No, it is not recommended to use RAM modules with different voltages in a dual-channel configuration. This is because dual-channel mode requires both modules to operate at the same speed and voltage to achieve optimal performance. If you use two RAM modules with different voltages, it can cause stability issues, reduce the overall performance of your system, and potentially damage the RAM modules or other components of your computer.
It is important to ensure that both RAM modules are identical in voltage, speed, and capacity when using them in a dual-channel configuration. This will help ensure that your computer is running at its optimal performance level and reduces the risk of any potential problems or damage.
