Lock the DIMM into place by pushing the clips back on either end of the socket onto the
notches in the ends of the DIMM (see pictures below for details).
Removing a DIMM
Removing a DIMM is just the reverse: pull back the clips from the DIMM (see pictures below), and care-
fully pull the module straight out. Place the DIMMs in an anti-static bag as soon as you remove them to
avoid static damage.
Unbuffered and Non-Registered vs. Registered Memory
The 168-pin DIMMs (Dual In-line Memory Modules) must be of the
3.3V PC100/PC133 unbuffered
vari-
ety. The notch position in the SDRAM key position will tell you whether or not a DIMM is unbuffered (see
Figure 2.1 below
). All installed memory will be auto-detected, so there is no need to set any jumpers.
