Amd Chipset Driver Auto Detect
AMD RS780 SB700 benchmarks, AMD RS780 SB700 performance data from OpenBenchmarking.org and the Phoronix Test Suite. Well in my case, my mechanical hdd noticed a more than 30MB/s increase in write speeds just like in the above article where the H55 chipset beat the AMD solution on sata write speeds. With my ssd, the read speeds increased, most significantly starting with the 16.0 test and throughout the rest of the test.
Amd Chipset Drivers Necessary
A web search led to the solution and now I have the AMD AHCI driver working with the AMD SB700 chipset on Windows 8.1 x64.
The solution was provided by linhtinh on the AMD forum and involves correcting an error in the amd_sata.inf file. Run the driver's installer to extract but don't install. Navigate to the proper AMD.Sata.INF file and open with Notepad. The line below should not begin with a semi-colon.
;HKR, 'ParametersDevice','AmdSataPMDisabled',%REG_DWORD%, 0xFF
Delete the semi-colon, save the modified INF file and install the unsigned driver from Device Manager.
For how to install an unsigned driver, see here http://www.howtogeek.com/167723/how-to-disable-driver-signature-verification-on-64-bit-windows-8.1-so-that-you-can-install-unsigned-drivers/
The modified driver must be installed from Device Manager in the following manner. Right click, update driver software, browse my computer for driver software, let me pick from a list of device drivers on my computer then browse to the correct folder and install. Reboot and done.
