Anyone know why Phoenixminer lowers the core clockrate on some GPUs (and not others of the same model on the same rig) after they start up and successfully hash at ~50 MH/s for a few minutes? I am starting all my RX 5700s at 1300/900 (core/memory) and they all start out at ~50 then for some reason PM lowers the clock rates on some which end up hashing at around 40 MH/s or less. I am setting GT value at startup so it's not auto-tuning. Any thoughts?

Have you tried letting it autotune? ive noticed that sometimes the hardsetting of GT values results in lower hash on subsequent boots. Since most of my rigs are stable i dont bother setting and get consistently high hashes. 53-54mhs without bios mod on 1350/920/775. With bios mod about 56.7mhs per 5700xt...but i need to spend some time tuning them...57-60 should be achievable.
