I have a Radeon HD 5770 and every time i try and update the drivers from the ones it came with i get severe screen tearing and it was cause the computer to auto restart as well..im not to sure what the problem is i have uninstalled the drivers before installing and i have also tried a new monitor as i heard it might have been that...
try uninstalling them from safemode.
incase you dont know how to get into safemode.
hit F8 a lot of times while booting. select safemode or safemode with networking from the selection screen.
safemode is just windows without any drivers or programs started.
i have tried uninstalling and reinstalling using the driver sweeper..the driver seem to have worked..went to look at the new CCC that i can use and notice that my card is completely clocked down to lowest setting..i try to turn up and the problem reappears.. anyone have an idea?
I can turn the clocks up but whenever i check the *enable AMD overdrive* is when the problem appears
not sure if turning the clocks up without the box checked does anything as i seem to be newb
you are welcome--unfortunately it looks like ati/amd cards dont get the manufacturer picked up by gpuz--nvidia cards tell you if its asus, gigabyte etc who made the card--it may be a powercolour but cant guarantee it
not sure what else you can try if afterburner and ccc wont let you overclock--pretty sure its a software problem but other than a clean install of windows or a second hard drive with a clean install or try the card in another pc i cant think of anything else
i was able to clock up the speed a bit from the default setting with no problems so far...but although it says its clocked up when i test is Kombuster or the sensor in GPU it says its clocked at below the default
Current clock set at-910
Default clock -850
Sensor and kombuster read at -400
