signal to accumulate its charge before the DRAM is refreshed. If insufficient
time is allowed, refresh may be incomplete and data lost.
Turbo Mode (Disabled)
This item allows you to speed up the external clock by approximately 2.5%.
This feature is used to verify the design flexibility. It is a very important tool for
test units to verify CPU stability. It is not recommended that you use this fea-
ture.
Command Pre Clock (Auto)
Leave this item at Auto to enhance the system performance.
DRAM Data Integrity Mode (Non-ECC)
Select Parity or ECC (error-correcting code), according to the type of installed
DRAM.
Memory Frequency For (Auto)
This item sets the main memory frequency. When you use an external graph-
ics card, you can adjust this to enable the best performance for your system.
System BIOS Cacheable (Disabled)
This item allows the system to be cached in memory for faster execution. En-
able this item for better performance.
Video RAM Cacheable (Disabled)
These items allow the video BIOS and RAM to be cached in memory for faster
execution. Enable these items for better performance.
Memory Hole At 15M-16M (Disabled)
You can reserve this area of system memory for ISA adapter ROM. When this
area is reserved, it cannot be cached. The user information of peripherals that
need to use this area of system memory usually discusses their memory
requirements.
Delayed Transaction (Enabled)
The chipset has an embedded 32-bit posted write buffer to support delayed
transaction cycles. Enable this item to support compliance with PCI specifica-
tion version 2.1.
AGP Aperture Size (128 MB)
This item defines the size of the aperture if you use an AGP graphics adapter.
The AGP aperture 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.
On-chip Frame Buffer Size (8M)
This allows you to set the VGA frame buffer size.
Delay Prior to Thermal (16 Min)
Enables you to set the delay time before the CPU enters auto thermal mode.
