NOTE: A single-memory module configuration is not supported, and the maximum memory configuration depends on the availability of single-rank 2-GB memory modules.

NOTICE: If you remove your original memory modules from the system during a memory upgrade, keep them separate from any new memory modules that you may have. Use only registered ECC PC2-3200 compliant (DDR II 400) memory modules.

The system memory is located in sockets on the memory riser card(s). See Figure 6-10. The memory module sockets are arranged in two banks per riser card on two channels (A and B). The memory module banks are identified as follows:

Bank 1: DIMM_1A and DIMM_1B
Bank 2: DIMM_2A and DIMM_2B

Figure 6-10. Memory Riser Card Connectors

General Memory Module Installation Guidelines

If only two memory modules are installed on a memory riser card, they must be installed in sockets DIMM_1A and DIMM_1B.
Two memory modules installed as a pair must have matched memory size, speed, and technology.
The system supports both single-ranked and dual-ranked memory modules.
If you install both single-ranked and dual-ranked memory modules, the dual-ranked memory modules must be installed in bank 1.

Removing a Memory Riser Card Filler Blank

If you are adding an additional memory riser card, you will need to remove the filler blank installed in the location you are adding the new riser card. (The filler blanks are installed to direct cooling airflow if a memory riser is not installed.) To remove the filler blank, press the latch on the upper surface of the filler blank and slide the filler blank out of the system.

Locate the memory module sockets. See Figure A-3.
Press down and out on the ejectors on each end of the socket until the memory module pops out of the socket. See Figure 6-14.
Install the memory riser card that you wish to upgrade. See "Removing and Installing a Hot- Pluggable Memory Riser Card."
Close the system. See "Closing the System" in "Troubleshooting Your System."

Processor

You can upgrade the system processor(s) to take advantage of future options in speed and functionality, or add additional processors. Each processor and its associated internal cache memory are contained in a pin grid array (PGA) package that is installed in a ZIF socket on the system board.

Removing a Processor

Turn off the system and attached peripherals, and disconnect the system from the electrical outlet.
Open the system. See "Opening the System" in "Troubleshooting Your System."
Remove the cooling shroud. See "Removing the Cooling Shroud."

NOTICE: When you remove the heat sink, the possibility exists that the processor might adhere to the heat sink and be removed from the socket. It is recommended that you remove the heat sink while the processor is still warm.

NOTICE: Never remove the heat sink from a processor unless you intend to remove the processor. The heat sink is necessary to maintain proper thermal conditions.

While pressing firmly on the blue tab on the end of the heat-sink retention clip, compress the sides of the retention clip together until the clip disengages from the slots in the socket, and then slide the retention clip forward to release it from the back clips. See Figure 6-15.

Figure 6-15. Installing and Removing the Heat Sink

If the heat sink has not separated from the processor, carefully rotate the heat sink in a clockwise, then counterclockwise, direction until it releases from the processor. Do not pry the heat sink off of the processor.

NOTICE: If you are going to reinstall the same processor and heat sink, ensure that you do not disturb the thermal grease on either the processor or the heat sink.

Lift the heat sink off of the processor and set the heat sink upside down so as not to contaminate the thermal grease.
Pull the socket-release lever straight up until the processor is released from the socket. See Figure 6-16.

NOTICE: If you are removing processor 1 or processor 3, pull upward on the blue plastic tab next to the socket to open the socket-release lever.

Figure 6-16. Installing and Removing a Processor

Lift the processor out of the socket and leave the release lever up so that the socket is ready for the new processor.

NOTICE: Be careful not to bend any of the pins when removing the processor. Bending the pins can permanently damage the processor.

Installing a Processor

Turn off the system and attached peripherals, and disconnect the system from the electrical outlet.
Open the system. See "Opening the System" in "Troubleshooting Your System."
Remove the cooling shroud. See "Removing the Cooling Shroud."
Unpack the new processor.

If any of the pins on the processor appear bent, see "Getting Help."

If you are adding an additional processor, remove the processor filler blank from the socket by pressing inward on the two tabs on the filler blank and lifting the filler blank out of the system. See Figure 6-17.

Figure 6-17. Removing a Processor Filler Blank

Align the pin-1 corner of the new processor with the pin-1 corner of the ZIF socket. See Figure 6-16.

NOTICE: Identifying the pin-1 corners is critical to positioning the processor correctly. Pin-1 corners of processors 3 and 4 are opposite orientation of pin-1 corners of processors 1 and 2.

Identify the pin-1 corner of the processor by locating the tiny gold triangle on one corner of the processor. Place this corner in the same corner of the ZIF socket identified by a corresponding triangle.

Install the processor in the socket.

NOTICE: Positioning the processor incorrectly can permanently damage the processor and the system when you turn it on. When placing the processor in the socket, be sure that all of the pins on the processor enter the corresponding holes. Be careful not to bend the pins.

If the release lever on the processor socket is not positioned all the way up, move it to that position.

With the pin-1 corners of the processor and socket aligned, set the processor lightly in the socket, making sure all pins are matched with the correct holes in the socket.

Because the system uses a ZIF processor socket, do not use force, which could bend the pins if the processor is misaligned.

When the processor is positioned correctly, it drops down into the socket with minimal pressure.

When the processor is fully seated in the socket, rotate the socket release lever back down until it snaps into place, securing the processor.

Install the heat sink.
1. Using a clean lint-free cloth, remove the existing thermal grease from the heat sink.

NOTE: Use the heat sink that you removed in step 6.

Apply thermal grease evenly to the top of the processor.
Place the heat sink onto the processor. See Figure 6-15.
Squeeze the sides of the heat-sink retention clip together and press down on the blue tab. When the lower corners of the clip fit into the slots in the socket, release the sides of the clip to lock the heat sink in place. See Figure 6-15.

Reinstall the cooling shroud. See "Installing the Cooling Shroud."
Close the system. See "Closing the System" in "Troubleshooting Your System."

As the system boots, it detects the presence of the new processor and automatically changes the system configuration information in the System Setup program.

Press <F2> to enter the System Setup program, and check that the processor information matches the new system configuration.

See your User's Guide for instructions about using the System Setup program.

Run the system diagnostics to verify that the new processor operates correctly.

See "Running the System Diagnostics" for information about running the diagnostics and troubleshooting processor problems.

Installing A Processor VRM

The voltage regulator modules (VRMs) for Processor 1 and Processor 2 are installed on the system board. If you add a third and fourth processor, you must also install a VRM for each additional processor.

Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
Open the system. See "Opening the System" in "Troubleshooting Your System."
Locate the VRM socket for the processor you have added. See Figure A-3.
Press the ejectors on the VRM socket down and out, as shown in Figure 6-18, to allow the VRM to be inserted into the socket.

Figure 6-18. Installing a VRM

Align the VRM's edge connector with the alignment key on the socket, and insert the VRM in the socket. See Figure 6-18.

NOTE: The socket has an alignment key that allows you to install the VRM in the socket in only one way.

Press down on the VRM with your thumbs while pulling up on the ejectors with your index fingers to lock the VRM into the socket.
Close the system. See "Closing the System" in "Troubleshooting Your System."
Reconnect the system and peripherals to their power sources, and turn them on.
