OC Gene Button Operaton

Ths eld s used to enable/ dsable OC Gene functon.

DRAM Frequency

Ths settng controls the memory frequency to enable the memory to run at derent

frequency combnatons.

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 and the followng related “Advanced DRAM Congurat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

Ths controls the CAS latency, whch determnes the tmng delay (n clock cycles)

before SDRAM starts a read command after recevng t.

tRCD

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

setup tem allows you to determne the tmng of the transton from RAS (row ad

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

the DRAM performance.

tRP

Ths settng controls the number of cycles for Row Address Strobe (RAS) to be

allowed to precharge. If nsucent tme s allowed for the RAS to accumulate ts

charge before DRAM refresh, refreshng may be ncomplete and DRAM may fal

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

system.
