I am running Windows 10, trying to get my SSD switched to AHCI from IDE after I have already installed windows on it. I currently have it connected to SATA port 6. I have several other regular hard drives on SATA0-4.

Picture of my BIOS options and motherboard info

I have tried a couple of the methods, including editing the registry and using command prompt. Both can be found in this Windows 10 help thread.

Editing the registry didn't do a thing. When I attempt the command prompt method, I get a BSOD upon re-starting after changing to AHCI.

I'm also not even 100% sure which values I should be changing to AHCI in my BIOS. From what my MB guide shows, I would think I have my boot SSD in GSATA3_6 as that is a 6gb SATA connection, based on the BIOS options available. However most people suggested using SATA0 for their boot drive, though I am guessing they have a newer MB than me. This was the only value I was switching over from IDE to AHCI.

I am unsure if I should be switching any other values, or if it would make a difference. Such as eSATA ctrl mode or SATA3 Firmware Selection.

I am getting terrible benchmarks on IDE with my SSD so I would really like to figure out what is going on here.
