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 Min. CPU Cache Ratio [Auto] This item allows you to set the minimum possible ratio on the Uncore part of the processor. Use the or keys to adjust the value. The values depend on the CPU installed. 2.5.5 Max. CPU Cache Ratio [Auto] This item allows you to set the maximum possible ratio on the Uncore part of the processor. Use the or keys to adjust the value. The values depend on the CPU installed. 2.5.6 Internal PLL Overvoltage [Auto] Allows you to enable the internal PLL Overvoltage for K-SKU CPUs to get the extreme overclocking capability. Configuration options: [Auto] [Enabled] [Disabled] 2.5.7 CPU Ratio Tuner [Auto] This item allows you to enable or disable the CPU ratio tuner. Enabling this item may enhance the overclocking capability of non-K series CPUs. Configuration options: [Auto] [Enabled] [Disable] 2.5.8 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. 2.5.9 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: [DDR3-800MHz] [DDR3-1066MHz] [DDR3-1333MHz] [DDR3-1400MHz] [DDR3-1600MHz] [DDR3-1800MHz] [DDR3-1866MHz] [DDR3-2000MHz] [DDR3-2133MHz] [DDR3-2200MHz] [DDR3-2400MHz] [DDR3-2600MHz] [DDR3-2666MHz] [DDR3-2800MHz] [DDR3-2933MHz] [DDR3-3000MHz] [DDR3-3200MHz] [DDR3-3400MHz] Selecting a very high memory frequency may cause the system to become unstable! If this happens, revert to the default setting. 2.5.10 Max. CPU Graphics Ratio [Auto] Allows you to set the CPU Graphics ratio. Use / to adjust the value. The ratio may vary depending on the system loading. 2.5.11 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.
