User manual
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 Odd Ratio Mode, which provides better granularity.
Conguration options: [Disabled] [Enabled]
2.5.6 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: [DDR4‑800MHz] [DDR4‑933MHz] [DDR4‑1066MHz] [DDR4‑
1200MHz] [DDR4‑1333MHz] [DDR4‑1400MHz] [DDR4‑1500MHz] [DDR4‑1600MHz]
[DDR4‑1700MHz] [DDR4‑1733MHz] [DDR4‑1800MHz] [DDR4‑1866MHz] [DDR4‑1900MHz]
[DDR4‑2000MHz] [DDR4‑2100MHz] [DDR4‑2133MHz] [DDR4‑2200MHz] [DDR4‑2266MHz]
[DDR4‑2300MHz] [DDR4‑2400MHz] [DDR4‑2500MHz] [DDR4‑2533MHz] [DDR4‑2600MHz]
[DDR4‑2666MHz] [DDR4‑2700MHz] [DDR4‑2800MHz] [DDR4‑2900MHz] [DDR4‑2933MHz]
[DDR4‑3000MHz] [DDR4‑3066MHz] [DDR4‑3100MHz] [DDR4‑3200MHz] [DDR4‑3333MHz]
[DDR4‑3466MHz] [DDR4‑3600MHz] [DDR4‑3733MHz] [DDR4‑3866MHz] [DDR4‑4000MHz]
[DDR4‑4133MHz] [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 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. Conguration options: [Keep Current
Settings] [Ratio First] [BCLK + Ratio Tuning]
Ensure that you installed an efcient CPU fan for CPU and graphics loading before
selecting either [BCLK + Ratio Tuning] or [Ratio First]. To keep the current overclocking
tuner status, select [Keep Current Settings]
