Hi all !

I'm have mainboard MSI B75MA-P45 (MS-7798 socket 1155). I'm connect SSD Samsung Pro 256GB and run SATA at IDE mode. I need enable AHCI mode to max optimal performance of SSD. But i'm login to BIOS setup and cannot find AHCI mode. SATA connection just display IDE, RAID mode and disable SATA ??? AHCI mode do not display ? I'm know MSI B75MA-P45 has support AHCI mode but i cannot find this ? BIOS firmware of me this is latest version. Please help me ! Thanks all ! Sorry because English of me is bad !

Gear of me: MSI B75MA-P45 | Intel Core i3-3210 | 2x4GB RAM bus 1333hz | Samsung Pro 256GB...

Settings>Advanced>Integrated Peripherals>SATA Mode there
However read this note:
"You cannot switch between AHCI and IDE if you already have your operating system installed. If you have installed your OS using AHCI and you clear your BIOS/reset to default settings, you will need to change this function back to AHCI to ensure proper functionality."

So if you have installed Windows in IDE mode, BIOS may make it impossible to switch to AHCI mode.
