Gigabyte 890GPA-UD3H

Hi, Does anyone know how many 320GB drives I can put onto the motherboard to boot into WIN10x64 ? I put 6 onto Intel ICH9R but not sure of AMD SB850.

You should look into your mainboard manual to get the exact answer, but I think, that only the amount of available AMD SATA ports limits the amount of attachable SATA HDDs/SSDs.
For the OS Windows 10 it is no problem at all to support 6 disk drives.
By the way: What is the sense of your question? Why do you want to attach so many 320 GB sized disk drives to your mainboard? Do you want to create a RAID array with them ? If yes, which sort of RAID? You probably know, that you will not get an unlimited speed-up of your your system this way.
