Yes, this is the problem I mentioned above. As Carlo said, it's not flawless on older R9 cards, specifically Pitcairn (78xx and 270) and Tahiti (280X, 79xx, etc.), I do find it works fine on the 285/380 (Tonga GCN 3rd series). 10.2 is important as my cards run a lot cooler with less power, but that might just be because they're churning out rubbish. I might rebuild my rigs and put all the older cards in one rig running 9.7 and all the newer, stable stuff into another and run 10.2 - sounds like a great plan but I bet I'm more likely to end up with everything broken...

Interesting that your cards run significantly cooler on 10.2. I haven't noticed any difference in temperatures and both versions of the miner run very cool: I get temps of 50-60C with my fans at 45%. Hashrate is 2020h/s running 4x R9 280x's.

The 270/X Pitcairn cards were cooler by about 10C. My office is now so hot they run at about 65-70C at 100% fans on a good day. The hashrate is also better, about 440H/s vs 400 on 9.7. Obviously this is all a moot point if they're slinging out bad data all the time.

Cryptonote is also a lot cooler than Equihash I noticed.

Finally, the Beta Blockchain drivers on Win10 took my R9 380s from 17.7MH/s to 19.5MH/s in ETH as well as making them respond properly to Power Limit controls in MSI AB so they are slightly underclocked as ETH doesn't seem core speed sensitive on those cards, it is memory speed sensitive though.
