I think I finally have it all figured out. I was previously using corectrl to monitor and adjust the GPU but lact has so much more info and adjustment. I immediately saw the card flapping between clock speeds under load. I applied the only high clock speeds setting and that all stopped the voltage stayed constant. However and this is why I didn’t realize with corectrl is that the card was now thermal throttling causing an undervolt condition. I went in cleaned out the dust bunny’s, dislodged a sata cable from one of the fans and relocated some hard drives for more airflow. The card now runs at a toasty 85 under load which from my past amd experience is perfectly fine. Thank you for the help kind stranger.
