QUOTE how can i tell if it worked. the driver properties still reads 18.104.22.168?
AMD have simply been a little lazy in updating the internal dates and version numbers of their installation files as determined by the INF file (amdk8.inf) that is extracted when the driver package is unzipped.. (although you won't see that since you used the .exe version rather than the zip version)
You have to go to windows and examine the driver dates that are actually being used after you do the install to determine if the installation worked.
When you extract the files from the latest (22.214.171.124) downloaded zip file, you'll see that the actual driver amdk8.sys from: Version 18 is dated 8/11/2004 and is 39Kbytes.
The previous version was Version 14 and is dated 5/8/2004 and is 35kByte......
When you install the newest version 18 driver, yes they show the same version in the Device manager, but if you look in Windows you'll see the new driver is in place by examining the date of AmdK8.sys.
New driver - 126.96.36.199 C:\WINDOWS\system32\drivers\AmdK8.sys = 39KB = 8/11/2004
As I said, don't worry what the Device Manager says about the versions being used in this case......it simply uses the amdK8.inf contents that is used to load the driver. If you look inside that file (with notepad) you can easily see that it hasn't been changed to reflect the new driver dates, even though the driver itself is new.
Personally I edited the amdk8.inf file with notepad before I loaded to reflect the correct dates and version, so then when it is loaded I will see the correct version in the Device Manager...
