Have you tried updating the bios on this motherboard?

Yes! I am currently using 7A75v12 (https://www.msi.com/Motherboard/support/Z270-GAMING-PLUS.html)
Does it have to be in a special latency value? It is set by default in 32b. Pcie gen 1 o 2? UEFI o Legacy?
I've tried many permutations, all the same problem.

I've been trying with 4 GPU.
With disabled above 4g memory, only 3 GPUS are detected in most cases (sometimes all of them are able to mine)

I don't have one of these mobos; not sure what bios setting are needed.

Does anyone have one of these mobos and know good bios settings?

I've this on the MSI official web page: https://drive.google.com/file/d/0B-Z98LONNR0hTGM0Y0ViR0VXS2c/view
Its made for windows, how does it apply to your OS?

See the nvOC OP for that mobos required bios settings.
