Catalyst (Crimson) 15.12 is required for best performance and compatibility. You can get very bad results for different drivers version, or miner can fail on startup.
For me this was not true, it was the crimson 15.12 drivers causing the miner to crash. I'd tried every troubleshooting trick in the readme to no avail and even asked in these forums, nothing worked. If your miner is crashing or If you are having stability issues update to the latest relive drivers from AMD.
I was really confused on this one because I have two identical Optiplex 390 machines, both running windows 10 pro, both with newest A11 bios, both with onboard video enabled too, both with 8 gb of ram, and both with R9 fury's in them. One has been running flawless for almost a month and the other wouldn't run at all. I'm sure I used the 15.12 drivers on the machine that was working when I set it up, but that was in the earlier days of claymore (9.0) and I must have left the automatic driver update option checked. Some change made between 9.0 and 9.2 causes issues with the 15.12 drivers on certain rigs.
Just to be thorough I removed the newest drivers on the optiplex that has been working and installed the 15.12 drivers and zecminer64 would crash right after card detection every time. Updated to newest drivers with clean install option and it's working again.
