Why turbo kernels doesn't work anymore?
I have 2 Sapphire RX 580 Nitro+ 8GB and I always got 31.5MH for each card with modded bios and clkernel -3 and -gt 39 option but now I get 2MH for each card with clkernel -3.
I used Z button to start auto-tuning process and after that my cards still have 2MH for each.
But when I switched clkernel from Turbo to Optimized kernels with clkernel -1 and used auto-tune again I get 28.9MH for my first card and 31.1MH for my second card.
I can still mine with optimized kernels but I want to know why suddenly turbo kernels not working anymore?
And also why in optimized kernels my ethermine.org stats shows every 1/30 hour my cards went to 0MH and back again after 10 minutes?
I have no idea what's wrong with my cards when they are always in maximum 65C temperature in most hot days.
