Asus E7098, P8Z77-I, P8Z77IDELUXE DRAM CAS# Latency [Auto], DRAM RAS# to CAS# Delay [Auto], DRAM RAS# PRE Time [Auto], DRAM RAS# ACT Time [Auto], OC Tuner, EPU Setting [Auto], [Auto], [100:133]

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.

Memory Frequency [Auto]

Allows you to set the memory operating frequency. The configuration options vary with the BCLK/PEG Frequency item settings.

Selecting a very high memory frequency may cause the system to become unstable! If this happens, revert to the default setting.

iGPU Max. Frequency [Auto]

Allows you to set the iGPU maximum frequency. The values range from xxxxMHz (by CPU) to 3000MHz with a 50MHz interval. Use <+>/<-> to adjust the value.

EPU Power Saving Mode [Disabled]

Allows you to enable or disable the EPU power saving function. Configuration options: [Disabled] [Enabled]

EPU Setting [Auto]

This item appears only when you set the EPU Power Saving Mode item to [Enabled.] and allows you to select the EPU power saving mode. Configuration options: [Auto] [Light Power Saving Mode] [Medium Power Saving Mode] [Max Power Saving Mode]

OC Tuner

OC Tuner automatically overclocks the frequency and voltage of CPU and DRAM for enhancing the system performance. Configuration options: [OK] [Cancel]

DRAM Timing Control

The sub-items in this menu allow you to set the DRAM timing control features. Use the <+> and <-> 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.
