**** Moved to Asus AMD Boards ****
Welcome to the forum, I hope that someone can help you with your questions but unfortunately I can not suggest a speed to run your system at as not all components are created equal.. as you state you are a 'n00b to overclocking' perhaps it would be advisable to read the beginners guides on the front of overclockers.com which will give you an indication of the task ahead.. and hopefully we will then be able to assist with any questions you have, however you would need to tell us more about your system such as tempratures and the hsf being used.
