[. . . ] Setting a high voltage may damage the CPU permanently, and setting a low voltage may make the system unstable. CPU VCCSA Offset Voltage [Auto] DRAM Voltage (CHA, CHB) [Auto] Allows you to set the DRAM voltage. DRAM Voltage (CHC, CHD) [Auto] Allows you to set the DRAM voltage. According to Intel CPU spec, DIMMs with voltage requirement over 1. We recommend you install the DIMMs with the voltage requirement below 1. CPU PLL Voltage [Auto] Allows you to set the CPU and PCH PLL voltage. KAWAI CP170 4-27 VTTCPU Voltage [Auto] Allows you to set the VTTCPU voltage. 1v Voltage [Auto] Allows you to set the 1. 5v Voltage [Auto] Allows you to set the 1. The values of the CPU Manual Voltage, CPU Offset Voltage, DRAM Voltage, VCCSA Voltage, VCCIO Voltage, CPU PLL Voltage, and PCH Voltage items are labeled in different color, indicating the risk levels of high voltage settings. The system may need better cooling system to work stably under high voltage settings. UEFI BIOS Utility - Advanced Mode Exit The items in this menu show the CPU-related information that the BIOS automatically detects. Enables the overheated CPU to throttle its clock speed to cool down. Hyper-threading [Enabled] The Intel Hyper-Threading Technology allows a hyper-threading processor to appear as two logical processors to the operating system, allowing the operating system to schedule two threads or processes simultaneously. [Disabled] [Enabled] Only one thread per activated core is enabled. Disabled for other OS (OS not optimized for Hyper-Threading Technology). Two threads per activated core are enabled. Enabled for Windows XP and Linux (OS optimized for Hyper-Threading Technology). KAWAI CP170 4-31 Active Processor Cores [All] Allows you to choose the number of CPU cores to activate in each processor package. Configuration options: [All] [1] [2] [3] [4] [5] [6] [7] Limit CPUID Maximum [Disabled] [Enabled] [Disabled] [Enabled] [Disabled] [Enabled] Allows legacy operating systems to boot even without support for CPUs with extended CPUID functions. Forces the XD feature flag to always return to zero (0). Execute Disable Bit [Enabled] Intel Virtualization Tech [Enabled] [Disabled] Allows a hardware platform to run multiple operating systems separately and simultaneously, enabling one system to virtually function as several systems. [. . . ] After the system reboots, an KAWAI Preload window appears. This option deletes only the partition you select from below, allows you to keep other partitions, and creates a new system partition as drive "C". This option deletes all partitions from your hard disk and creates a new system partition as drive "C". Follow the onscreen instructions to complete the recovery process. [. . . ]
