From the driver download page I see this note. I have a couple of questions:
1. Are the 14.4 drivers OK now and,
2. What is the seperate AHCI driver component download mentioned below? If it's not in the regular package would it affect my system somehow?
AMD has received feedback that some users are unable to install the Catalyst 14.4 driver on some motherboards with AMD chipsets. We have investigated the issue and have determined that it was caused by the AHCI driver component that was included with the driver package.
We have therefore removed the AHCI driver component from the driver package and will be providing it as a separate download.
If you were affected by this issue, we recommend you download and install this updated version of the driver.
