Z270 Taichi VCCSA Voltage Configure the voltage for the VCCSA. VCC PLL 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. CPU Cold Bug Killer Voltage CPU Cold Bug Killer Voltage. Recommended to set 2.200V~2.400V for Ln2 benching. It will solve most of CPU cold bug. CLK VDD Voltage Configure the CLK VDD Voltage. DMI Voltage Some CPU request 1.400V~1.800V to get rid of cold bug. Especially benching 3D with Gen3 mode. 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. Save User Default Type a profile name and press enter to save your settings as user default. Load User Default Load previously saved user defaults. Save User UEFI Setup Profile to Disk Save current UEFI settings as an user default profile to disk. Load User UEFI Setup Profile from Disk Load previously saved user defaults from the disk. 69 English

VCCSA Voltage
Configure the voltage for the VCCSA.
VCC PLL 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.
CPU Cold Bug Killer Voltage
CPU Cold Bug Killer Voltage. Recommended to set 2.200V~2.400V for Ln2
benching. It will solve most of CPU cold bug.
CLK VDD Voltage
Configure the CLK VDD Voltage.
DMI Voltage
Some CPU request 1.400V~1.800V to get rid of cold bug. Especially benching 3D
with Gen3 mode.
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.
