Processor MultiplieBrIOS SETUP UTILITY This item will show when "Multiplier/Voltage Change" is set to [Manual]; otherwise, it will be hidden. You may set the value from [x8 1600 MHz] up to [x25 5000 MHz] but no higher than the value of "Processor Maximum Multiplier". For example, if the value of "Processor Maximum Multiplier" is [x11 2200 MHz], the actual value of multiplier will be [x11 2200 MHz] even if you set this item to a value higher than [x11 2200 MHz]. However, for system stability, it is not recommended to adjust the value of this item. Processor Voltage This item will show when "Multiplier/Voltage Change" is set to [Manual]; otherwise, it will be hidden. For safety and system stability, it is not recommended to adjust the value of this item. Memory Clock This item can be set by the code using [Auto]. You can set one of the standard values as listed: [100 MHz (DDR200)], [133 MHz (DDR266)], [166 MHz (DDR333)], [200 MHz (DDR400)]. Flexibility Option The default value of this option is [Disabled]. It will allow better tolerance for memory compatibility when it is set to [Enabled]. Burst Length Burst length can be set to 8 or 4 beats. 64 Bit Dq must use the 4 beats. CAS Latency (CL) Use this item to adjust the means of memory accessing. Configuration options: [Auto], [2.0], [3.0], and [2.5]. TRCD Use this to adjust TRCD values. Configuration options: [Auto], [2CLK], [3CLK], [4CLK], [5CLK], and [6CLK]. TRAS Use this to adjust TRAS values. Configuration options: [Auto], [5CLK], [6CLK], [7CLK], [8CLK], [9CLK], [10CLK], [11CLK], [12CLK], [13CLK], [14CLK], and [15CLK]. 31

Processor Multiplier
This item will show when “Multiplier/Voltage Change” is set to [Manual];
otherwise, it will be hidden. You may set the value from [x8 1600 MHz] up
to [x25 5000 MHz] but no higher than the value of “Processor Maximum
Multiplier”. For example, if the value of “Processor Maximum Multiplier” is
[x11 2200 MHz], the actual value of multiplier will be [x11 2200 MHz] even if
you set this item to a value higher than [x11 2200 MHz]. However, for
system stability, it is not recommended to adjust the value of this item.
Processor Voltage
This item will show when “Multiplier/Voltage Change” is set to [Manual];
otherwise, it will be hidden. For safety and system stability, it is not recom-
mended to adjust the value of this item.
Memory Clock
This item can be set by the code using [Auto]. You can set one of the
standard values as listed: [100 MHz (DDR200)], [133 MHz (DDR266)], [166
MHz (DDR333)], [200 MHz (DDR400)].
Flexibility Option
The default value of this option is [Disabled]. It will allow better tolerance for
memory compatibility when it is set to [Enabled].
Burst Length
Burst length can be set to 8 or 4 beats. 64 Bit Dq must use the 4 beats.
CAS Latency (CL)
Use this item to adjust the means of memory accessing. Configuration
options: [Auto], [2.0], [3.0], and [2.5].
TRCD
Use this to adjust TRCD values. Configuration options: [Auto], [2CLK], [3CLK],
[4CLK], [5CLK], and [6CLK].
TRAS
Use this to adjust TRAS values. Configuration options: [Auto], [5CLK], [6CLK],
[7CLK], [8CLK], [9CLK], [10CLK], [11CLK], [12CLK], [13CLK], [14CLK], and
[15CLK].
