Hello, I've been trying to get my SATA to run through AHCI and have been failing miserably. I'm not even quite sure what it means to have it on AHCI, but from what I understand it is faster. Seeing as I've spent quite a bit of money on all new computer parts for my first build, I would like for it to run top notch.
I've already tried changing to AHCI mode in the BIOS and the computer fails to start when I do this.
I then tried installing the drivers for AHCI from the internet which failed as well, prompting a message that claimed I did not meet the system requirements. I read the system requirements and I would have to think that the only one that I wouldn't likely meet would may be the last requirement which states... "The intel chipset software installation utility must be installed prior to installing Intel (R) Rapid Storage Technology"
I've now accepted that I don't really know what I am doing and am now seeking help.
Here's my set up
SSD: Plextor M3 Series PX-256M3 2.5" 256GB SATA III Internal Solid State Drive (SSD)
Mobo: ASUS P8H77-V LE LGA 1155 Intel H77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard
The bios has to be set to AHCI prior to installing the OS. Making changes to AHCI after installing the OS will cause the problem you were having. During windows installation, it examines your hardware and bios settings and install drivers accordingly. Since you didn't initially have AHCI turned on in the bios, the drivers didn't get installed.
Good job on researching your problem and figuring it out yourself.
