The Correct Undervolting Technique: Lower the Temperature to 10°C Without Buying a New Cooler!

Undervolting Guide for Beginners: Secure Step by Step

For beginners, the Undervolting process can seem technical and confusing. But with the right approach and systematic measures, you can do it safely to improve system efficiency without sacrificing performance.

Step 1: Advance Preparation (Mandatory!)

Before undervolting, make sure you have properly set up your tools and systems to prevent the risk of damage or data loss.

Required Software:

Preventive Measures:

1. Backup important data (anticipation of blue screen)
2. Record the default voltage and clock speed values
3. Make sure the BIOS is up-to-date (especially for laptops)
4. Do it in a stable working environment (do not undervolt when the laptop is in battery mode)

Step 2: Undervolting Steps

For Intel processors:

1. Open ThrottleStop
2. Click “FIVR”
3. In the “CPU Core Voltage” section:
   • Check “Unlock Adjustable Voltage”
   • Set “Offset Voltage” to -0.050V (50mV)
   • Click “Apply”

For AMD Ryzen Processors:

1. Open Ryzen Master
2. Select “Curve Optimizer”
3. Arrange:
   • All Core Negative Offset
   • Starting from -10
   • Test the stability of each 5-point drop

For GPUs (NVIDIA/AMD):

1. Open MSI Afterburner
2. Press Ctrl+F to open the curve editor
3. “Flatten Curve” Technique:
   • Select 900mV point
   • Pull the clock speed to the desired value
   • Flatten the curve after that point

Step 3: Start Undervolting Gradually

1. Lower 10 – 15 mV per experiment (don’t go straight to -100 mV!)
2. Save the profile of every change
3. Example of Initial Setting:
   • Intel CPU: -50mV offset
   • NVIDIA GPUs: Lower 50MHz every 25 mV

Step 4: Stress Test (Key to Success!)

After any voltage reduction, it is very important to test the stability of your system. This is to ensure that the CPU or GPU can still perform at its maximum without experiencing crashes or throttling.

Stability Testing Tools:

Success Indicators:

• The system did not experience a BSOD or a restart during testing
• No artifacts
• The benchmark score does not drop drastically compared to the default voltage
• Lower temperature 5-10°C but clock speed remains stable
