Hi there,
Spent a few hours yesterday trying to figure out a config for 290x, alas to no avail.
So far I can't mine anything, even a bare 280x or a 290 config does not work (GPUs reset all over the place, nothing works).
And my GPUs work very well with LTC, UTC, YAC etc. So it's not a question of whether they are broken or not. They're fine.
Many thanks to whomever helps me out & take care.

How many GPUs, how much RAM and can you post a config you have tried? Perhaps somebody can spot the problem..
