DRAM RAS# to CAS# Delay
This field is used to insert a timing delay between the CAS and RAS
strobe signals, used when DRAM is written to, read from, or refreshed.
Fast gives faster performance; and Slow gives more stable performance.
This field applies only when synchronous DRAM have been installed in
the system. The settings are: 2,3,4,5 and auto.
DRAM RAS# Precharge
If an insufficient number of cycles is allowed for the RAS to accumulate
its charge before DRAM refresh, the refresh may be incomplete and the
DRAM may fail to retain data. Fast gives faster performance; and Slow
gives more stable performance. This field applies only when synchronous
DRAM is installed in the system. The settings are: 2,3,4,5 and Auto.
Precharge delay (tRAS)
If an insufficient number of cycles is allowed for the RAS to accumulate
its charge before DRAM refresh, the refresh may be incomplete and the
DRAM may fail to retain data. Fast gives faster performance; and Slow
gives more stable performance. This field applies only when synchronous
DRAM is installed in the system. The settings are: Auto and
2,3,4,5,6,7,8,9,10
System Memory Frequency
Default auto :The bios detect memory frequency is by SPD. The settings
are: Auto and 333MHz,400MHz,533MHz.
System BIOS Cache-able
Selecting Enabled allows caching of the system BIOS ROM at F0000h-
FFFFFh, resulting in better system performance. However, if any pro-
gram writes to this memory area, a system error may result. The settings
are: Enabled (Default) and Disabled.
Video BIOS Cacheable
Select Enabled allows caching of the video BIOS, resulting in better sys-
tem performance. However, if a program writes to this area, a system
error may result. The settings are: Enabled and Disabled (Default).
