Hi truehighroller,

I also think, that IBT is a good stability test, but IBT doesn't test the board voltages like VNB. To find out the right VNB and VTT, you should use Prime95 "In-place large FFTs". With IBT you can check the VCore, instead of using Prime95 "Small FFTs". But imo Prime95 still is the best programm to test the stability of OC.
