It’s in regard to OpenGL support, not OpenCL/Cycles.

Still, make sure to check your preferences, system subsection.

Didn’t understand can u pls elaborate

Navigate the menus: edit - preferences. A new window appears, find the button that says System. Press it, and see that towards the top of the window there is a enumerated selector for Cycles Render Devices.

Of course dude I have checked it millions of times… It doesn’t recognise my card whereas is should… Sheepit can use my card for rendering through blender. Then how is it that my blender doesn’t recognise it ?

The highest openCL version supported by your driver is likely too old.

7

So just to be sure… What is the lowest possible version of open CL that supports blender so I can re check mine

Depends on the blender version. Heres the documentation for latest stable(as of this time):

https://docs.blender.org/manual/en/latest/render/cycles/gpu_rendering.html#amd

OpenCL is supported for GPU rendering with AMD graphics cards. Blender supports graphics cards with GCN generation 2 and above. To make sure your GPU is supported, see the list of GCN generations with the GCN generation and supported graphics cards.

AMD OpenCL GPU rendering is supported on Windows and Linux, but not on macOS.
