Title: R7 260X - Stuck on 150Mhz unless 2 monitors are plugged in? Post by: adaseb on June 26, 2014, 02:59:31 AM With the X11/X13 algo, I noticed my R7 260X is stuck at 150Mhz memory clock speed without any monitors being plugged in. If I plug in 2 monitors to both ports then it runs perfectly.
It doesn't do this on Scrypt or Scrypt-N When I unplug the monitors, it downclocks the memory clock. It does this in Windows and Linux Title: Re: R7 260X - Stuck on 150Mhz unless 2 monitors are plugged in?

It does this in Windows and Linux im not wuite sure why this is happening to you , but the easyest fix would be 2 "dummyplugs" to simulate connected monitors. you can browse instructions easily here on forum. i have some 270x, but dont have any problems what so ever, are you sure you are on latest catalyst ? cheers Title: Re: R7 260X - Stuck on 150Mhz unless 2 monitors are plugged in?

It does this in Windows and Linux I suspect its the driver problem. Title: Re: R7 260X - Stuck on 150Mhz unless 2 monitors are plugged in?

Any suggestions? Works fine with Scrypy and N-Scrypt |
