This controls the CAS latency, which determines the timing delay (in clock
cycles) before SDRAM starts a read command after receiving it. Settings:
[Auto], [CL=2.0], [CL=2.5], [CL=3.0]. [CL=2.0] increases the system perform-
ance the most while [CL=3.0] provides the most stable performance.
RAS# to CAS# delay (Trcd)
W hen 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
cycles, the faster the DRAM performance. Setting options: [Auto], [2 Bus Clocks],
[3 Bus Clocks], [4 Bus Clocks], [5 Bus Clocks], [6 Bus Clocks], [7 Bus Clocks].
Min RAS# active Time (Tras)
W hen the DDR Timing Setting by is set to [Manual], the field is adjustable.
This setting determines the time RAS takes to read from and write to a memory
cell. Setting options: [Auto], [5 Bus Clocks], [6 Bus Clocks], [7 Bus Clocks], [8
Bus Clocks], [9 Bus Clocks], [10 Bus Clocks], [11 Bus Clocks], [12 Bus Clocks],
[13 Bus Clocks], [14 Bus Clocks], [15 Bus Clocks].
Row Precharge Time (Trp)
This item 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. Available settings: [Auto], [2 Bus Clocks], [3 Bus Clocks], [4 Bus
Clocks], [5 Bus Clocks], [6 Bus Clocks].
High Performance M ode
This field allows you to select the DDR timing setting. Setting to [Optimized] enables
Adjust DDR Memory Frequency automatically to be determined by SPD. Selecting
[Manual] allows users to configure these fields manually. Setting options: [Optimized],
[Manual].
Aggressiv e T iming
This item allows you to enable or disable the memory clock. When [Enabled] is selected,
the timing delay of memory will be shorten to increase the performance. Setting
options: [Enabled], [Disabled].
Dynamic Overclocking
Dynamic Overclocking Technology is the automatic overclocking function, included in
's newly developed CoreCell
TM
the MSI
balance of CPU while running programs, and to adjust the best CPU frequency
automatically. W hen the motherboard detects CPU is running programs, it will speed
up CPU automatically to make the program run smoothly and faster. W hen the CPU is
temporarily suspending or staying in the low load balance, it will restore the default
settings instead. Usually the Dynamic Overclocking Technology will be powered only
when users' PC need to run huge amount of data like 3D games or the video process,
and the CPU frequency need to be boosted up to enhance the overall performance.
Setting options:
[Disabled] Disable Dynamic Overclocking.
