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 Volt- age/ 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 be- havior 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) EE- PROM 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 Configura- tion” 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 (col- umn address strobe). The less clock cycles, the faster the DRAM performance.
