OC Gene Button Operaton

Ths 󰘰eld s used to enable/ dsable OC Gene functon.

DRAM Rato

Ths settng controls the rato of memory frequency to enable the memory to run at df

ferent 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

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.
