BIOS Setup BIOS Setup
▶ Intel Turbo Booster
Ths tem wll appear when you nstall a CPU wth Intel Turbo Boost technology. Ths
tem s used to enable/ dsable Intel Turbo Boost technology. It can scale processor
frequency hgher dynamcally when applcatons demand more performance and TDP
headroom exsts. It also can delver seamless power scalablty (Dynamcally scale up,
Speed-Step Down). It s the Intel newly technology wthn newly CPU.
▶ DRAM Rato
Ths settng controls the rato of memory frequency to enable the memory to run at df-
ferent frequency combnatons.
▶ 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.
▶ Adjusted DRAM Frequency
It shows the adjusted DRAM frequency. Read-only.
▶ 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 Rate2
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.
