Advanced Chipset Features
This menu is used for memory functions settings. Such settings should be implemented cautiously since they can affect the stability of the whole system.

DRAM Timing Selectable
This submenu can be used for setting the optimum timing for options, depending on the memory modules used. By default the options are configured via 'By SPD', by reading the content of the SPD (Serial Presence Detect ) unit. During this process critical parameter information relating to memory type, size, speed, voltage interface and module banks are stored in the EEPROM.
System BIOS Cachable
If the function is active the cache memory makes use of the available BIOS-ROM, thereby enhancing the performance, although this applies mainly to DOS and Win3.x. Under Windows 95/98 this option is less relevant.
Video BIOS Cachable
If this option is enabled, the cache memory can take the VIDEO BIOS of the graphics card at the address C0000h to C7FFFh into account. Please note that caching involves risks, if the cache contains the code and a program wants to write into the BIOS area. If this option is enabled, the option Video BIOS Shadow should also be activated. Under DOS the speed benefits is around 40%. Under Win.x and DOS this option should be enabled, otherwise it should be disabled.
On-Chip Video Memory Size
This option can be used to set the size of the video memory. (128 MB, 256 MB)
On-Chip Frame Buffer Size
This option can be used to adapt the frame buffer. Various setting options are available. The individual options can be used to try and enhance the performance. Make sure the system stability is not affected and proceed step-by-step (1 MB, 4 MB, 8 MB)
Current Configuration
The current graphics configuration is shown here. In this device it is set to DVO.
Boot Type
This setting indicates the output source for the boot process. Since the CX50x0 devices support graphic outputs only via DVI-I, this setting is always set to DVI.
