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]
[100:133]
[100:100]
2.5.5 DRAM Odd Ratio Mode [Enabled]
Allows you to enable or disable the 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] [DDR4‑933MHz] [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. Configuration options: [Keep Current
Settings] [Ratio First] [BCLK + Ratio Tuning]
Ensure that you installed an efficient 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]
2-22
DRAM speed is set to the optimized settings.
The BCLK frequency to DRAM speed ratio is set to 100:133.
The BCLK frequency to DRAM speed ratio is set to 100:100.
