I've a 560 Ti SO 950 and it's getting crashes with any of the drivers after the 270.61 release.
With the 270's it's rock solid stable, but with the later releases it's been getting TDR crashes (which seem to be a common bug for many users), or Aero crashes and then the card starts heating up with the fans going at max speed. The overheating aero crash is what worries me particularly because I daren't try the new drivers without being at the PC in case it happens and fries the card.
The crashes tend to happen when the PC isn't doing anything, maybe some web browsing or watching online TV.
So far I'm just using the 270's for safety, but am finding the stability/heating issue a worry. I'm going to get in touch with Gigabyte support about it and see if any one on the Nvidia forums can help.
I really don't want to have to under clock the card as I paid for the OC version and expect it do do what it says on the tin. My rig is well ventillated and other temperatures are fine.
Any help or comments by anyone else who has come across this problem would be appreciated...
Cheers - Andy
