Help overclocking Sapphire HD7970 Vapor-x 3GB crossfire

Kinda of a newbie in overclocking.

 

My current setup is 

 

i7-3770K

16GB Corsair Ram

Sapphire HD7970 Vapor-x 3GB Crossfire

Seasonic 860w platinum

 

I have been experimenting with changing the GPU clock to 1185 MHz and the Memory Clock to 1590 MHz.

It would run fine initially however after around maybe 10mins of play, my computer will hang when I am running the Witcher 2 EE at full spec 1080p.

 

Any help will be much appreciated. ^^

Download Sapphire TriXX or MSI afterburner.

 

Turn up the fan speed manually to say 70%

Adjust the clock speed of the GPU up in 15Mhz increments until it crashes. Reboot adjust the voltage up by 20mv and retest. Wash rinse repeat until you reach the level you are satisfied for long term gaming

Then use the same methodology minus the voltage increase.
