SDRAM RAS Precharge Time: Defines the length of time that the Row
Address Strobe (RAS) is allowed to precharge. Options are “2” , “3” and
“Auto” (default).
System BIOS Cacheable: When set to “Enabled”, the System BIOS will
be cached for faster execution. The default setting is “Disabled.”
Video BIOS Cacheable: When set to “Enabled,” the graphics card’s
local memory will be cached for faster execution. The default setting is
“Disabled.”
CPU Latency Timer: This item sets a timing parameter for CPU access.
Since the CPU timing is determined by the system hardware, leave this
item at the default value. The default is “Enabled.”
Delayed Transaction: The chipset has an embedded 32-bit posted write
buffer to support delay transactions cycles. Enable to support compliance
with PCI specification version 2.1. The default is “Enabled.”
AGP Graphics Aperture Size: This option determines the effective size
of the AGP Graphic Aperture, where memory-mapped graphic data
structures are located.
Display Cache Frequency: This item sets the main memory frequency.
When you use an external graphics card, you can adjust this to enable the
best performance for your system.
System Memory Frequency: This item sets the frequency for the system
memory bus. If you have installed 133 MHz memory, you can change the
frequency to 133 MHz.
On-Chip Video Window Size: This item defines the size of the aperture
if you use an AGP graphics adapter. It refers to a section of the PCI
memory address range used for graphics memory. We recommend that you
leave this item at the default value.
*Onboard Display Cache Setting*
The items under this heading are used to set the parameters for dis-
play cache memory that may be optionally installed on your
mainboard. If you have display cache memory, we recommend that
you leave these items at the default settings.
