2.CPU / DRAM Bus overvoltage settings (3-pin OV_CPU, 3-pin OV_DRAM_BUS)

These jumpers allow you to enable or disable the advanced CPU and DRAM Bus overvoltage settings in BIOS. Read the following information before you change the jumper settings.

 

 

OV_CPU

OV_DRAM_BUS

Pins 1-2

(Default)

up to 1.70V

up to 2.00V

Pins 2-3

(OV Enabled)

up to 2.10V

up to 2.46V

•Before you change the jumper settings for extra-high overvoltage ability, use the BIOS items first to adjust the desired CPU and DRAM performance. Ensure that your system functions well under the highest BIOS voltage settings before you change the setting of these jumpers.

•DO NOT set the OV_CPU jumper to pins 2–3 when you install a new CPU and have not booted for the first time. Doing so may cause the system to halt. For system failure due to the wrong setting of the OV_CPU jumper, shut down the computer and move the cap back to pins 1–2.

•According to Intel CPU spec, DIMMs with voltage requirement over 1.65V may damage the CPU permanently. We recommend you install the DIMMs with the voltage requirement below 1.65V.

•The system may need a better cooling system (for example, a water-cooling system) to work stably under high voltage settings.
