The Enhanced Intel SpeedStep technology allows you to set the performance level of
the mcroprocessor whether the computer s runnng on battery or AC power. Ths 󰘰eld
wll appear after you nstalled the CPU whch supports speedstep technology.
DRAM Frequency
Ths settng controls the frequency of memory.
Extreme Memory Pro󰘰le(X.M.P)
Ths tem s used to enable/dsable the Intel Extreme Memory Pro󰘰le (XMP). For further
nformaton please refer to Intel’s o󰘲cal webste.
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)
EEPROM 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 Rate2
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.
