Today I used the AMD CCC overdrive utility and found my processor clocked at 4 GHz from the standard 3.6 GHz...very unstable. I reset the BIOS to default and lost my SATA controller setting of AHCI. When I set the BIOS to AHCI windows crashes with "can't find device error".

The registry setting for msahci is still at the value zero.

The system was rock solid with a Samsung 840 EVO. Samsung Magician indicates it is unable to detect SATA interface details.

First of all - welcome to BC !

 

The Gigabyte manual should be able to provide the info to solve this problem. If you don't have a copy you can download one (pdf) from here :-

I can usually fix BIOS problems, but I can't do it from memory, and I can't cycle through my own BIOS and use the web at the same time !

Hi Chris,

 

After reading the manual I decided to set SATA ports 4/5 to "SATA type" from IDE, in addition to setting SATA ports 0/1/2/3 to AHCI

 

The system now boots fine and Samsung Magician indicates AHCI is enabled.

 

TY

Glad it's sorted !

 

As NickAu has been known to say on occasion "Reading manuals will NOT give you leprosy"

 

I know - I normally only read them when I get into trouble as well.
