3. Inspect each cache memory chip; the pins should point
inward at slightly less than a 90° angle. If any of the pins
are bent or crooked, straighten them gently with your
fingers or with small tweezers to align them with the other
pins. Be careful when you do this; the pins are fragile and
can break off easily.
4. Position one of the cache chips over the first socket as shown
below, aligning the pins on the chip with the holes in the
socket. Align the small notch on the end of the chip with
the corresponding notch on the socket.

Gently press the chip halfway into the socket (to make sure
it is correctly aligned). If the chip goes in at an angle,
remove it and try again.
6. When the chip is properly positioned, push down firmly on
both ends of the chip to make sure it is well-seated.
7. Repeat steps 4 through 6 for each of the remaining chips.
8. Now install the tag SRAM chip in socket U30, next to the
SIMM sockets, as described in steps 4 through 6 of this
procedure. See “Locating System Board Components” to
locate the tag SRAM socket on the main system board.
