Well, I don't know how it's supposed to work on your computer, but I do know how it works on mine and most others.
RAID has to be set outside the OS. When you turn on the computer, and RAID mode is enabled, you see a message which shows you which key you need to press. You press it and it takes you to the RAID config utility. There you can set your arrays.
Then you install the drivers for your OS. Always use the drivers provided by the manufacturer of your motherboard, not (!!!!) the drivers from amd.com.
I admit I'm a little confused about your post. You mention something called "SSD single"? What is that? You need at least 2 HDDs for both RAID1 and RAID0. If you have 1 SSD only, use simple AHCI mode, you can't use RAID features.
