Chapter 2 2.6 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. Pins 1-2 (Default) Pins 2-3 (OV Enabled) OV_DRAM_BUS up to 2.00V up to 2.46V OV_QPI_DRAM up to 1.70V up to 1.90V • 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. 2-22 Chapter 2: Hardware information

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.
