Adjusted CPU Frequency

It shows the adjusted CPU frequency. Read-only.

EIST

Enhanced Intel SpeedStep technology allows you to set the performance level of the

mcroprocessor whether the computer s runnng on battery or AC power. Ths eld only

appears wth nstalled CPUs that support ths technology.

Intel Turbo Boost 2.0

Enables or dsables Intel Turbo Boost 2.0 whch automatcally boosts CPU performance

above rated speccatons (when applcatons requests the hghest performance state

of the processor).

Drect OC Button

Ths tem allows you to enable/dsable the Drect OC buttons.

DRAM Frequency

Ths tem allows you to adjust the DRAM frequency. Please note the overclockng

behavor s not guaranteed.

Extreme Memory Prole (X.M.P)

Ths tem s used to enable/dsable the Intel Extreme Memory Prole (XMP). For further

nformaton please refer to Intel’s ocal webste.

Adjusted DRAM Frequency

It shows the adjusted DRAM frequency. Read-only.

DRAM Tmng Mode

Select whether DRAM tmng s controlled by the SPD (Seral Presence Detect) EE

PROM on the DRAM module. Settng to [Auto] enables DRAM tmngs and the followng

“Advanced DRAM Conguraton” sub-menu to be determned by BIOS based on the

conguratons on the SPD. Selectng [Lnk] or [Unlnk] allows users to congure the

DRAM tmngs for each channel and the followng related “Advanced DRAM Congura-

ton” sub-menu manually.

Advanced DRAM Conguraton

Press <Enter> to enter the sub-menu.

Command Rate

Ths settng controls the DRAM command rate.

tCL

Controls CAS latency whch determnes the tmng delay (n clock cycles) of startng

a read command after recevng data.

tRCD

Determnes the tmng of the transton 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 nsucent tme s allowed for RAS to accumulate before DRAM refresh, the DRAM

may fal to retan data. Ths tem apples only when synchronous DRAM s nstalled

n the system.
