3.4.17 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. 3.4.18 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. The highest value of the ICH PCIE Voltage item is limited by the DRAM Bus Voltage item. 3.4.19 DRAM Bus Voltage [Auto] Allows you to set the DRAM voltage. The values range from 1.20V 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 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 on the next page for details. • The system may need better cooling system to work stably under high voltage settings.
