3.
Turn off the computer properly through the operating system, then turn off any external devices.
4.
Disconnect the power cord from the power outlet and disconnect any external devices.
CAUTION:
You must disconnect the power cord and wait approximately 30 seconds for the
power to drain before adding or removing memory modules. Regardless of the power-on state,
voltage is always supplied to the memory modules as long as the computer is plugged into an
active AC outlet. Adding or removing memory modules while voltage is present may cause
irreparable damage to the memory modules or system board. If you see an LED light on the system
board, voltage is still present.
5.
Remove the computer access panel.
6.
Locate the memory module sockets on the system board.
WARNING!
To reduce risk of personal injury from hot surfaces, allow the internal system
components to cool before touching.
7.
Open both latches of the memory module socket (1), and insert the memory module into the socket
(2).
NOTE:
On HP Pro 2000 systems, populate the DIMM sockets in the following order: DIMM1 then
DIMM2.
On HP Pro 3000 systems with Intel processors, populate the DIMM sockets in the following order:
DIMM1, DIMM3, DIMM2, then DIMM4.
On HP Pro 3000 systems with AMD processors, populate the DIMM sockets in the following order:
DIMM1, DIMM2, DIMM3, then DIMM4

Installing a DIMM
NOTE:
A memory module can be installed in only one way. Match the notch on the module with
the tab on the memory socket.
8.
Push the DIMM module down firmly into the socket, ensuring that the module is fully inserted and
properly seated. The DIMM must be pushed all the way down into the socket and sit evenly in the
socket to avoid memory corruption. Make sure the latches are in the closed position (3).
9.
Repeat steps 7 and 8 to install any additional modules.
10.
Replace the computer access panel.
