3-4. Advanced Chipset Features Setup Menu
The Advanced Chipset Features Setup Menu is used to modify the contents of the buffers in
the chipset on the motherboard. Since the parameters of the buffers are closely related to
hardware, if the setup is not correct or is false, the motherboard will become unstable or you
will not be able to boot up. If you don’t know the hardware very well, use default values (i.e.
use the
Load Optimized Defaults
option). The only time you might consider making any
changes is if y ou discover that data is being lost while using your system.

the values. When you have finished setting up the chipset, press
Esc
to go back to the main
menu.
The first chipset settings deal with CPU access to DRAM. The default timings have been
carefully chosen and should only be altered if data is being lost. Such a scenario might well
occur if your system has mixed speed DRAM chips installed so that greater delays may be
required to preserve the integrity of the data held in the slower memory chips.
RDRAM Bus Frequency
This item allows you to select the running speed for the memory installed in your system.
Three options are available: 300MHz, 356MHz and 400MHz. We suggest you refer to your
RDRAM specification before you change this item setting. Furthermore, when you set the
CPU external frequency to 100MHz, only two options are available: 300MHz and 400MHz.
