I have no clue whatsoever how to use this tool

, but I would like to know if there is anything I need to change. I intend to OC my system this week,and thought that "perhaps" doing some adjustment to memory should maybe be done aswell.
In my BIOS I can set the voltage up to 2.8 btw, and the actual speed is 200Mhz (the modules support 400Mhz), other than that it is 3-3-3-8. On another forum, one guy said I do not need to "touch" the memory if I intend to clock in small values, but I don't know how far I can OC the cpu.. Maybe later today I'll get a better hs/fan for the system instead of the stock bs/crap that is on right now. I managed to get from a friend a 120mm fan for cpu's since he went into the "water business".
Thankful for any replies given.
