How 1bash file connected with number of detected cards? may be here is problem in bios, nvidia drivers or something like this? I repeat, that 12th card detected with some mistake (impossible to control funs) and problem is not in cards/raisers or motherboard physically.
Aslo I set individual powerlim
Thats why I told you to restart your rig with a fresh 1bash and see how it goes.
Have you tried the newest 1bash and Iamnotajeep/Maxximus from OP links?
