To Overclock or Not. Well that's up to you but theres a ton of factors "HEAT" being number one and you dont want your voltage to fry your Shioloah eh. Here is a link to the site I got the info to actualy use the Voltage mod itself on this board.

I've learned a ton from cooling, to a good Power supply, to chipset cooling, video cooling and most importantly CPU Cooling as well as Case Cooling.
It's taken alot of time and patience to read and learn from other ppl as well as onhand experience. Again there realy is no need to overclock these days, But if your like me and want to get a 1600 from his 1.3 then woohoo for you as You can maybe get some useful stuff from here in a few minutes instead of researching for several hours as well as testing. :)
