I just come to say Thank you!!

When epoch 427 "went live" and DAG was regenerated, my 3070 started producing invalid shares; for about 8 hours, due to the overclock (using AfterBurner).  I said "there must be away to avoid this!" and proceeded to read the entire PM readme; low and behold, there was "-mcdag"!!

My PhoenixMiner (using the config file) is now fully managing my 3 cards (1070ti,2070,3070) all with individual overclock settings (no more manual afterburner OC settings application), and DAG generation is no longer a concern!
