Install Memory - IBM M768MR User Manual

2: Mainboard Installation

Install Memory

The mainboard has two DIMM sockets for system memory
modules. You must install at least one memory module in order to
use the mainboard.
DIMM1
DIMM2
For this mainboard, you must use 168-pin, 3.3V unbuffered
SDRAM memory modules. If the installed CPU uses a 100MHz
system bus, you must use PC100 or PC133 memory. If the
installed CPU uses a 66MHz system bus, you must use PC66
memory. You can install any size memory module from 8 MB to
256MB, so the maximum memory size is 2 x 256MB = 512 MB.
The edge connectors on the memory modules have cut outs, which
coincide with spacers in the DIMM sockets so that memory
modules can only be installed in the correct orientation.
To install a module, push the retaining latches at either end of the
socket outwards. Position the memory module correctly and insert
it into the DIMM socket. Press the module down into the socket so
that the retaining latches rotate up and secure the module in place
by fitting into notches on the edge of the module.
