[333MHz (DDRII667)] and [400MHz (DDRII800)]. Flexibility Option The default value of this option is [Disabled]. It will allow better tolerance for memory compatibility when it is set to [Enabled]. DRAM tCL Use this item to adjust the means of memory accessing. Configuration options are [6], [5], [4], [3] and [Auto]. DRAM tRCD This controls the latency between the DRAM active command and the read / write command. Configuration options: [2 DRAM Clocks], [3 DRAM Clocks], [4 DRAM Clocks], [5 DRAM Clocks], [6 DRAM Clocks] and [Auto]. DRAM tRP This controls the idle clocks after a precharge command is issued. Configuration options: [2 DRAM Clocks], [3 DRAM Clocks], [4 DRAM Clocks], [5 DRAM Clocks], [6 DRAM Clocks] and [Auto]. DRAM tRAS Thhis controls the number of DRAM clocks for TRAS. Configuration options: [4 DRAM Clocks], [5 DRAM Clocks], [6 DRAM Clocks], [7 DRAM Clocks], [8 DRAM Clocks], [9 DRAM Clocks], [10 DRAM Clocks], [11 DRAM Clocks], [12 DRAM Clocks], [13 DRAM Clocks], [14 DRAM Clocks], [15 DRAM Clocks] and [Auto]. Primary Graphics Adapter This item shows the primary graphics adapter. The default value is [PCI]. Configuration options: [Onboard], [PCI] and [PCI Express]. Internal Graphics Mode Select If you select [Auto], the onboard VGA will be automatically disabled when you install VGA card; the onboard VGA will be enabled without the installation of any add-on VGA card. If you select [Enabled, 8MB] or [Enabled, 1MB], the onboard VGA will be enabled. DVMT Mode Select Use this option to adjust DVMT mode. Configuration options: [Fixed Mode] and [DVMT Mode]. The default value is [DVMT Mode]. DVMT (Dynamic Video Memory Technology) is an architecture that offers breakthrough perfor mance for the motherboard through efficient memory utilization. In Fixed mode, a fixed-size fragment of the system memory is allocated to the graphics core. In DVMT mode, the graphics driver allocates memory as needed for running graphics applications and is cooperatively using this memory with other system components. This item will not be used under Windows® VistaTM OS because the driver will intelligently detect physical memory available and allocate necessary video memory. 34

[333MHz (DDRII667)] and [400MHz (DDRII800)].
Flexibility Option
The default value of this option is [Disabled]. It will allow better tolerance for
memory compatibility when it is set to [Enabled].
DRAM tCL
Use this item to adjust the means of memory accessing. Configuration
options are [6], [5], [4], [3] and [Auto].
DRAM tRCD
This controls the latency between the DRAM active command and the
read / write command. Configuration options: [2 DRAM Clocks], [3 DRAM
Clocks], [4 DRAM Clocks], [5 DRAM Clocks], [6 DRAM Clocks] and [Auto].
DRAM tRP
This controls the idle clocks after a precharge command is issued.
Configuration options: [2 DRAM Clocks], [3 DRAM Clocks], [4 DRAM
Clocks], [5 DRAM Clocks], [6 DRAM Clocks] and [Auto].
DRAM tRAS
Thhis controls the number of DRAM clocks for TRAS. Configuration
options: [4 DRAM Clocks], [5 DRAM Clocks], [6 DRAM Clocks], [7 DRAM
Clocks], [8 DRAM Clocks], [9 DRAM Clocks], [10 DRAM Clocks], [11
DRAM Clocks], [12 DRAM Clocks], [13 DRAM Clocks], [14 DRAM Clocks],
[15 DRAM Clocks] and [Auto].
Primary Graphics Adapter
This item shows the primary graphics adapter. The default value is [PCI].
Configuration options: [Onboard], [PCI] and [PCI Express].
Internal Graphics Mode Select
If you select [Auto], the onboard VGA will be automatically disabled when
you install VGA card; the onboard VGA will be enabled without the installa-
tion of any add-on VGA card. If you select [Enabled, 8MB] or [Enabled,
1MB], the onboard VGA will be enabled.
DVMT Mode Select
Use this option to adjust DVMT mode. Configuration options: [Fixed Mode]
and [DVMT Mode]. The default value is [DVMT Mode]. DVMT (Dynamic Video
Memory Technology) is an architecture that offers breakthrough perfor
mance for the motherboard through efficient memory utilization. In Fixed
mode, a fixed-size fragment of the system memory is allocated to the
graphics core. In DVMT mode, the graphics driver allocates memory as
