Captain G Strings guide to undervolting your Laptop with Throttlestop!
Version 1.201 Of my guide.
****** THIS ONLY WORKS FOR INTEL CPUs. *******
Editing will continue with tips from you guys, grammar mistakes and future ThrottleStop updates. I am not responsible if you misuse this information.
1.1 Added Support 1/15/2022
1.201 Added CinebenchR23 details, Reworded for easier understanding 2/14/2022
INFO: Some Laptops have to be unlocked in the BIOS when your computer starts up and unlocked to enable overclocking. Please google your specific Make/Model to figure out how to do this. Example: GE76 Raider goes to bios on start and hold Right Ctrl, Right Alt, Left Shift + F2 to unlock overclocking.
Note: You can see in the photos that i already applied the decrease in voltage so you would know what it looks like. Your system will probably not have the same voltage decreases as mine because every laptop is different.
The links in the list are pictures to help!
- Download Throttlestop
- Make sure the check boxes on your ThrottleStop main menu matches with the check boxes here
- Click - "FIVR" on the bottom
- Make sure you are in "CORE Voltage" and then Click the unlock adjustable voltage check box
- Make sure you are using the slider that is "OFFSET VOLTAGE" for this. You can ignore the other two entirely. At this point we will need to figure out the maximum, safe voltage reduction your PC can handle. We will be reducing your voltage slowly, by 1 or 2 clicks at a time or -1 or -2Mv. Now you have to figure out your own safe voltage. If you have reduced to much voltage, your PC will crash or become unstable. Just keep (Red Circle) sliding it back to (Green Circle) -.50mv, or -75mv or -100.6mv. Now for me -100.6mv is safe and gives me the best performance/cooling, but your system could be -25, -45. You will have to test your own limits. The lower, the cooler your CPU will go . This is where it gets tricky because you want to decrease small increments to figure out what the limit is on your CPU's voltage. Once your laptop crashes, youve found your voltage. Its completely harmless, just restart your PC and start over. I promise it causes no damage. Its made for this. Do small increments at a time. Deceasing -3 to -5Mv at a time. Each time you make a decrease, click the apply button and test it with cinebench. I know its long, but its worth it.
- Now goto the bottom right and hit "Apply"
- Now Click CPU CACHE
- Again click "UNLOCK ADJUSTABLE VOLTAGE"
- Again using the slider under (Red Circle) "Offset Voltage" youre going to slide it back to 3/4 of what you used in Core Voltage. So if you did -100.6Mv like I did, you will use -75Mv.(Green Circle displays your current voltage offset) Remember you 3/4 of the Voltage you used in Core Voltage. So if you had -75mv you would use -50mv. or if you did -70 you would do -40. You can always figure out your max limit here as well and set it to that. Thats just my advice but you do not have to decrease your CPU CACHE to undervolt. you can skip this step if you like but it will reduce your temps even further. But it may also make your system more unstable as well with certain games and applications.
- Now go down to the bottom right and hit "Apply"
- Every time you start your PC these settings will reset so make sure you load Throttlestep EVERY time and set these settings. You will get use to it and do it in 10 seconds flat.
- If this method still fails to lower your temps, you can lower your clock speeds to downclock your CPU. Believe me when I say that if your CPU is overheating, this is going to actually increase performance. You will stop throttling and run at a lower clock speed which is still probably better than 70% base performance. Anyways, go under the tab (red circle)"TURBO RATIO LIMITS" And tune them down 1,2 or even 3 with the (Red Circle) slider. Try to make them all even or close. This is also how you overclock your CPU by turning them up
- Now you want to use something Cinebench R20 or R23 to test your stability and CPU score power. Its a benchmark tool and is free for the basic CPU test which is really all you need. Note: If you want to do some quick testing, just click the drop menu and turn it to "Off". This will just do 1 quick test instead of 10 minutes of testing. This way you can rapid test different settings.
I hope this helps anyone! You can always send me a DM if you need more help

First and foremost I want to say thanks a million for taking your time to write this guide. As an additional option to #11 I would suggest starting throttlestop at boot with the task scheduler vs doing it manually only because I found it annoying lol. I take no credit as it's not mine just trying to help

I appreciate very much. ty! Np on the suggestion. All are welcome here
