Jumpers

DRAM Bus / QPI DRAM overvoltage setting

(3-pin OV_DRAM_BUS, 3-pin OV_QPI_DRAM)
These jumpers allow you to enable or disable the advanced DRAM Bus, and QPI DRAM

overvoltage settings in BIOS. Read the following information before you change the jumper

settings.

Before you change the jumper settings for extra-high overvoltage ability, use the BIOS

items first to adjust the desired DRAM, and QPI performance. Ensure that your system

functions well under the highest BIOS voltage settings before you change the setting

of these three jumpers.

The system may need a better cooling system (for example, a water-cooling system)

to work stably under high voltage settings.
