Your best cores are actually probably the ones crashing, they are already running at lower voltage than the rest, a negative curve lowers their voltage even more. Usually you have some a priori knowledge about the data which can motivate ballpark / back-of-the envelope type guesses for reasonable parameter values. When I enable PBO2 @ +200MHz setting I'm required to use a Positive/Negative Curve Optimizer offset of 0 (zero) to retail stability. This, combined with Precision Boost Overdrive 2 means that you’re pushing less heat, allowing the CPU to boost clock speeds. 1 but then I had kernel not found or corrupted bsod. Each step is an offset of 3-5mV, with negative being an undervolt and positive being an overvolt. I also tried limiting Power at 88W, that gave me tremendous thermal improvements (65c full load on all cores) with relatively low performance (300Mhz) loss. ini) to get a grasp of what settings you can change.
