Hi guys. Trying to mine with an 290x amd card with 4gb of vram, giving an error with progminer;

"unrecognized platform intel(r) OpenCL
error no usable mining device found"

Can a 290x mine this coin? Am I missing some crucial files or is the gpu unsupported?

I think the card itself should be fine for mining. At least the VRAM is not an issue, I mine Zano with cards as low as 2 GB. But something is wrong if the miner is picking up an Intel device. If you have both Intel and AMD OpenCL drivers installed, you might need the --cl-devices option with the correct device number. Try --list-devices to find those numbers.

I tried --list-devices, made no difference, just gives me the same error message as before. This is very strange, never had any problem mining lots of different coins before with that card on my system.

I found this on issue github from searching the error message it gave you: https://github.com/ethereum-mining/ethminer/issues/2001

Might be worth trying the fix from jgonzis's comment.
