Nothing to it really. Download unigine valleyor heaven 4.0(valley is newer). Set settings to extreme hd. Run it while monitoring with precision X or afterburner. The clock speeds shown in the bench programs are not correct. So check the precisionXgraphs afterrunning the benchmark. If the max clockspeed shown on the precision X graph is 1150mhz for example then raise the slider+100 so you end up on 1250mh. Also put the power target slider to max andtemperature slider to max, this will make sure your card will not be throttling when using more power then normal or when it gets hotter then normal. Also a good idea might be to put your fan manually on 70-100% .Run the benchmark again and if you didn't crash up the slider in 10mhz increments. 13mhz actually is best cause the card can only clock multiples of 13mhz so be not surprised if you click +100 and your card only goes up 91mhz. If your card crashes during one of the run you will get a black screen. Just control alt delete and shut down or restart pc and everythingwill be fine again. When you have reached maxstable core try the memory clock.start in 100mhz increments and once you crash or have a lower score, lower it by 50 or 25 increments. Be sure to write down stable values on a piece of paper. Then as a last tip in precision X you can press voltage and then raise the slider up, this will up the voltage 12mV and may help with a better clock, but it didn't do anything for me.
Edit: the way many GPUs work is that the higher you clock the coreclock, the lower the memory oc will be and vice versa if you do not overclock your memory you will probably get a higher core clock. You have to find an optimal equilibrium for your card cause each card is different. Generally the core clock is most important for gaming performance. But in the valley benchmark memory clock can add quite a bit of points. Also try to walk around a bit in the valley with free camera and play with weather and time of day and such. The valley is a beautiful place
