IntelTurbo Boost

Enables or disables Intel Turbo Boost which automatically boosts CPU performance above rated specifications (when applications requests the highest performance state of the processor).

OC Genie Button Operation

This item allows you to enable/disable the OC Genie function.

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.

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.

tRP

Controls number of cycles for RAS (row address strobe) to be allowed to pre-charge. If insufficient time is allowed for RAS to accumulate before DRAM refresh, the DRAM may fail to retain data. This item applies only when synchronous DRAM is installed in the system.

tRAS

Determines the time RAS (row address strobe) takes to read from and write to mem- ory cell.

tRFC

This setting determines the time RFC takes to read from and write to a memory cell.

tWR

Determines minimum time interval between end of write data burst and the start of a pre-charge command. Allows sense amplifiers to restore data to cell.
