OC Gene

Settng ths tem to [Enabled] allows the system to detect the maxmum FSB clock and

to overclock automatcally. If overclockng fals to run, you can try the lower FSB clock

for overclockng successfully.

AMD Turbo Core Technology

Ths technology automatcally ncreases the frequency of actve CPU cores to mprove

performance.

Adjust Turbo Core Rato

Ths tem s used to adjust turbo core rato.

IGD Engne CLK

Ths tem s used to adjust ntegrated graphcs clock.

DRAM Frequency

Ths tem s used to adjust the DRAM frequency. Settng to [Auto], the system wll detect

the DRAM Frequency automatcally.

DRAM Tmng Mode

Select whether DRAM tmng s controlled by the SPD (Seral Presence Detect)

EEPROM on the DRAM module. Settng to [Auto] enables DRAM tmngs and the

followng “Advanced DRAM Configuraton” sub-menu to be determned by BIOS based

on the configuratons on the SPD. Selectng [Lnk] or [Unlnk] allows users to configure

the DRAM tmngs and the followng related “Advanced DRAM Configuraton” sub-menu

manually.

Advanced DRAM Configuraton

Press <Enter> to enter the sub-menu.

Command Rate

Ths settng controls the DRAM command rate.

tCL

Ths controls the CAS latency, whch determnes the tmng delay (n clock cycles)

before SDRAM starts a read command after recevng t.

tRCD

When DRAM s refreshed, both rows and columns are addressed separately. Ths

setup tem allows you to determne the tmng of the transton from RAS (row address

strobe) to CAS (column address strobe). The less the clock cycles, the faster the

DRAM performance.

tRP

Ths settng controls the number of cycles for Row Address Strobe (RAS) to be

allowed to precharge. If nsufficent tme s allowed for the RAS to accumulate ts

charge before DRAM refresh, refreshng may be ncomplete and DRAM may fal

to retan data. Ths tem apples only when synchronous DRAM s nstalled n the

system.

tRAS

Ths settng determnes the tme RAS takes to read from and wrte to memory cell.
