* User is running a demanding application (e.g. game).
* CPU clock speed increases (turbo boost), as long as the CPU isn't hitting: 1) Tj_MAX (max temp before thermal throttling kicks in); 2) the power and current limits specified by the motherboard (in this case, effectively disabled by the out of spec settings).
* Weaker chips will require more power to hit or maintain a given turbo clock speed: with the power and current limits disabled, the CPU will attempt to draw out of spec power & current, causing issues for the on die fully-integrated voltage regulator (noting that there's also performance/quality variance for the FIVR), resulting in the user experiencing instability.
