Game crashes after Overclocking/ Display Driver stopped responding

post #1 of 18
Thread Starter 
Hey guys i just overclocked my VTX3D 7950 from 880/1250Mhz to 1050/1550Mhz. If i run unigine heaven benchmark it crashes and diplays me "Display driver has stopped responding and has recovered successfully, Display driver AMD driver stopped responding and has recovered successfully."
Or it shows an image with stripes (sorry for bad explanation but I couldn't find a reference picture on the internet) and i have to force shutdown the computer.
I know there is more possible with this graphic card. But how can i unlock this potential?
My computer runs Windows 7 64bit.

When over clocking GPUs I usually look for the max over clock on mem and core separately.

Put the GPU clocks back to stock.
Then Up just the Core clocks. When unstable up the volts a little. Eventually you will find your max Core overclock.

Put that back to stock and then do same for mem.

n my experience when you combine to two Max clocks together it will be unstable. If that s the case lower the mem. It produce less of a positive benefit.

sounds logically and thank you for the tip but how do i increase the voltage?

I think i need a new cooling solution, I play with stock core and mem settings and the h7950 is already at 67°C
