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.
Pins 1-2 (Default)
Pins 2-3 (OV Enabled)
• 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.
