meaning of each option.
Item Option Description
•
Auto Configuration
Enabled Automatically configure DRAM Timing according
to the value of “DRAM Speed Selection”.
Disabled
Manually configure.
Note: It is recommended to choose “Enabled”
option for common users.
•
DRAM Speed
Selection
50ns,
60ns This item is of selected EDO DRAM read/write timing.
You must ensure that your DIMMs are as fast as 50ns,
otherwise you have to select 60ns.
•
MA Wait State Slow
Fast
One additional wait state is inserted before the
assertion of the first MA and CAS#/RAS# during
DRAM read or write leadoff cycles. This affects
page hit, row miss and page miss cases.
Without additional wait state.
•
EDO RAS# To CAS#
Delay
2 Add a delay time between the assertion of RAS#
and CAS#
3 Without additional delay time.
