(moderation:
I got a new (old) GPU, AMD R9 290X, which is running fine on Milkyway, PG, and even FGRPB1. But when running O3AS, I get only Validate Error, or marked as invalid.
Here is a Link to all of my invalid WUs.
Maybe somebody has an Idea.

I suspect this may be because the hardware (GCN 2nd generation -- Hawaii) is rather old.
I know for certain that GCN 1st gen cards (eg. Tahiti) do not work because I tried one quite a while ago. I don't have any 2nd gen cards to test so can't say for sure. However 1st and 2nd gen were reasonably similar so I wouldn't be surprised. I have 4th gen cards (Polaris) and they work fine.
The staff don't have a lot of different cards (particularly older ones like yours) so I don't think they will know for sure either. Perhaps someone else may have a 2nd gen card and can advise if it can work.
I use Linux only and would run clinfo to check the OpenCL version and capabilities of the card. I imagine there might be a similar utility for Windows that you could run?
Cheers,
Gary.
