Motherboard Manual Header for Memory Voltage Overclocking: JDDRII_2.3V When processing Memory Voltage Overclocking, please place the jumper to pin1-2 Closed. The Default setting is Pin 2-3 Closed. 3 1 13 Pin 1-2 Close: Memory voltage 2.3V. 13 Pin 2-3 Close: Normal status (default). Note: 1. When "JDDRII_2.3V" jumper cap is placed on Pin 2-3, memory voltage can be manually adjusted under CMOS setup. 2. When "JDDRII_2.3V" jumper cap is placed on Pin 1-2, memory voltage will be fixed at 2.3V automatically, and can't be adjusted under COMS setup. Before setting memory voltage overclocking, please ensure that your DDR supports up to 2.3V.
