This issue is specifically affecting Intel's K-series line, which are engineered to run up against the CPU's thermal limits. Basically, as long as there is load on the CPU and the CPU is running below 100°C, it keeps cranking up the frequency and voltage until it hits that barrier. I am quite sure that this behavior is what is causing CPU lifespan issues as pumping a theoretically unlimited amount of volts into a CPU can't be healthy. AMD is doing this performance hack on their newest AM5 Ryzen CPUs as well.

- segasaturn 2y ago> Intel® Thermal Velocity Boost (Intel® TVB) is a feature that opportunistically and automatically increases clock frequency above single-core and multi-core Intel® Turbo Boost Technology frequencies based on how much the processor is operating below its maximum temperature and whether turbo power budget is available https://www.intel.com/content/www/us/en/support/articles/000097061/processors.html https://www.intel.com/content/www/us/en/support/articles/000...
- necheffa 2y agoTVB specifically is exclusive to the i9 product line, but K SKUs in the i7 line have also experienced a heightened occurrence of stability issues. So you kind of have to go all in on Turbo boost 3.0 as the issue and then explain why the non-K variants of the i7 and i9 don't seem to have the same frequency of occurrence.

- necheffa 2y agoYou may want to take a look at some of the sleuthing Wendell over on Level1Techs did. He was able to identify a large group of CPUs used in W680 chipset motherboards (i.e. using stock Intel power curves, never seeing a lick of overclocking/overvolting) which exhibited issues. It would seem enthusiast ricing is, at best, an aggravating factor to some other underlying cause.
- ThatMedicIsASpy 2y agoThe large group of W680 are the game servers running 13900 & 14900.
- necheffa 2y agoIs this just an informational statement or were you trying to highlight a perceived shortcoming of what I had said? If the latter, I am afraid I don't see the point you are hinting at and need more clarification.
- mafuy 2y agoYou misunderstood. Some modern CPUs are designed to overclock themselves. The user does not have to do it anymore. It happens automatically.
- necheffa 2y agoIt isn't "overclocking" if you conform to the Intel specification. What you are getting at is Turbo boost, which is not a new thing. We can split hairs over the incremental enhancements to Turbo boost over the years of course.
