If you open the GpuT2 file location [.....Program Files (x86)/Asus/GPU TweakII ], look for "InitData_Card1.ini". Open/Edit it with your favorite text editor. The very first section Titled "[VGACardInfo]" contains your card, if this is different than what you actually have, then ya you will have issues.
In the same folder is 3 other files with similar name ending Card1.ini to Card4.ini, i am thinking that if you installed your card in a different slot you might have one of these other files as the active settings file, I dont know for sure. (I find GpuT2 clumsily programmed to begin with, so it wouldnt surprise me to see this. )
I dont recommend this but, I renamed the unused InitCard2 - 4.ini files. I did this while I was looking for useless files. I dont know why ASUS includes ATIWinflash and files, ASUS doesnt even use Liveupdate, AFAIK its only in there as a marketing feature. Personally, I would never use auto-update for anything besides Windows Update.
Here is an example of mine:
[VGACardInfo]
DeviceID=0x679A
SSID=0x47E
ModelName=R9280-DC2 TOP
NV_BIOSString=NULL
AMD_OEMString=113-AD65700-100
BIOSDate=02/18/14 04:29
You can confirm some of these with a program like Speccy or other source you can get detailed System Information.
SpeedFan controls fans and temps, once you learn how to configure it properly. :cool:
