Can you lower the voltage?
You can definitely lower the voltage on your MSP430 B660M with DDR4. It’s a common practice to undervolt for better performance or stability. Just make sure you adjust it carefully and monitor the system to avoid damage.
You're in the correct BIOS setting for undervolting. For Intel, you usually set the Core Voltage Offset to negative and apply an offset value, such as 50mV. The allowable offset depends on the chip—some processors tolerate -100mV while others need only -10mV for stability. To verify performance, OCCT is a solid choice. Demonstrating stability after undervolting can be challenging, but OCCT provides a reliable starting point.
Focus on the "cpu" benchmark alone, not combined with high memory. Run Linpack for 30 minutes to two hours. While testing, spin the mouse around the screen a few times occasionally to interrupt the test and trigger spikes, ensuring stability by checking for voltage drops.
I'm using an MSI board and I'm running the CPU Lite load mode. It's a straightforward tool—lower the settings until the system becomes stable. (I've gone from mode 18 to mode 10) Updated on October 17, 2025 by leclod
