System Performance (Normal Mode)
This is the DRAM auto configuration option, which can be set to Safe Mode,
Normal Mode, Fast Mode or Ultra Mode.
CAS Latency Setting (2.5T)
Enables you to select the CAS latency time in HCLKs of 2, 2.5, or 3. The
value is set at the factory depending on the DRAM installed. Do not change
the values in this field unless you change specifications of the installed DRAM
or the installed CPU.
DRAM Addr/Cmd Rate (Auto Mode)
This option allows you to set the lead off DRAM read and write cycles. When
set to Delay 1T, memory read/write commands are sent one clock cycle be-
hind the memory address. When set to Normal, read/write and memory
address commands are sent simultaneously.

AGP Aperture Size (128MB)
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.
