Chapter 3
3.5.12 ICH Voltage [Auto]
Allows you to set the I/O Controller Hub (ICH) voltage. The values range from 1.10V to 1.40V
with a 0.10V interval.
3.5.13 ICH PCIE Voltage [Auto]
Allows you to set the SB PCIE voltage. The values range from 1.50V to 1.80V with a 0.10V
interval.
3.5.14 DRAM Bus Voltage [Auto]
Allows you to set the DRAM voltage. The values range from 1.50V to 2.46V* with a 0.02V
interval.
• The value [2.46V] of the DRAM Bus Voltage item is supported only if the OV_DRAM_
BUS jumper is enabled, otherwise the maximum voltage supported is [1.90V]. See
2. CPU / DRAM Bus / QPI DRAM overvoltage setting on page 2-22 for details.
• 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 values of the CPU Voltage, CPU PLL Voltage, QPI/DRAM Core Voltage, IOH
Voltage, IOH PCIE Voltage, ICH Voltage, ICH PCIE Voltage, and DRAM Bus
Voltage items are labeled in different color, indicating the risk levels of high voltage
settings. Refer to the table below for details.
• The system may need better cooling system to work stably under high voltage
settings.

3.5.15 DRAM DATA REF Voltage on CHA/B/C [Auto]
Allows you to set the DRAM DATA Reference Voltage on Channel A/B/C. The values
range from 0.395x to 0.630x with a 0.005x interval. Different ratio might enhance DRAM
overclocking ability.
