MSI A55M-P25-Serie Bedienungsanleitung Seite 26

Adjust CPU-NB ratio
this item is used to adjust CPU-NB ratio.
oC Genie
Setting this item to [enabled] allows the system to detect the maximum FSB clock
and to overclock automatically. if overclocking fails to run, you can try the lower
FSB clock for overclocking successfully.
AMd turbo Core technology
this technology automatically increases the frequency of active CPU cores to
improve performance.
Adjust turbo Core ratio
this item is used to adjust turbo core ratio.
iGd engine CLk
this item is used to adjust integrated graphics clock.
drAM Frequency
this is used to adjust the memory frequency.
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 [Manual] allows users to con-
figure the drAM timings and the following related "Advanced drAM Configura-
tion" sub-menu manually.
Advanced drAM Configuration
Press <enter> to enter the sub-menu. in this sub-menu you can adjust the ad-
vanced drAM timing.
Command rate
this setting controls the drAM command rate.
tCL
this controls the CAS latency, which determines the timing delay (in clock
cycles) before SdrAM starts a read command after receiving it.
trCd
When drAM is refreshed, both rows and columns are addressed separately.
this setup item allows you to determine the timing of the transition from rAS
(row address strobe) to CAS (column address strobe). the less the clock cy-
cles, the faster the drAM performance.
trP
this setting controls the number of cycles for row Address Strobe (rAS) to be
allowed to precharge. if insufficient time is allowed for the rAS to accumulate
its charge before drAM refresh, refreshing may be incomplete and drAM may
fail to retain data. this item applies only when synchronous drAM is installed
in the system.
