CPU Frequency Multiple Setting [Auto]
This field sets the frequency multiple between the CPU's internal frequency (CPU
speed) and external frequency. Set this field in conjunction with CPU Frequency
(MHz) to match the speed of the CPU.
CPU Frequency Multiple [5.0x]
This field is available to unlocked processors only. For unlocked processors, this
field sets the frequency multiple between the CPU's internal frequency (CPU speed)
and the external frequency.
Configuration options: [5.0x] [5.5x]... ...[11.5] [12.0] [12.5x/13.0x]
System Performance [Optimal]
This field permits change of mode for system performance. When set to [Optimal],
the system uses the most stable settings. When you want to use overclocked settings
for higher performance but with higher risk of instability, set to [Aggressive] and to
allow full customization of performance options set to [User Defined]. Configuration
options: [Optimal] [Aggressive] [User Defined]
CPU Interface [Optimal]
This field sets the mode for CPU/FSB parameters usage. Select [Aggressive] if you
want to use overclocked CPU/FSB parameters. Otherwise, the default value is
[Optimal] where it uses the most stable CPU/FSB parameters. Configuration options:
[Optimal] [Aggressive]
Memory Frequency [By SPD]
This field sets the type of memory frequency based on the type of DDR (Double Date
Rate) memory module installed. Resulting frequency can vary depending on
percentage setting which is multiplied by the FSB frqequency. Normally, the default,
by SPD, permits autodetection. Configuration options: [By SPD] [50%] [60%] [66%]
[75%] [80%] [83%] [Sync] [120%] [125%] [133% [150%] [166%] [200%]
Resulting Frequency
This field displays the resulting memory frequency.
Memory Timing [Optimal]
This field permits change of memory timing mode for system performance. When set
to [User Defined], the next four fields can be set manually. Set to [Aggressive] for
higher performance. Use default [Optimal] to use most stable settings. Configuration
options: [Optimal] [Aggressive] [User Defined]
SDRAM Active Precharge Delay [7]
