Hi,
So I have a HIS Radeon 7870 graphics card and I have started to due some overclocking. I was using iTurbo for a while but didn't like it to much and decided to get Afterburner which seemed to work fine. But here is my problem. Whenever I change my Core voltage to 1300 mV, when I save it and then load another profile and then go back to the profile set to 1300 mV, it reverts back to 1219 mV?!! Another thing is that when I set the core clock to 1175 MHz, save it, load a new profile and then reload the profile at 1175 MHz, it sets itself to 1200 MHz! I didn't set it that way so why is it doing that?! Also I checked the boxes saying unlock voltage control and unlock voltage monitoring. So any help would be great because I don't know what's wrong.

P.S. I did though yesterday have it set to 1200 MHz and then it crashed and so I am trying to lower i but it keeps going back to the 1200 MHz.

Probably your voltage if it caused a crash. You should up the clock in small steps at a time and see what your unique card is capable of. For example, up the memory clock by 20, benchmark, if all is good (temp, no dead pixels) there you can higher it by another 20...

I did hit apply and then save. Actually though, believe it or not it started to work for some reason. What I did was instead of just typing in the numbers and hitting enter, I used the slider and for some strange reason it worked. But i got a quick question, my computer crashed after I moved the slider to 1175 MHz, is my core clock too high or is my core voltage too high at 1300 mV?

For example, up the memory clock by 20, benchmark, if all is good (temp, no dead pixels) there you can higher it by another 20. You can then higher the voltage for better results. Be wary though, an overclocked card is a less durable one!
