BIOS Setup BIOS Setup
▶ DRAM Rato
Ths settng controls the rato of memory frequency to enable the memory to run at df-
ferent frequency combnatons.
▶ Adjusted DRAM Frequency
It shows the adjusted DRAM frequency. Read-only.
▶ Extreme Memory Profile(X.M.P)
Ths tem s used to enable/dsable the Intel Extreme Memory Profile (XMP). For further
nformaton please refer to Intel's offical webste.
▶ DRAM Tmng Mode
Select whether DRAM tmng s controlled by the SPD (Seral Presence Detect) EE-
PROM 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 ad-
dress strobe) to CAS (column address strobe). The less the clock cycles, the faster
the DRAM performance.
