just use latest drivers but you should use nbminer much better , pheonix is a bit crap now dont support new rtx cards a lot of it is buggy plus the hashrate reporting is dubious on it too , they need whole new upgrade on it really used to be good but theres much better out there now.
Yea, I've see a lot of reports about those type cards and issues. Fortunately for me, I started mining years ago and got all AMD cards at a pretty good price back then and those were some of the first cards Phoenix supported. So it seems for those cards most all the bugs were eliminated a long time ago. For me I don't have any of the issues reported by other cards, and I don't plan on purchasing any more cared at this point.
