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 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.
2.5.8 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.
2.5.9 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.
2.5.10 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 First]
Ensure that you installed an efficient CPU fan for CPU and graphics loading before
selecting either [BCLK First] or [Ratio First]. To keep the current overclocking tuner
status, select [Keep Current Settings].
