ACHI drivers for W8.1 with amd
- by LeiNaD_87
I hope you can help me...
I just installed a SSD (Samsung EVO 840) and windows 8.1 pro in my pc with M5A99X EVO ( chipset AMD 990X/SB950 ) motherboard.
The SSD is installed in sata3 socket using a sata3 wire. The AHCI mode is ON in the bios. I configured the ahci controller and now device administrator looks like this:
All works, but the speed of the SDD is very slow (like a HDD). Samsung magician doesn't recognize the sata mode neither the ahci. I tried to install more drivers but the system broke and I need to reinstall windows :(
I tried many things from the web, but any works:
Modify windows registy
Use compatibility mode
Modify the amd drivers and install it unsigned
Thank you for your time!!
EDIT to add a CrystalDiskMark benchmark
