I own now 2x Sapphire 5700XT.
I have used Adrenaline 1.9.2.2 and classic setting posted on this topic;
-tt 62 -cclock 1300 -cvddc 800 -mclock 900 -hstats 2 it gives 52,x MH but it fails in minutes.
I have tried lower or bigger -cvvdc between 750 and 900mV, even lower/higher -tt, it fails randomly showing 0.00MH.
I tried also to keep memory stock (875MHz), it fails randomly, same problem and miner stays locked, mouse too, just hard reset works.
When I have removed
-hstats 2 command, keeping just
-tt 62 -cclock 1300 -cvddc 800 -mclock 900, it worked fine 12 hours but I just tried last sollution: I have deleted all commands
-tt 62 -cclock 1300 -cvddc 800 -mclock 900 -hstats 2 from ,bat file and I have used
just Msi Afterburner 4.6.2 beta 2 https://www.guru3d.com/files-details/msi-afterburner-beta-download.html wich full controls power limit, voltage and frequency, now I left voltage unattended (1187mV), GPU frequency stock, memory increased at 900MHz and power limit
down to -43 or even -44%.
Works flawless.
It looks as the much commands gived to the miner (tt 62 -cclock 1300 -cvddc 800 -mclock 900 -hstats 2), especially -hstats 2, gives driver error (atimtag.dll) and locks the miner...
So, I keept settings as in picture attached and .bat file as simple, without extra commands ex:
PhoenixMiner.exe -pool ssl://eu1.ethermine.org:5555 -pool2 ssl://us1.ethermine.org:5555 -wal your wallet adress.rig name, and is rock solid.

While we use the AMD provided API to do most of the hardware control and monitoring, most of these programs use lower-level undocumented access and doing both at the same time can lead to driver lock ups. Note that Afterburner must be completely closed, not only minimized to tray in order to stop interacting with the GPUs. Or, alternatively, you should use only Afterburner (or other third party program) and none of PhoenixMiner hardware control options.
