3-Core Ratio Limit [Auto] Select [Auto] to apply the CPU default Turbo Ratio setting or manually assign a 3-Core Limit value that must be higher than or equal to the 4-Core Ratio Limit. If you assign a value for 3-Core Ratio Limit, do not set the 1-Core Ratio Limit and 2-Core Ratio Limit to [Auto]. 4-Core Ratio Limit [Auto] Select [Auto] to apply the CPU default Turbo Ratio setting or manually assign a 4-Core Limit value that must be higher than or equal to the 3-Core Ratio Limit. 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] [DDR4-933MHz] [DDR4-1066MHz] [DDR41200MHz] [DDR4-1333MHz] [DDR4-1400MHz] [DDR4-1500MHz] [DDR4-1600MHz] [DDR41700MHz] Selecting a very high memory frequency may cause the system to become unstable! If this happens, revert to the default setting. 2.5.7 TPU [Keep Current Settings] TPU automatically overclocks frequency and voltage of CPU and DRAM to enhance the 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 that you use a water cooling device before selecting the TPU II mode. 2-20 Chapter 2: Getting started
