Yeah i insert 3060 in PCIe x16 slot, clothest to Core slot. But its still works in x4 max for some reason. Update: I unlock PCIe x16 3.0 and 41MH stock speed on GTX 3060 by unplug my GTX 1080 and leave 3060 solo in PC. But i need to reach good hashrate on GTX 3060 with my GTX 1080 in PC. Somebody know how to fix PCIe x4 on GTX 3060 when in pair with GTX 1080 on PC?
