I'm still having problems with my 4850 blue screening frequently thanks to atikmdag.sys.
Currently have:
Visiontek 4850
Asus P5Q Deluxe
4x hdd
Silverstone ST50EF+
4x1gb PC6400
E4300
Vista ultimate x64
And it crashes randomly, usually with the "atikmdag.sys has crashed and successfully recovered" several times, then it blue screens with the problem being atikmdag.sys. Usually when I'm not doing anything gpu intensive; this almost never happens while playing games, usually only when surfing the internet. Add to that, several people I've talked to say that it's typical of ati drivers to be terrible (which I agree with) and that they crash frequently.
Which is completely unacceptable. My old 7900gtx had absolutely no problems with stability. Sure, the drivers would crash, but they'd always recover successfully and I could just carry on with doing what I do.
Things I've tried:
Catalyst 8.6
Catalyst hotfix
Catalyst 8.7
Catalyst 8.8 beta
Catalyst 8.8
Default windows driver
Un-overclocking
Running with 2 sticks of ram
Different pci-e slots
Driver cleaner, ccleaner, driversweeper every time I install a different driver
putting more fans by it
trying a different power supply (OCZ StealthXStream 500w)
Multiple re-installs of vista
And none of them make it any better.
Things that I'm not going to do:
downgrade to xp
Things that I'm considering doing at this point:
buying an 8800gt 512, 9600gt, or 9800gtx+ and just taking a large loss on the 4850.
