Just keep an eye out for a fix from Microsoft. If the machine stays stable and you have no other problems, you’re probably fine to use it. Then disable BD PROCHOT and run the same check after giving the system time to warm up.

So before you disable BD PROCHOT, if you’re concerned about the impact, take a moment to familiarize yourself with how hot your Surface Book or Surface Pro 6 feels to the touch now.

If you run into problems, you can use the utility again to restore default functionality.ĭevices like the Surface Book and Surface Pro 6 are thin, which means any significant source of inappropriate heat is likely to migrate to the surface (no pun intended) of the device. See if you notice any inappropriate behavior or hot spot formation on the device. Don’t disable BD PROCHOT and then run the ugliest thermal workload you can find - turn the flag off and let the system sit at idle or run a YouTube video. Users who need to use ThrottleStop to restore normal functionality can probably attempt doing so. There are non-Surface users who have reported BD PROCHOT issues as well over the years, so this isn’t a Microsoft-specific instruction or capability, though the issue does seem to be hitting Surface in particular right now. Customers report these problems on products that show no signs of any overheat, and some customers who have used the ThrottleStop utility to turn the BD PROCHOT function off have gone on to use their products for a year or more without any problems. But this does not seem to be an explanation for what’s going on with Surface devices. The flag can be thrown by a different component that isn’t the CPU, which means (in theory), you’re overriding a component that’s trying to preserve its own functionality by telling the CPU to slow down.

Some modern systems measure skin temperature and use it as part of determining their operating frequencies, for example.īecause BD PROCHOT is bidirectional, there’s a potential risk here. It was introduced at a time when individual components paid less attention to their own thermal conditions and performed less clock throttling overall, though that intelligence has been baked into mobile hardware at various times and in various ways. Microsoft makes no warranty, implied or otherwise, about the performance or reliability of these products.It is not clear exactly which components can use the BD PROCHOT function. The third-party products that this article discusses are manufactured by companies that are independent of Microsoft. And Turbo Boost drives the processor above 100% of its nominal speed, and allows the processor to exceed 100% capacity. With the redesigned Task Manager, the first processor is shown to be running at 50% capacity, whereas the second processor is shown to be running at 100% capacity.

Before this change, under the time-based performance counters (used in Windows 7 Task Manager), both processors appear to be doing the same amount of work: 100% of their capacity.

A processor that's running 100% of the time and clocked down to 50% frequency performs only half the work of a processor that's running 100% of the time at 100% frequency. This change was intended to provide a more accurate representation of how much work the system is handling. The utility performance counters take into account the processor performance state and Turbo Boost-based enhancements to measure and normalize the work that's being done by the CPU. The time-based performance counters measure the percentage of time that the processor is busy, whereas the utility performance counters measure how much work the processor actually performs. The difference between the two counter types concerns how they measure the actual work that the processor performs. The values in Task Manager now correspond to the Processor Information% Processor Utility and Processor Information% Privileged Utility performance counters, not to the Processor Information% Processor Time and Processor Information% Privileged Time counters as in Windows 7. This change affects the way that CPU utilization is computed. With this change, CPU utilization may appear to exceed 100% when the system is under a heavy load, especially when capacity is boosted by Intel Turbo Boost. Starting with Windows 8, a change was made to the way that Task Manager and Performance Monitor report CPU utilization.
