RAS Timing
This option regulates the speed of the Row Address Strobe (RAS) as
either "Fast" or "Slow." As with CAS Latency, lowering the timing can
increase the speed of the SDRAM, but at the expense of stability.
RAS Pre-charge
The precharge time is the number of cycles it takes for the RAS to accumu-
late a charge before a DRAM refresh. Insufficient recharge time may cause
the DRAM to lose data. The settings are "Fast" and "Slow", which is more
stable.
System Memory Frequency
This option allows the system memory frequency to be adjusted. The set-
tings are "100 MHz" (for PC100 memory), "133 MHz" (for PC133 memory)
and "Auto", which allows the system memory frequency to auto select
itself
SDRAM Refresh
This option sets the refresh rate for the system memory. Settings include
"Auto", "15.6
m
S", "7.8
m
S" and "128 CLKS."
DRAM Cycle Time (SCLKS)
This option allows you set the DRAM cycle time to "5/7", "6/8" or "Auto."
CAS Latency (SCLKS)
This option allows you to set the CAS latency time to "3", "2" or "Auto."
RAS# to CAS# Delay (SCLKS)
The settings for this option are "3", "2" or "Auto."
RAS# Precharge (SCLKS)
This option sets the RAS# precharge time. The settings are "3", "2" or
"Auto."
