System Memory
The C586VX system board supports two kinds of memory modules:
DIMM and SIMM. DIMM, which uses SDRAM, performs better than
SIMM, which uses DRAM. Refer to page 12 for the locations of the DIM
and SIM sockets.
Note:
If a DIM module is installed in the DIMM socket, you can install SIM
modules in Bank 0 only. Do not install any SIM modules in Bank 1.
DIMM
The 168-pin DIMM (Dual In-line Memory Module) socket uses x64 EDO,
FPM and SDRAM. The C586VX system board can support 8MB to
16MB memory using 1MBx64 or 2MBx64 DIMM.
Installing the DIM Module
A DIM module simply snaps into a socket on the system board. Pin 1 of
the DIM module must correspond with Pin 1 of the socket.
1. Pull the “tabs” which are at the ends of the socket to the side.
2. Position the DIMM above the socket with the “notches” in the mod-
ule aligned with the “keys” on the socket.
3. Seat the module vertically into the socket. Make sure it is com-
pletely seated. The tabs will hold the DIMM in place.
