Because if only one card - one team, right?\r\n\r\ndefault: -1 I imagine is how the miner tries to identify your graphics cards - and in which Team they are in - people with the big mining rigs you see pics of with (for example) 3 x identical RX480 cards... And below those three cards there is one slot left and it is an old GTX 960. Your Computer is going to assume that the three nice RX480's are a team (PLATFORM 0, or 1) - and the lonely little Nvidia card, yep, Team 2 (PLATFORM 1).\r\n\r\n\r\nTLDR:\r\n\r\nexperiment with --gpu-platform 0, and nothing else - if you get an ERROR that asks you to _choose an OPENCL PLATFORM_  - THEN - you have the correct platform.\r\n\r\nSo - you choose a team: platformid 0\r\nthen you choose the players that you want to use (DEVICE ID)\r\n\r\nFor example - I have 1x AMD and 3x Nvidia - AMD is platform 0.\r\n\r\nNvidia is platform 1.\r\n\r\nI would do:\r\n\r\n--gpu-platform 0 (AMD card location, top PCI-E slot)\r\n--device-id 1 (the AMD card in platform 0)\r\n\r\nif I had three Nvidia cards underneath those, all lined upn I'd write:\r\n\r\n--gpu-platform 1 (Team nVidia/PCI-E slot #2)\r\n--device-id 0 1 2 (graphics card 1, 2 and 3)\r\n\r\n- you must specify a team, and then a player. (platform, then a deviceid)"}}
