Advanced Chipset Features Option
This option displays a table of items that define critical timing
parameters of the System Board components including the
memory, and the system logic. Generally, you should leave the
items on this page at their default values unless you are very
familiar with the technical specifications of your system
hardware. If you change the values incorrectly you may
introduce fatal errors or recurring instability into your system.
Note that the page has a scroll-bar to scroll down to more items.
SDRAM CAS Latency Time
SDRAM Cycle Time Tras/Trc
SDRAM RAS-to-CAS Delay
SDRAM RAS Precharge Time
These four items set the timing and wait states for SDRAM
memory. We recommend that you leave these items at the
default value.
System BIOS Cacheable
Video BIOS Cacheable
These items allow the video and/or system to be cached in
memory for faster execution. We recommend that you leave
these items at the default value.
Memory Hole at 15M-16M
This item can be used to reserve memory space for some ISA
expansion cards that require it.
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.
Delayed Transaction
If the chipset has an embedded 32-bit write buffer to support
delay transaction cycles, you can enable this item to provide
compliance with PCI Ver. 2.1 specifications. We recommend
that you leave this item at the default value.
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.
