Cool your laptop by undervoltage
I will teach you how to reduce your temperatures when your laptop is at full load. With this method you can also save some power ( it means that your battery will last longer for example ).What type of disadvantages / risks this method has?
What type of disadvantages / risks this method has?
NONE.
This will not harm your laptop by any way. It wont affect your laptop performance when gaming, encoding,[etc...] because we wont be changing the frequency but yes the voltages.
Lets get started.
Firstly, we will need to download RightMark CPU Clock Utility which can be found Here.
* Open RM CPU Clock Utility
* Go to Profiles(click) - what you see are the multipliers that your CPU uses and the voltage
This was like an introduction. We will return here later
Next Step--------------------------------------------------------------------------------------------------------------------------
* Now click in Maximal Performance
* Click in OS Settings
Tick "Use OS power plan" and then select High Performance plan.
Next Step--------------------------------------------------------------------------------------------------------------------------
* Again in Maximal Performance, instead of OS Settings, change to CPU Settings
* Tick Use P-state transitions(for AC-Power and Battery) as shown in the image below
* Since it is Maximal Performance you will tick the highest multiplier available to have the highest CPU frequency
Next Step--------------------------------------------------------------------------------------------------------------------------
Lets go back where we were at the "introduction"(Click in Profiles). Here we will change the voltages to make the laptop cooler.
This is almost as overclocking, but here we will only mess with the voltages. Core 2 Duo's ( T7x00 / T5x00) use voltages between 1.0375v and 1.3v. If you have a CPU in these series, like me, you can go right away to 1.050 or even lower.
DO NOT TRY TO USE LOWER VOLTAGES THAN ITS ALLOWED TO!!!! Your laptop will likely not boot and to fix that you will have to clear the BIOS. For that you need to remove the CMOS battery and in laptops is kinda hard. You can still try, as I see some to try, and I will try.... But if your pc doesnt boot you are screwed.
Update: Got 0.987 in my CPU (T5600) and its recommended is 1.0357. Its safe. Tomorrow I will run stability tests.
To find which voltage your CPU accepts use this link here.
* Select for AC POWER in Current "Maximal Performance" since we want to lower the voltages to keep the laptop cool when at full load / gaming / etc...
* Leave No management for Startup
* Untick Auto-adjust intermediate states VIDs
* Start testing the voltages. Test one-by-one. When there instability, go back to the last voltage and that will be the minimum possible. Don't forget to click apply after changing the voltage.
Note: To check if it is working I would recommend downloading CPU-Z here.
After finding a stable voltage for your CPU for the higher multiplier you can do the same for the others multipliers of Maximum Perfomance plan.
If you wish to keep the voltages after exiting this program do this:
* Click in Management
* Untick Restore CPU defaults on management turning off and Restore CPU defaults on application exit
You can also do the same to Power Saving ( in this case we want low clocks [not the lowest or it will be extremely slow]). Change its voltages, etc...
To test your system for stability use Prime95 for full load and realtemp to monitor temperatures:
Download link: Prime95
Its all...
Any doubts post here.
If you find it hard to understand, please say and I will make it easier to understand.
