Internal PLL Overvoltage [Auto]
This item allows you to enable Internal PLL Overvoltage for K-SKU and X-SKU CPUs to get
extreme overclocking capability.
Conguration options: [Auto] [Disabled] [Enabled]
BCLK Frequency : DRAM Frequency Ratio [Auto]
[Auto] The BCLK frequency to DRAM frequency ratio will be set to the optimized
setting.
[100:100] The BCLK frequency to DRAM frequency ratio will be set to 100:100.
[100:133] The BCLK frequency to DRAM frequency ratio will be set to 100:133.
DRAM Frequency [Auto]
This item allows you to set the memory operating frequency. The congurable options vary
with the BCLK (base clock) frequency setting. Select the auto mode to apply the optimized
setting.
Conguration options: [Auto] [DDR4-800MHz] - [DDR4-4000MHz]
TPU [Keep Current Settings]
This item allows you to automatically overclock the CPU and DRAM frequencies and voltage
for an enhanced system performance.
[Keep Current Settings] Keep the current settings without changing anything.
[TPU I] Applies air cooling overclocking conditions.
[TPU II] Applies water cooling overclocking conditions.
Ensure to use water cooling device before selecting [TPU II].
EPU Power Saving Mode [Disabled]
The ASUS EPU (Energy Processing Unit) sets the CPU in its minimum power consumption
settings. Enable this item to set lower CPU core/cache voltage and achieve the best energy
saving condition.
Conguration options: [Disabled] [Enabled]
DRAM Timing Control
The sub-items in this menu allow you to set the DRAM timing control features. Use the
<+> and <-> keys to adjust the value. To restore the default setting, type [auto] using the
