I have got it to OC from 1.8 to 2.1 but I have not messed with the voltages at all and I have no clue what to do when it comes to the memory. How can I OC my system even further on stock cooling without harming my CPU? My second question is that should I upgrade my graphics card to something else? Reason being that I pre-ordered Battlefield: Bad Company 2 and I wish to play it on this computer. I know my computer is outdated but I do not have the money for a new build and I have a hard time parting with this build since it is my very first build.
