Ratio Memory Clock / GPU Clock on 7970 DC2

Hi everyone,
As I'm new to the world of overclocking, I'd like to have some advices. Are there "good" values to choose concerning GPU Clock and Memory Clock?
The default values for my card are 5500 MHz / 925 MHz , which gives a ratio of ~5.95. Should I keep approximately this value when I overclock my card? I'v set three other custom profiles, 5700 / 965 , 5928 / 1005 and 6088 / 1045, do you think these are optimal ? 🙂

Thanks in advance for your advices.
PS: sorry for my not very good English 🙂

That not the calculation in real life. Not all card come to the same. You need find the sweet voltage spot for every card. I can oc my card t 1125MHz at 1.13V @5600MHz does not meant your card can do it too. Template just a guide line but not all.
Change is the law of life. And those who look only to the past or present are certain to miss the future.

Ok then it seems that there isn't good values, even for a single model, as I thought. Thank you booth for your answers. I had a quick look at the guide and it seems exactly what I was looking for 🙂
