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
SDRAM CAS Latency Time | Default: 3 |
SDRAM Cycle Time Tras/Trc | Default: 6/8 |
SDRAM | Default: 3 |
SDRAM RAS Precharge Time | Default: 3 |
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 | Default: Enabled |
Video BIOS Cacheable | Default: Enabled |
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 | Default: Disabled |
This item can be used to reserve memory space for some ISA expansion cards that require it.
CPU Latency Timer | Default: Disabled |
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 | Default: Enabled |
If the chipset has an embedded
| Default: 64 MB |
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.
