CPU SVID Support [Auto] Set this item to [Enabled] when overclocking. Disabling this item prevents the CPU from communicating with the external voltage regulator. Configuration options: [Auto] [Disabled] [Enabled] The following items appear only when you set the CPU Core Voltage to [Auto] or [Disabled]. SVID Voltage Override[Auto] This item allows you to set a VCCIN for the CPU during initial part of POST. Use the or key to adjust the value. The values range from 0.001 V to 2.440V at 0.001V increment. SVID VDDQ Voltage Override [Auto] This item allows you to set a VCCIN for the CPU before OS loading. Use the or key to adjust the value. The values range from 0.001V to 2.440V at 0.001V increment. DRAM SVID Support [Auto] Set this item to [Disabled] to stop the CPU from communicating with the external voltage regulator. Disable this item when you overclock your system. Configuration options: [Auto] [Disabled] [Enabled] DRAM Voltage (CHA/CHB, CHC/CHD) [Auto] This item allows you to set the voltage for the system memory. Use the or key to adjust the value. The values range from 0.80V to 1.90V at 0.010V increment. According to Intel® CPU specifications, DIMMs with voltage requirement over 1.65 V may damage the CPU permanently. We recommend that you install the DIMMs with the voltage requirement below 1.65 V. PCH Core Voltage [Auto] This item allows you to configure the core voltage for the PCH (platform controller hub). Use the or key to adjust the value. The values range from 0.70V to 1.80V at 0.00635V increment. PCH I/O Voltage [Auto] This item allows you to configure the I/O voltage for the PCH (platform controller hub). Use the or key to adjust the value. The values range from 1.20V to 2.20V at 0.00635V increment. VCCIO CPU 1.05V Voltage [Auto] This item allows you to set the main power supply for the CPU REF. Use the or key to adjust the value. The values range from 0.7000V to 1.8000V at 0.00625V increment. Chapter 3 3-30 Chapter 3: BIOS setup
