‘0’ indicates to park as many CPU cores as possible. To adjust it so that only 25% of available cores remain active at all times, allowing 75% of available cores to be parked, you’d run: powercfg -setacvalueindex scheme_current sub_processor 0cc5b647-c1df-4637-891a-dec35c318583 25 To mandate 50% of available cores always remain unparked, run: powercfg -setacvalueindex scheme_current sub_processor 0cc5b647-c1df-4637-891a-dec35c318583 50 It is unlikely you will ever need this, but… powercfg /qh > powerconfig.txt You can adjust specific ones by using their GUID, or switching to them prior to running these commands.įirst, backup ALL your Power Settings by creating a dump of everything to a TXT file. Note that these commands adjust the currently active power profile. You must run this utility with elevated rights, so be sure to open an elevated console window by right-clicking ‘cmd.exe’ and selecting ‘Run as Administrator’. You can also change these settings via Window’s Powercfg.exe.

However, generally, Windows is too aggressive in its core parking, resulting in excess latency during bursting CPU loads (the most common type). There are many factors that will determine precisely how efficacious it will be for any given system. EfficacyĮmpirical evidence shows that disabling core parking can make a real difference in system performance. Process Lasso has a similar feature with its IdleSaver. ParkControl has Dynamic Boost to allow you to set active and idle power plans. For instance, with Process Lasso, you can automatically enter ‘Bitsum Highest Performance’ will you start a game, then go back to ‘Balanced’ when you exit. ParkControl (and Process Lasso) not only let one more easily configure CPU core parking and frequency scaling, but also allow for dynamic entrance into a higher performance power plan. The new ‘Ultra Performance’ power plan copies what Bitsum did with our own ‘Bitsum Highest Performance’ power plan and finally disables core parking entirely.

Even the default ‘High Performance’ power plan is not immune. Intel moved core parking control onto the chip in the Skylake generation, and AMD followed, but still the parameters of the Windows power plans are set to aggressively park CPU cores. The aggressive core parking of Windows led to a great deal of inefficiency during bursting CPU loads. Initially, core parking was controlled entirely by the operating system. Unfortunately, this power saving comes at a price: Latency when CPUs need unparked to execute code. It dynamically disables CPU cores in an effort to conserve power when idle. CPU Parking is a low-power sleep state (C6) supported by most modern processors and operating systems.
