SDRAM Cycle Length
Default: 3
DRAM Clock
Default: Host CLK
These two items determine timing parameters for system memory. We
recommend that you leave these items at the default value.
Memory Hole
Default: Disabled
This item can be used to reserve memory space for some ISA expansion cards
that require it.
Read Around Write
Default: Disabled
Concurrent PCI/Host
Default: Disabled
These two items determine how the system organizes read/write operations over
the system’s memory and PCI buses. These items are determined by the
mainboard chipset so leave these items at the default value.
System BIOS Cacheable
Default: Disabled
Video BIOS Cacheable
Default: Disabled
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.
Video RAM Cacheable
Default: Disabled
This item determines if the system Video RAM can be cached to main memory
for faster execution. We recommend that you leave this item at the default value.
I/O Recovery Time
Default: Enabled
This item sets a timing parameters for legacy 8-bit and 16-bit ISA expansion
cards. We recommend that you leave these items at the default value Enabled.
AGP Aperture Size
Default: 64M
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.
AGP-2X Mode
Default: Enabled
This item lets you improve performance by doubling the speed of the AGP bus.
This function is supported by this mainboard so we recommend that you leave
this item at the default value Enabled.
Auto-Detect DIMM/PCI Clk
Default: Enabled
If this item is enabled, the system reduces EMI (electromagnetic interference) by
turning of the clock generator signal to DIMM slots or PCI slots that are
unoccupied.
Spread Spectrum
Default: Disabled
When this item is enabled, it can significantly reduce the EMI (electrical magnetic
interference) that your system generates. However, it can cause timing critical
devices, such as SCSI host adapters, to malfunction. We recommend that you
leave this item at the default value.
Current CPU Temp., Current System Temp., etc.
If you are using the hardware monitoring features of this system, you can use
these items to set thermal and electrical parameters for the system.
