The Enhanced Intel SpeedStep technology allows you to set the performance level of
the mcroprocessor whether the computer s runnng on battery or AC power. Ths field
wll appear after you nstalled the CPU whch supports speedstep technology.
DRAM Frequency
Ths settng controls the frequency of memory.
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)
EEPROM 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

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.
