Using R-Mode with 5700(XT) Seems to be quite unstable, at least for me..
EDIT: Even RX580 keeps crashing, totally random with cards, Rig was stable 9 months with LoL and now with TRM crashing all the time.
Maybe i will change back, i lose 100w but get stable rig...
Change your OC. If the OC work with lolminer is not meaning it will work with TRM. Go to discord channel and ask the devs, but mostly the problems is in front of the monitor

Usually, but not worth the fight for couple eurocents.
