Dual Mining ZIL Causes Dead GPUs #338

Dual mining ZIL by passing the -zil parameter at the end of the ETH command causes dead GPUs. TRM is able to mine on Ethermine and even switch to Ezil, but when it tries to switch back to Ethermine my 6700 XTs both show as dead GPUs. The 5700 XT is able to continue hashing (verified by removing --watchdog_script).

teamredminer.exe -a ethash -o stratum+tcp://us1.ethermine.org:4444 -u . -p x --enable_compute --watchdog_script --zil -o stratum+tcp://us-east.ezil.me:5555 -u .. -p x --zil_end

I tried using eth_config=A just to see if the B mode was getting in the way somehow as mentioned that B mode does not work in releases less than 0.8.3. Mote only 5700 XT is running B mode. 6700 XTs are running in A mode.

Mining directly on Ezil allows for dual mining via:

teamredminer.exe -a ethash -o stratum+tcp://us-east.ezil.me:5555 -u .. -p x --watchdog_script

Tested on Windows 10 with latest AMD drivers. 5700 XT does have bios flashed. 6700 XTs are undervolted, fast timing enabled, core clock reduced, and memory overclocked via AMD Radeon Software. Everything is stable when running directly on Ethermine or Ezil.

Same problem for me with the RX 6700 XT, the other RX 6800's are working fine
