EiSt
Enhanced intel SpeedStep technology allows you to set the performance level of
the microprocessor whether the computer is running on battery or AC power. this
field only appears with installed Cpus that support this technology.
oC Genie Button operation
this field is used to enable/ disable the oC Genie function.
drAM ratio
this setting controls the ratio of memory frequency to enable the memory to run at
different frequency combinations.
Adjusted drAM frequency
it shows the adjusted drAM frequency. read-only.
drAM timing Mode
Select whether drAM timing is controlled by the Spd (Serial presence detect)
EEproM on the drAM module. Setting to [Auto] enables drAM timings and
the following "Advanced drAM Configuration" sub-menu to be determined by
BioS based on the configurations on the Spd. Selecting [Link] or [unlink] allows
users to configure the drAM timings for each channel and the following related
"Advanced drAM Configuration" sub-menu manually.
Advanced drAM Configuration
press <Enter> to enter the sub-menu.
Command rate
this setting controls the drAM command rate.
tCL
Controls CAS latency which determines the timing delay (in clock cycles) of
starting a read command after receiving data.
trCd
determines the timing of the transition from rAS (row address strobe) to CAS
(column address strobe). the less clock cycles, the faster the drAM perfor-
mance.
trp
Controls number of cycles for rAS (row address strobe) to be allowed to pre-
charge. if insufficient time is allowed for rAS to accumulate before drAM re-
fresh, the drAM may fail to retain data. this item applies only when synchro-
nous drAM is installed in the system.
trAS
determines the time rAS (row address strobe) takes to read from and write
to memory cell.
