this has been done already Cry

core now running at 850 MHz with 490 KH.. thats what miztaziggy stated.
Any explanation?

Don't worry about overclocking past its limit. You can't damage the card unless you over volt it.

Just try it at 1000 / 1600 see what you get. I think the 7970 will go higher than the R9 280x that I have anyway. The things I have read suggest about 1150 clock and 1900mhz memory for a 7970.

Apparently the best settings will be at a ratio of clock to memory of about 0.6.

If yours doesnt work at 1000/1600, all that will happen is your screen will go blank and either computer will restart, or, it will go back to desktop and you will get an AMD Driver has stopped responding and has been restarted message. If that's the case, try 960 clock and 1550 memory.

Mine works fine at 1000/1600 but if I go to 1020 / 1650 it restarts my PC after a few minutes.
