This BIOS feature determines the signal strength between the chipset and the CPU. The higher the value, the stronger the signal. Due to the nature of this BIOS feature, it's possible to use it as an aid in overclocking the CPU. Your CPU may not overclock as well as you wanted it to. But by raising the CPU Drive Strength, it is possible to improve its stability at overclocked speeds. So, try values of 2 or 3 if your CPU just won't go the extra mile.

However, this is not a surefire way of overclocking the CPU. Increasing it to the highest value will not necessarily mean you can overclock higher. In addition, it's important to note that increasing the CPU Drive Strength will not improve its performance.

Although little else is known about the CPU Drive Strength feature, the downsides to a high CPU drive strength would probably be increased EMI (Electromagnetic Interference), power consumption and thermal output. Therefore, if you don't intend to overclock the CPU or it overclocks just fine at the default drive strength, it's recommended that you leave it at the default value.
