Internal PLL Overvoltage [Auto]
This item allows you to enable Internal PLL Overvoltage for K-SKU and X-SKU CPUs to get
extreme overclocking capability.
Conguration options: [Auto] [Disabled] [Enabled]
BCLK Frequency : DRAM Frequency Ratio [Auto]
[Auto] The BCLK frequency to DRAM frequency ratio will be set to the optimized
setting.
[100:100] The BCLK frequency to DRAM frequency ratio will be set to 100:100.
[100:133] The BCLK frequency to DRAM frequency ratio will be set to 100:133.
DRAM Frequency [Auto]
This item allows you to set the memory operating frequency. The congurable options vary
with the BCLK (base clock) frequency setting. Select the auto mode to apply the optimized
