ASUS Z87-C
2.5.7 CPU bus speed : DRAM speed ratio mode [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 CPU bus speed to DRAM speed ratio is set to 100:133.
[100:100] The CPU bus speed to DRAM speed ratio is set to 100:100.
2.5.8 Memory Frequency [Auto]
Allows you to set the memory operating frequency. The conguration options vary with the
BCLK/PCIE Frequency item settings.
2.5.9 CPU Graphics Max. Ratio [Auto]
[Auto] Allows you to automatically optimize the CPU Graphics Ratio depending on
the system loading.
[Manual] Allows you to set a value for an optimal CPU Grapics Ratio. Use the <+> or
<-> keys to adjust the CPU graphics ratio. The minimum value depends on
the installed CPU.
2.5.10 OC Tuner [As Is]
OC Tuner automatically overclocks the frequency and voltage of CPU and DRAM for
enhancing the system performance and accelerates the iGPU performance to the extreme
according to the integrated graphics loading.
Conguration options: [As Is] [Ratio Only] [BCLK First]
2.5.11 EPU Power Saving Mode [Disabled]
Allows you to enable or disable the EPU power saving function.
Conguration options: [Disabled] [Enabled]
2.5.12 DRAM Timing Control
The subitems in this menu allow you to set the DRAM timing control features. Use the <+> or
<-> keys to adjust the value. To restore the default setting, type [auto] using the keyboard and
press the <Enter> key.
Changing the values in this menu may cause the system to become unstable! If this
happens, revert to the default settings.
2.5.13 DIGI+ VRM
CPU Load-line Calibration [Auto]
Load-line is dened by Intel
®
VRM specication and affects CPU power voltage. The CPU
working voltage will decrease proportionally to CPU loading. Higher load-line calibration could
get higher voltage and good overclocking performance, but increases the CPU and VRM
thermal conditions.
Select from Level 1 to Level 8 to adjust CPU power voltage from 0% to 100%.
The actual performance boost may vary depending on your CPU specication.
