Set Memory Voltage, Current Voltage 1.5v, Want 1.35v

1. Restart your computer: If your computer is currently running, you'll need to restart it to access the BIOS/UEFI setup.

2. Access BIOS/UEFI: During the boot process, you'll need to press a specific key to enter the BIOS/UEFI setup. This key varies depending on your motherboard manufacturer but commonly it's one of the following: Del, F2, F10, F12, or Esc. Check your motherboard manual or the initial boot screen for the correct key.

3. Navigate to the Voltage Settings: Once you're in the BIOS/UEFI setup, look for the section related to voltage settings. It might be labeled differently depending on your motherboard model. It could be under a section like "Advanced Settings," "CPU Settings," or "Overclocking Settings."

4. Adjust Memory Voltage: Within the voltage settings, locate the option for memory voltage. It might be expressed as "DRAM Voltage" or "Memory Voltage." Enter the desired voltage, in your case, 1.35V.

5. Save and Exit: After setting the desired voltage, save your changes and exit the BIOS/UEFI setup. Usually, there's an option to save and exit, or you might need to navigate to the exit menu to find the option to save changes and reboot.

6. Check Stability: Once your computer restarts, ensure that it boots up properly and runs stable. You may need to stress test your system or monitor it for any instability, especially if you've made other changes in the BIOS/UEFI setup.

Remember that adjusting voltages in the BIOS/UEFI setup can affect system stability and may void warranties, so proceed with caution and ensure you're comfortable with the changes you're making. If you're unsure, it's always a good idea to consult your motherboard manual or seek assistance from someone with experience in BIOS/UEFI settings.
