There is a reason why intel advertises a regular and "Boost" clock speeds. Boost clock is not sustainable without heavy duty cooling and the CPU will throttle down once it's heated up.
- atvrager 5y agoThrottling's normal and expected. OP indicates "shuts everything down" though -- which sounds more like the CPU turned off to prevent damage. That shouldn't happen if the cooling is working properly.
- saltcured 5y agoI think the miscommunication is around "shuts everything down". Some of us are reading that as an emergency power-off event far beyond normal thermal throttling, which is just a reduction in clock speeds within the typical variable clock range of the power management system. I don't know if it still holds, but some older systems also had a third category of throttling in between the normal speed range and an emergency power off. They would stutter badly as if they were applying some duty cycle and alternating between a suspended state and a slowly clocked state. This would show up as really frustrating IO buffering and UI latency, similar to how a machine might behave if it were stuck in a virtual-memory swapping storm and processes would freeze/unfreeze sporadically.
