If you assign a value for 4-Core Ratio Limit, do not set the 1-Core Ratio Limit, 2-Core Ratio Limit, and 3-Core Ratio to [Auto]. 2.5.4 BCLK Frequency: DRAM Frequency Ratio [Auto] Allows you to set the CPU bus speed to DRAM speed ratio mode. [Auto] DRAM speed is set to the optimized settings. [100:133] The BCLK frequency to DRAM speed ratio is set to 100:133. [100:100] The BCLK frequency to DRAM speed ratio is set to 100:100. 2.5.5 DRAM Odd Ratio Mode [Enabled] Allows you to enable or disable the DRAM Odd Ratio Mode, which provides better granularity. Configuration options: [Disabled] [Enabled] 2.5.6 DRAM Frequency [Auto] This item allows you to set the memory operating frequency. The configurable options vary with the BCLK (base clock) frequency setting. Select the auto mode to apply the optimized setting. Configuration options: [DDR4-800MHz] [DDR4-1066MHz] [DDR4-1333MHz] [DDR41400MHz] ~ [DDR4-4000MHz] [DDR4-4266MHz] Selecting a very high memory frequency may cause the system to become unstable! If this happens, revert to the default setting. 2.5.7 EPU Power Saving Mode [Disabled] ASUS EPU (Energy Processing Unit) sets the CPU in its minimum power consumption settings. Enable this item to set lower CPU VCCIN and Vcore voltages and achieve the best energy saving condition. Configuration options: [Disabled] [Enabled] 2.5.8 CPU SVID Support [Auto] Disabling SVID Support stops the processor from communicating with the external voltage regulator. Configuration options: [Auto] [Disabled] [Enabled] 2.5.9 DRAM Timing Control The subitems 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 keyboard and press the key. Changing the values in this menu may cause the system to become unstable! If this happens, revert to the default settings. 2-22 Chapter 2: Getting started

If you assign a value for 4‑Core Ratio Limit, do not set the 1‑Core Ratio Limit, 2‑Core Ratio
Limit, and 3‑Core Ratio to
[Auto]
.
2.5.4
BCLK Frequency: DRAM Frequency Ratio [Auto]
Allows you to set the CPU bus speed to DRAM speed ratio mode.
[Auto]
DRAM speed is set to the optimized settings.
[100:133]
The BCLK frequency to DRAM speed ratio is set to 100:133.
[100:100]
The BCLK frequency to DRAM speed ratio is set to 100:100.
2.5.5
DRAM Odd Ratio Mode [Enabled]
Allows you to enable or disable the DRAM Odd Ratio Mode, which provides better
granularity. Configuration options: [Disabled] [Enabled]
2.5.6
DRAM Frequency [Auto]
This item allows you to set the memory operating frequency. The configurable options vary
with the BCLK (base clock) frequency setting. Select the auto mode to apply the optimized
setting. Configuration options: [DDR4‑800MHz] [DDR4‑1066MHz] [DDR4‑1333MHz] [DDR4‑
1400MHz] ~ [DDR4‑4000MHz] [DDR4‑4266MHz]
Selecting a very high memory frequency may cause the system to become unstable! If this
happens, revert to the default setting.
2.5.7
EPU Power Saving Mode [Disabled]
ASUS EPU (Energy Processing Unit) sets the CPU in its minimum power consumption
settings. Enable this item to set lower CPU VCCIN and Vcore voltages and achieve the best
energy saving condition. Configuration options: [Disabled] [Enabled]
2.5.8
CPU SVID Support [Auto]
Disabling SVID Support stops the processor from communicating with the external voltage
regulator. Configuration options: [Auto] [Disabled] [Enabled]
2.5.9
DRAM Timing Control
The subitems 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
keyboard and press the <Enter> key.
Changing the values in this menu may cause the system to become unstable! If this
