fered (see figure below). All installed memory will be automatically
detected, so there is no need to set jumpers. The TX chipset can cache
up to 64MB of RAM.
Make sure you do not attempt to install a 168-pin DIMM (shown
above) in a socket designed for a 72-pin SIMM (shown below), or vice-
versa.
Some details of memory installation:
s
SIMM modules must be installed in pairs.
s
Each pair of SIMMs must be of the same size and type.
s
The mainboard supports 4MB, 8MB, 16MB, 32MB, and 64MB
SIMMs.
s
SIMM banks 0, 1, and 2 can use either double- or single-sided
SIMMs.
s
Two SIMMs or one unbuffered DIMM must be installed for the
system to POST.
s
The mainboard supports 16MB, 32MB, and 64MB DIMM mod-
ules.
s
SIMM bank 0 and DIMM bank 0 cannot be used at the same time.
s
SIMM bank 1 and DIMM bank 1 cannot be used at the same time.
s
You can use SIMM bank 0 with DIMM bank 1.
s
You can use SIMM bank 1 with DIMM bank 0 (see motherboard
map on page 14).
s
If you use 4MBx64 DIMMs you cannot use SIMM bank 2.
s
We do not recommend using SIMM bank 2 along with DIMMs.
