I tried an ASUS H170 Gaming board and only 3/6 slots worked.
4/6 was possible depending on the right slot assignment and UEFI Setup configuration but it wasn't really stable under mining load for longer periods.
5/6 was a disaster: the misbehaving SATA controller caused data corruption on the root filesystem up to the point where Windows became unbootable.
6/6 was better, it didn't even get through the firmware initialization, so it had no chance of corrupting data on the SATA drive.

I took it back to the store and left with a 6-slot Gigabyte Z97 Gaming 3 (v1.1) because they had one of those at stock. It works great so far (and it looks like a decent PC mainboard unlike those 80/90-series 6-slot Asrock boards, so it might be easier to sell when the time comes...).

Hey thank you so much for answering, I'm having almost the same issues with my MSI z170-A pro. But what I find really interesting is the fact that the last batch of asrocks h97 anniversary that I bough (six of them from some amazon vendor called outlet pc or something like that), were presenting the same faulty sata behavior, but they did it when I put the 6th gpu on the system. windows sometimes didn't want to boot and the solid state disk wasn`t able to pass the seatools tests as long as you had the 6 gpu connected and the system managed to boot. If i did unplug one gpu or put the solid state disk on another mother board of the same model but a previous batch the disk did pass all the tests.

So i really like to know what causes those faulty sata behaviors, or how to stop them and at the same time keep using the 6 gpu

I wonder if genesis mining use those regulars MB or if they use some custom made Motherboards and uefis.
