I got an A10 7850k Black edition processor and I'm having this isue with the Igpu, it's only working at 351mhz. When i load up a game, it is still locked at 351mhz.
On Catalyst Control Center, opened up GPU OverDrive, and it allows me to check to activate the overdrive and change settings, however when i check, i can't change the values and if i Apply it auto uncheck. Btw it always show a 0% power.
When i open a heavy game, it shows 100% use at 351mhz. Some rare ocasions i see get a sneak to 720mhz but it last for < 2 sec and the game still lags and sometimes i got small freezes.
Full rig is:
Asus A58M-A (FM2+)
A10 7850k Black Edition
2x 4gb TeamGroup Vulcan Gold DDr3 2133mhz c10
Water Cooling system by CoolerMaster Seidon 120v
PSU CoolerMaster 500w Elite V2
I havn't got any dGpu.
Any help would be apreciated.
Try to install Catalyst Omega (14.xx) or 15.6 Beta.
I had this same issue and it's solved installing an older driver.
