Install Other Devices
For this mainboard, you must use 168-pin, 3.3V memory modules
installed with SDRAM memory chips. If you are using a processor
cartridge that runs on a 100 MHz system bus, you must use
memory that operates on a 100 MHz memory bus (PC-100
memory). If you are using a processor cartridge that runs on a 66
MHz system bus, you can use memory that operates on a 66 MHz
memory bus. You can install any size of memory module from 16
MB up to 256 MB, so the maximum memory size is 3 x 256 MB =
768 MB.
(2 x 256 MB = 512 MB if you have the 440 ZX version).
The edge connectors on the memory modules have cut outs, which
coincide with struts in the DIMM slots, so the memory modules
can only be installed in the correct way.
On the DIMM slot, pull the locking latches at either end of the
slots outwards. Position the memory module correctly and insert it
into the DIMM slot. Press the module down into the slot so that the
locking latches lever inwards and lock the module in place.
