Disable boost and reduces CPU temp in games
” I’ve talked about disabling boosting in other threads via adjusting the max state to 99%. The flaw with this method is capping the CPU at only 1.7GHz. To maintain stock 2.9/3.0GHz clock with boosting disabled, use this method below instead of 99% max power state.
Using Registry Editor, go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\be337238-0d82-4146-a960-4f3749d470c7 and select Attributes. Modify the value of “Attributes” from 1 to 2. Data should read “0x00000002 (2)”. This will uncover a hidden power option.
After that, go back in the Power Plan Options and a new tab “Processor Performance Boost Mode” will appear. Set it to Disable and click Apply. Also, make sure your max processor state is at 100%. The CPU will now run on the stock frequency.
For a general idea about the performance compared to 99% max state, average FPS went up to about 5-15 with the temperatures still maxing out at the same 75 degree Celsius! The FPS loss from 99% disabled has been recovered while maintaining the benefit! Tiering your games at 1.7GHz, 3.0GHz, and full boosting will allow greater flexible for performance and temperature. ”
Simpler Method to Disable Boost #
Run cmd as administrator:
powercfg -attributes sub_processor perfboostmode -attrib_hide
powercfg -attributes sub_processor perfboostmode +attrib_hide
Configure it in your preferred power plan
Control Panel/Power Options/Change Plan Settings/Change advanced power settings/Processor power management/Processor performance boost mode
While Disabled (Default: Aggressive) your thermals will improve drastically with minimal (CPU intensive games) or zero performance lost. If you don’t want to completely disable it use Efficient Aggressive.
