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] up to [x25] but no higher than the value of "Processor Maximum Multiplier". For example, if the value of "Processor Maximum Multiplier" is [x11], the actual value of multiplier will be [x11] even if you set this item to a value higher than [x11]. 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. You may set the value from [1.550V] down to [0.800V]. However, 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: [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]. Bank Interleaving Interleaving allows memory accesses to be spread out over banks on the same node, or accross nodes, decreasing access contention. Burst Length Burst length can be set to 8, 4 or 2 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]. The default value is [Auto]. TRCD Use this to adjust TRCD values. Configuration options: [Auto], [2CLK], [3CLK], [4CLK], [5CLK], and [6CLK]. The default value is [Auto]. TRAS Use this to adjust TRAS values. Configuration options: [Auto], [5CLK], [6CLK], [7CLK], [8CLK], [9CLK], [10CLK], [11CLK], [12CLK], [13CLK], [14CLK], and [15CLK]. The default value is [Auto]. TRP Use this to adjust TRP values. Configuration options: [Auto], [2CLK], [3CLK], [4CLK], [5CLK], and [6CLK]. The default value is [Auto]. MA Timing Use this to adjust values for MA timing. Configuration options: [Auto], [2T], [1T]. The default value is [Auto]. 27

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] up to [x25] but
no higher than the value of “Processor Maximum Multiplier”. For example, if
the value of “Processor Maximum Multiplier” is [x11], the actual value of
multiplier will be [x11] even if you set this item to a value higher than [x11].
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. You may set the value from [1.550V] down to
[0.800V]. However, 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: [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].
Bank Interleaving
Interleaving allows memory accesses to be spread out over banks on the
same node, or accross nodes, decreasing access contention.
Burst Length
Burst length can be set to 8, 4 or 2 beats. 64 Bit Dq must use the 4 beats.
