Hi,
I just installed my samsung evo 850 500GB SSD into my HP y020nd and now I would like to enable AHCI.
But there's no option in BIOS to change it.
So how can I enable AHCI?
Solved! Go to Solution.

You're very welcome.
Unfortunately, there isn't anything you can do about that.
As long as you can TRIM the drive to get rid of junk files, then that is the most important maintenance you need.

Its AHCI by deafult and you could not change it if you wished.
If you do not believe me, go to device manager and look under IDE/ATA ATAPI controllers and it should say SATA AHCI
That is all that is needed. A lot of older web tutorials on SSDs make a big deal of this but truth be told, in Windows 7 and later on a laptop with a SATA hard drive, there is really no BIOS adjustment needed for an SSD.

Hi, @Djanky :
Yes, you are correct. On AMD models, there is no AHCI description, but AHCI is the default.
You can download the AMD chipset driver file directly from AMD, explore the driver folder files and you will see reference to the sata ahci controller there.
However, for whatever reason, AMD gave the AMD Sata Controller to the device instead of AMD Sata AHCI Controller

Thank you! When I open samsung magician it says AHCI Mode activated. But at the system compatibility it still says
VID 1022
" Under the current system environment, some functions in Magician CANNOT be run. If multiple iterations of Read and Write are performed, RAPID mode may become inactive due to system internal errors on some of the AMD / AsMedia Controller or Driver.
