ThrottleStop

Reads and adjusts Intel CPU throttling behavior, voltage offsets, and turbo power limits on Windows laptops and desktops

It takes care to curate a safe software space. Help us do more.

&

+
Throttle Type Monitoring
Reports in real time whether the CPU is being slowed by thermal, power limit, or VRM-related throttling on a per-thread basis.
+
Clock Modulation Control
Displays and lets users disable OEM-configured clock and chipset clock modulation that silently reduces CPU speed on many laptops.
+
Set Multiplier
Manually fixes the CPU core multiplier so the processor runs at a chosen speed instead of relying on automatic Turbo Boost or SpeedStep transitions.
+
FIVR Voltage Tuning
Opens a dedicated window to adjust core, cache, and other voltage planes through the Fully Integrated Voltage Regulator for undervolting or stability tuning.
+
Turbo Power Limit Editor
Exposes PL1, PL2, and related MSR and MMIO power-limit registers so users can raise or lower the wattage a processor is allowed to sustain.
+
Disable and Lock Options
Locks selected power-limit or turbo registers after they are set, preventing OEM firmware or background utilities from silently reverting the change.
+
Speed Shift Configuration
Adjusts Intel Speed Shift minimum, maximum, and Energy Performance Preference values to influence how aggressively the CPU ramps clock speed.
+
PROCHOT Offset Adjustment
Raises the temperature at which thermal throttling engages, letting supported processors keep boosting closer to their thermal ceiling.
+
Per-Profile Settings
Stores up to several independent configuration profiles, each with its own power limits, voltage offsets, and Speed Shift values, switchable with keyboard shortcuts.

Notes

Recommendations before use:

  • Monitor power draw at the wall outlet when raising turbo power limits, since exceeding a laptop’s power adapter rating can damage the adapter or the system
  • Test stability with the built-in TS Bench after any voltage offset change before trusting the profile for daily use
  • Check whether the laptop’s firmware has disabled voltage control (a known side effect of Plundervolt-related BIOS updates) before assuming a hardware fault
  • Ensure that voltage offsets are stable before configuring autostart
  • Configure autostart through Windows Task Scheduler with administrator rights rather than the standard startup folder, since ThrottleStop needs elevation to function at login
