I spoke to one of the most experienced South African Overclockers, SETH, I attended one of our south african overclocking league finals and got some tips from our top guys. They basically told me don't push passed 1.4v if you are beginning. And don't over do anything, after spending time reading up more on forums and getting to know the voltages and what they can do a beginner shouldn't push to hard. Patience, time and knowledge is what makes a successful overclocker, Know your components! Im hoping to attend more of these events and start getting involved in our leagues, South Africa's overclocking community isn't big but it's growing steadily and I hope to introduce a few of my friends to our community.
