Option Installation 3-9
SIMM UPGRADE
SIMM sticks are installed into SIMM sockets on the system board. The system board
provides four SIMM sockets and supports up to 128 MB of high-speed memory. The
system ships with two 8-MB EDO SIMMs already installed. The following 32-bit (non-
parity) 60 ns or 70 ns SIMMs are supported:
n
1-MB by 32-bit (4-MB stick)
n
2-MB by 32-bit (8-MB stick)
n
4-MB by 32-bit (16-MB stick)
n
8-MB by 32-bit (32-MB stick).
NOTE:
60 ns SIMMs can be installed, but they
will function at 70 ns.
CAUTION:
To avoid corrosion between
different metals, only use tin-plated SIMM sticks.
Checking System Memory
Use the following procedure to:
n
check the memory installed in the system
n
determine the SIMM configuration needed to increase memory
n
locate the sockets for SIMM installation.
1.
Locate the four SIMM sockets on the system board (see Figure Section 3-7).
If any cables block access to the SIMM sockets, label and disconnect them. If any
boards block access to the sockets, remove them.
2.
Use Table Section 3-1 to determine the SIMM configuration needed to upgrade
memory and to identify the sockets for SIMM installation.
