 8800M in the MacBook Pro does not support Double Precision. This is a possibility as AMD released several different chips/GPUs labeled as 8800M ad not all of them support for DP, and some do.

Welcome to Folding@Home!

The MacBook Pro 2015 I find has a different Graphics chip in it.

https://www.techpowerup.com/gpu-specs/r ... tion.c2730

You did not give us the first 200 lines of your log, where we could see the configuration of your PC from it's point of view. viewtopic.php?f=24&t=26036

I am skeptical you will get it to work as you seem determined not to tell us what you have (13", 15", ?) or what it knows (configuration portion of log)

It is nice you got the CPU portion to work.

[Edit from you last post, it will not work, F@H needs OpenCL 1.2 support, and your specs list Device OpenCL C Version OpenCL C 1.1]

The report showing OpenCL running has this line:
Platform Vendor Mesa
That shows that you are running the open source Mesa drivers, not the AMD drivers. The AMD drivers would be available from their support site, or there may be a download from a repository for Ubuntu. Whether the AMD driver and its OpenCL support package will change the OpenCL level to 1.2 I don't know.
