Use drivers from AMD's site, no modded one you don't need a modded one.

 

thanks for your respond

i tried all of amd drivers nothing changes

it recognises that the clock of my card are 900 and 1000 but sets it to default settings 150 and 300

please hellpp me

 

no one please ..

 

Try running MSI Afterburner and set the clock with it, see if it wakes up your memory.
