Cache Memory
The C586HX system board can support 256KB or 512KB pipeline burst,
direct map write-back cache SRAM. Your system board may come with
256KB or 512KB cache mounted at locations U22 and U23 of the sys-
tem board.
If your system board is mounted with 256KB cache, you may upgrade
your cache memory to 512KB by installing a 256KB cache module in
the 160-pin cache module slot (SSM1). Refer to page 12 for the loca-
tions of the SRAMs and cache module slot. If your system board is
mounted with 512KB cache, which is the maximum cache memory sup-
ported by the system board, the cache module slot will not be installed
on the system board.
Warning:
We highly recommend that you use the T2BSM32-256 cache module. If
you are using a cache module other than the one recommended above,
make sure your cache module meets the Intel COAST 2.x specification.
Severe damage might occur on the cache module or system board if
you insert modules other than those specified above.
Installing a SIM Module
A SIM module simply snaps into a socket on the system board. Pin 1 of
the SIM module must correspond with Pin 1 of the socket.
1. Position the SIMM above the socket with the “notch” in the module
aligned with the “key” on the socket.
2. Seat the module at a 45° angle into the bank. Make sure it is com-
pletely seated. Tilt the module upright until it locks in place in the
socket.
