if your OC just do it from the bios software can mess things up and it easier once you start to know what your doing.
A member here thought he would post benchmarks based on a "setfsb" overclock then he only tells us a little info then wants people to guess. My point is if he would have said in the beginning that he's using a crap software like (setfsb) most if not all of the member's would have told him what he wanted to know but because he only gave part of the info and left out really important stuff, like i use crap software this is what's causing he's problem. this is one of many reason's i say start in the bios to avoid stupid mistakes like this.
