2.5.5 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. 2.5.6 OC Tuner [Keep Current Settings] This item allows you to automatically overclock the CPU and DRAM frequencies and voltage for an enhanced system performance. It also accelerates the CPU graphics performance to the extreme depending on the CPU graphics loading. Configuration options: [Keep Current Settings] [OC Tuner I] [OC Tuner II] Ensure that you installed an efficient CPU fan for CPU and graphics loading before selecting either [OC Tuner I] or [OC Tuner II]. To keep the current overclocking tuner status, select [Keep Current Settings]. 2.5.7 EPU and Performance Mode [Auto] EPU and Performance Mode lets you configure the power usage to boost or enhance system performance. [Auto]: [Max Power-Saving Mode]: Automatically adjusts the power usage based on the system load. Enables all power-saving settings for maximum energysaving condition. [EPU Mode]: Lowers the CPU core/cache voltage for the best energysaving condition. [Performance Mode]: Disables all power-saving settings to achieve a high system performance. 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. 2-20 Chapter 2: Getting started

2.5.5
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.
2.5.6
OC Tuner [Keep Current Settings]
This item allows you to automatically overclock the CPU and DRAM frequencies and voltage
for an enhanced system performance. It also accelerates the CPU graphics performance to
the extreme depending on the CPU graphics loading. Configuration options: [Keep Current
Settings] [OC Tuner I] [OC Tuner II]
Ensure that you installed an efficient CPU fan for CPU and graphics loading before
selecting either
[OC Tuner I]
or
[OC Tuner II]
. To keep the current overclocking tuner
status, select
[Keep Current Settings]
.
2.5.7
