AMD graphics crashing. Please help!

[halfbreed]

I have an Gigabyte R9 270x 4gb card and have had it for about 8 months with no issues. 

A month ago I started playing around with overclocking and found what seemed to be a stable clock speed.

In the last week I have been having issues with one of my screens glitching out and going white. Sometimes my game crashes, other times it keeps going.

This tend to happened when I am doing multiple things. 

I receive a driver crash notification but my drivers are all up to date. 

What could be wrong/what can I do?

Check the fan to see if it is working properly.  Check the video card temps at idle and under load and while gaming and such.  Point is check to see if it is overheating.  
 

Oh and of course you should remove all drivers and reinstall them again and see if that helps in any way.  With AMD do they have beta drivers?  If that is what you are using then roll back to regular drivers.

Lower your overclock.

Overclock doesn't seem stable, try to turn it down a bit. The R9 270(x) seems to not fare very well to memory overclocks in some games.

Just focus on the core clock.

Memory clocking will give you a gain, but it's not much compared to what core clocking will give you...

 

The gains with memory clocking on other cards may give better performance gains, but the 270x, upping the memory clock doesn't do much.

Fans and temps are stable. Even overclocked the card never broke 70 C. 

I cranked down the overclock yesterday and it seemed okay until the issue happened an hour ago.

I have set it to default setting to see if that fixes the issue and maybe go back and overclock later.
