Adjust Turbo Core Rato

Ths tem s used to adjust Turbo Core rato.

IGD Engne CLK

Ths tem s used to overclock the ntegrated graphcs.

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

Ths field has the capacty to automatcally detect the DRAM tmng.

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.

tRC

The row cycle tme determnes the mnmum number of clock cycles a memory row

takes to complete a full cycle, from row actvaton up to the prechargng of the actve

row.
