2. DRAM overvoltage setting (3-pin OV_DRAM)
This jumper allows you to enable or disable the DRAM overvoltage settings in BIOS.
Pins 1-2 (Enable OV)
Pins 2-3 (Default)
• Before you change the jumper settings for extra-high overvoltage ability, use the BIOS
items first to adjust the desired DRAM performance. Ensure your system functions
well under the highest BIOS voltage settings before you change the setting of the
jumper.
• The system may need a better cooling system, such as a water cooling system, to
maintain stability under high voltage settings.
