I am very new to overclocking and a bit worried as im on a tight budget. I have an AMD X2 7750+ (Black Edition) as you know it comes set at 2.70Ghz and just wanted a slight overclock using stock cooling (I have also added 2x 80mm case fans). I knoticed you can set the speed easily in the bios if I simply increase the processor speed to 2.8 or 2.9Ghz do I need to change anything else such as voltage or anything and will simply just changing this make a very slight difference without heat problems? (im not after a massive improvement just seemed I might aswell do something for free if it is avalible) Thanks People!
