▶ EIST
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 only
appears wth nstalled CPUs that support ths technology.
▶ Intel Turbo Boost
Enables or dsables Intel Turbo Boost whch automatcally boosts CPU performance
above rated specficatons (when applcatons requests the hghest performance state
of the processor).
▶ OC Gene Button Operaton
Ths tem s used to enable/dsable the OC Gene button operaton.
▶ DRAM Frequency
Ths tem allows you to adjust the DRAM frequency. Please note the overclockng be-
havor s not guaranteed.
▶ 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 for each channel and the followng related "Advanced DRAM Configura-
ton" sub-menu manually.
▶ Advanced DRAM Configuraton
Press <Enter> to enter the sub-menu.
▶ Command Rate
Ths settng controls the DRAM command rate.
▶ tCL
Controls CAS latency whch determnes the tmng delay (n clock cycles) of startng
a read command after recevng data.
▶ tRCD
Determnes the tmng of the transton from RAS (row address strobe) to CAS (col-
umn address strobe). The less clock cycles, the faster the DRAM performance.
▶ tRP
Controls number of cycles for RAS (row address strobe) to be allowed to pre-charge.
If nsufficent tme s allowed for RAS to accumulate before DRAM refresh, the DRAM
may fal to retan data. Ths tem apples only when synchronous DRAM s nstalled
n the system.
▶ tRAS
Determnes the tme RAS (row address strobe) takes to read from and wrte to mem-
ory cell.
▶ tRFC
Ths settng determnes the tme RFC takes to read from and wrte to a memory
cell.
