BIOS Setup

▶My OC Genie Long duration maintained

This field allows you to customize Long duration maintained for OC Genie function.

▶My OC Genie Short duration power limit

This field allows you to customize Short duration power imit for OC Genie function.

My CPU Core Voltage/ My OC Genie CPU I/O Voltage/ My OC Genie DRAM Voltage/ My OC Genie GPU Voltage

These items are used to specific the voltage of CPU, Memory, GPU and chipset for OC Genie function.

Current CPU Core Voltage/ Current CPU I/O Core Voltage/ Current DRAM Voltage/ Current GPU Voltage

These items show current CPU/ CPU I/O/ DRAM/ GPU voltage. Read-only.

▶DRAM Reference Clock

This item allows you to specific the DRAM Reference Clock for CPU. Please note the overclocking behavior is not guaranteed.

▶DRAM Frequency

This item allows you to adjust the DRAM frequency. Please note the overclocking behavior is not guaranteed.

▶Adjusted DRAM Frequency

It shows the adjusted DRAM frequency. Read-only. ▶Extreme Memory Profile (X.M.P)

This item is used to enable/disable the Intel Extreme Memory Profile (XMP). For further information please refer to Intel’s official website.

▶DRAM Timing Mode

Select whether DRAM timing is controlled by the SPD (Serial Presence Detect) EEPROM on the DRAM module. Setting to [Auto] enables DRAM timings and the following “Advanced DRAM Configuration” sub-menu to be determined by BIOS based on the configurations on the SPD. Selecting [Link] or [Unlink] allows users to configure the DRAM timings for each channel and the following related “Advanced DRAM Configuration” sub-menu manually.

Advanced DRAM Configuration Press <Enter> to enter the sub-menu.

▶Command Rate

This setting controls the DRAM command rate.

▶tCL

Controls CAS latency which determines the timing delay (in clock cycles) of starting a read command after receiving data.

▶tRCD

Determines the timing of the transition from RAS (row address strobe) to CAS (column address strobe). The less clock cycles, the faster the DRAM performance.
