Just tried this with my 5700 XT. Underclocked all the way down to 1600 (1605 advertised base clock on reference model) from 2150 ish. Crashing went from every 5 min to about 10 min. Unfortunately, still unplayable.
I get constant crashing. Sometimes location dependent and %100 repeatable and sometimes seemingly random an not repeatable. I've gone through this forum in hopes of a fix or workaround but none of the solutions I've found work.
