Was able to run 3 gpu ' s when 1st started in mid Aug. Now can only get RTX 3090 and GTX 1070 to run and GTX1070 will stop mining for some reason ? RTX 2080 TI and RTX 3090 only RTX3090 will mine. In mid AUG when I started mining I could run all 3 gpu's mining with all showing in task mgr , RTX3090,RTX2080 TI and GTX1070 with great Hash Rates as high as 1060.0 and averaging 450.0 plus ! Why ?
