Prime95 gave me similar results to IBT, so saying the whole guide is BS is rash to say the least, Gr1mR34p3r. Got an easy 4.6GHz@1.355v with temps in the 70s at load with my 2600K and Z68 thanks to this guide and running beyond stable. People are pushing their voltages and temps higher, but the guidelines for keeping a cool and quiet PC [and a non-fried CPU] are much appreciated!
