3-4. Chipset Features Setup Menu
The 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 SETUP DEFAULTS option).
Figure 3-5. Chipset Features Setup
You can use the arrow keys to move between the items. Use PgUP, PgDn, + or - key to
change the values. When you have finished setting up the chipset, press ESC to go back to
the main menu.
SDRAM RAS-to-CAS Delay:
This field lets you control the number of DCLKs between a Row Active command and a
read or write command.
SDRAM RAS Precharge Time:
The precharge time is the number of cycles it takes for the RAS to accumulate its charge
before DRAM refresh. If insufficient time is allowed, refresh may be incomplete and the
DRAM may fail to retain data. This field applies only if synchronous DRAM is installed in
the system.
