System Memory

You can upgrade your system memory to a maximum of 16 GB by installing combinations of 256-MB, 512-MB, 1-GB, 2-GB, or 4-GB (when available) 2-way registered ECC PC2-3200 (DDR II 400) memory. The memory sockets are located on the system board adjacent to the power supply bays. See Figure 6-1.

NOTE: Two-way interleaving is not supported in the 256-MB single memory module configuration.

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 on the system board adjacent to the power supply bays. See Figure 6-1. The memory module sockets are arranged in three banks on two channels (A and B). The memory module banks are identified as follows:

Bank 1: DIMM1_A and DIMM1_B
Bank 2: DIMM2_A and DIMM2_B
Bank 3: DIMM3_A and DIMM3_B

General Memory Module Installation Guidelines

If only one memory module is installed, it must be installed in socket DIMM1_A or DIMM1_B.
If two or more memory modules are installed, they must be installed in pairs of 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.
Dual-ranked memory modules are not supported in bank 3.
If dual-ranked memory modules are installed in bank 2, you cannot install any memory modules in bank 3.

Memory modules marked with a 1R are single ranked and modules marked with a 2R are dual ranked. See Figure 6-15.

Figure 6-15. Determining a Memory Module's Capacity and Rank

Spare Bank Support

If six identical single-rank memory modules are installed, the memory modules in bank 3 (DIMM3_A and DIMM3_B) can function as a spare bank if you select the spare bank option using the System Setup program.

Memory Mirroring Support

The system supports memory mirroring if identical memory modules are installed in bank 1 and bank 2, and no memory modules are installed in bank 3.

Table 6-2 and Table 6-3 show examples of different memory configurations. Table 6-3 lists the various allowable combinations of single- and dual-ranked memory modules

Figure 6-16. Removing the Memory Cooling Shroud

Locate the memory module sockets. See Figure A-3.
Press the ejectors on the memory module socket down and out, as shown in Figure 6-17, to allow the memory module to be inserted into the socket.

Figure 6-17. Installing and Removing a Memory Module

Align the memory module's edge connector with the alignment key on the memory module socket, and insert the memory module in the socket.

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

Press down on the memory module with your thumbs while pulling up on the ejectors with your index fingers to lock the memory module into the socket.

When the memory module is properly seated in the socket, the ejectors on the memory module socket align with the ejectors on the other sockets that have memory modules installed.

Repeat step 3 through step 6 of this procedure to install the remaining memory modules. See Table 6-2 and Table 6-3 for sample memory configurations.
Replace the memory cooling shroud.
Close the system. See "Closing the System" in "Troubleshooting Your System."
(Optional) Press <F2> to enter the System Setup program, and check the System Memory setting on the main System Setup screen.

The system should have already changed the value to reflect the newly installed memory.

If the value is incorrect, one or more of the memory modules may not be installed properly. Repeat step 1 through step 10 of this procedure, checking to ensure that the memory modules are firmly seated in their sockets.
Run the system memory test in the system diagnostics. See "Running the System Diagnostics."

Removing Memory Modules

Open the system. See "Opening the System" in "Troubleshooting Your System."
Locate the memory module sockets. See Figure 6-1.
Press down and out on the ejectors on each end of the socket until the memory module pops out of the socket. See Figure 6-17.
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 a second processor. 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.

The following items are included in the processor upgrade kit:

Processor
Heat sink
Two processor cooling fans (if you are adding a second processor)

Replacing a Processor

Open the system. See "Opening the System" in "Troubleshooting Your System."
Remove the center fan bracket. See "Removing the Center Fan Bracket."

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.

Press the blue tab on the end of one of the heat-sink retention levers to disengage the lever, then lift the lever 90 degrees. See Figure 6-18.

Figure 6-18. Installing and Removing the Heat Sink

Wait 30 seconds for the heat sink to loosen from the processor.
Open the other heat sink retention lever.
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.
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 6-19.

Figure 6-19. 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.

Unpack the new processor.

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

Align the pin-1 corner of the processor with the pin-1 corner of the ZIF socket. See Figure 6-19.

NOTE: Identifying the pin-1 corners is critical to positioning the processor correctly.

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 7.

Apply thermal grease evenly to the top of the processor.
Place the heat sink onto the processor. See Figure 6-18.
Close one of the two heat sink retention levers until it locks. See Figure 6-18.
Repeat for the other heat sink retention lever.

Reinstall the center fan bracket. See "Replacing the Center Fan Bracket."
If you have added a second processor, install the two processor cooling fans for the new processor. See "Installing and Removing a Processor Fan."
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.
