I have been running GPU Grid with no trouble. I decided I would like to run Poem on the GPU but I get a GPU missing notice. What do I have to do to run it on my 2 GTX 960s. I have the latest Nvidia drivers installed.

Are you sure BOINC still sees your GPUs? It sees them when starting, in the event log?

IIRC, the Poem app is OpenCL only, so that may explain why it's seen on GPU Grid (Cuda) Your BOINC client needs to see the GPU using *both* languages. Below is one of my hosts with just a single GTX 670 in it. Notice BOINC shows it twice. It needs to see the GPU using "Cuda" for GPU Grid, and using "OpenCL" for Poem.

Got it. Did a complete uninstall of Nvidia driver then did a clean install of the latest driver. All is well now. Thanks Mumps.
