X299 Killer SLI/ac VCCIO Voltage Configure the voltage for the VCCIO. CPU PLL1 Voltage Configure the voltage for the CPU PLL1. CPU PLL1 Eventual Voltage Configure the voltage for the eventual CPU PLL1. CPU PLL2 Voltage Configure the voltage for the CPU PLL2. CPU PLL2 Eventual Voltage Configure the voltage for the eventual CPU PLL2. Cold Bug Killer Cold Bug Killer Voltage. Recommended to set 2.200V~2.400V for Ln2benching. It will solve most of CPU cold bug. VCCSA Voltage Configure the voltage for the VCCSA. VCC PPL Voltage VCC PLL helps BCLK overclocking. Also this voltage rail is input source of CPU internal PLL voltage. Please set this voltage as 1.400V~1.500V when CPU is under LN2 benching. Very few CPU requests 2.500V~2.800V to get rid of cold bug. CLK VDD Voltage Configure the voltage for the CLK VDD. CPU Internal PLL Voltage Default is 0.900V. Each step is 0.015V. Adding 9- 15 steps will helps CPU PLL to lock internal clock during High frequency under Ln2 cooling. For example: 1.020V -1.125V will be proper value. But the voltage level will be different on each processor. User has to find the best value for your own processor. CPU Vcore Voltage must higher than CPU Internal PLL Voltage, or your processor will hang. CPU Core AC LoadLine AC Loadline defined in 1/100 mOhms. A value of 100 = 1.00 mOhm. and 1255 = 12.55 mOhm. Range is 0-6249 (0-62.49 mOhms). 0 = AUTO/HW default. UsesBIOS mailbox command 0x2. 71 English

CPU Internal PLL Voltage
Default is 0.900V. Each step is 0.015V. Adding 9- 15 steps will helps CPU PLL
to lock internal clock during High frequency under Ln2 cooling. For example:
1.020V -1.125V will be proper value. But the voltage level will be different on each
