5770 sudden decrease in performance

[Willus Killus]

Been running a 5770 for around a year and a half now, and as of yesterday I experienced a sudden drop in performance.

Was running Medal of Honor at pretty high graphics without any frame rate issues, next day it is only just playable on low settings, also experienced terrible performance with Portal 2.

Also noticing some artifacts such as the one this fellow kindly demonstrates (middle of picture, glowing character).

I have done a full re-install of windows and the problem still exists.

Was wondering if anyone had experienced anything similar or if anyone might have any clues? I suspect the card is just worn or has damaged itself somehow.

Check it's load temps if very high

unscrew the cooler clean off the paste and reseat with thermal paste and keep an eye on temps you can use hw monitor to see what max temp it reaches shouldn't really be going much over 70c (not that 70c is unsafe i think more than likely is safe at 85c even) if the fan and coolers working properly.

Would also try uninstalling all ati software drivers etc associated with the card then getting driver sweeper Version 3.2.0.

So uninstall driver just use express uninstall all ati software then reboot then run driver sweeper clean out ati reboot then reinstall catalyst 11.8

The card idles at 34°C and I've never seen my temps go over 60°C so I don't think its a heat issue, I usually pay attention to that sort of thing too, since it was the death of my last card

The way it worked fine one day, and then when I booted up the PC the next day, the issues began makes me suspect more than just overheating.

I have also already tried a full re-install of Windows and the drivers.

recently had a 4780 do the same, now have to play cod4 all low to get 60 fps.

I thought my PCI-E speed was supposed to by x16, however it seems to be displaying as x1?

Also shows up the same in GPU-Z

have you got 2 pci-e slots ? can try in the other slot ?

Nope, just the one.

only way to be sure then is trying it in another board

Hey im not sure if this will work however go into your bios and you can alter your pci speed. i had a problem with that once on a reaaaly old system. but it could have been caused by a bad file or something? cant hurt to check you should be able to find it in there and you should be able to change it with ease. if thats the problem

Solved the problem

Took card out, booted system, shut down system, put card back in.

Seems to have reset something so the card is now using x16. Could just not have been seated properly I suppose.

anyways, thanks for the help gents.
