I have a radeon HD 7850. I've been trying to overclock it with MSI afterburner, but sometimes the overclock applies and other times the overclock refuses to apply and is stuck at default clock (860 Mhz) no matter what I do, this time it's been doing it for days now. I'm not even overclocking that much, only a little bit and still within the limits. I've tried reinstalling msi afterburner, didnt help. I uninstalled video drivers and installed the latest crimson driver, didnt help and still stuck at default clock. I tried using radeon settings overdrive to do it, still doesnt apply. wtf is going on.

Like I said sometimes the overclock works but other times it just doesnt work for no apparent reason.

I'm using windows 10 pro 64 bit, but this problem happend with windows 7 too.

Uninstall AMD driver with DDU. with the reboot option. also uninstall MSI AB and delete old files folder on the drive where it was installed and install 4.2.0 version , try 16.8.3/16.8.2/16.7.3/16.7.2
