I've been mining since 2.4, now on 2.7b, on a single Vega 56, W10, latest drivers, and it's been mostly fine. I've only experienced one recurring problem where mining stops (driver crash AFAIK) then restart and hangs at detecting cards for 60-80 minutes before resuming mining. Before 2.7b, my wattman overclock settings were reset to default, now with 2.7b I get to keep my settings which is much better already.
Thank you for the logs. Unfortunately we can't determine much from there just that the GPU thread is freezing after the crash. You've got quite a bit of memory overclock though maybe try dialing it back a little. We also had problems with Vega because of the card high power consumption - even 600W quality PSU led to sporadic crashes when powering a single Vega56 even with big underclock. It seems like Vega has high peak currents that lead to crashes if the PSU is not ridiculously overpowered. We have some work to do with hardware controls support for Vega though, as it appears to use some new (and undocumented) ADL functions and structures.
Ok I'll try lowering mem clocks but in the meantime do you have an idea why recovering takes 60-80 minutes in that case?
Here's another log from this morning:
