I am going crazy with my two 3090s. Both run at about 105Mh/s. The MSI Triple is the primary and runs without issues, but the Gigabyte secondary either wants to spin the fans up to 100%, or throttle GPU down to 800Mhz, and crank out only 80MH/s. I have tried power limiting, GPU downclocking, and memory overclocking, however could not resolve the issue. I have a healthy Corsair 1200W power supply which previously ran 4x1070s and a single 1080 with no issues. Power draw shows 350W on the MSI, and 250W on the Gigabyte (on a riser). Both have their PCIE power inputs fully populated with clean power. Any ideas?
