2. Remove the system front cover (see " Removing the Front Cover " in "Troubleshooting Your System").
3. Grasp the memory riser card ejectors, and rotate the ejectors up to release the card from the microprocessor board (see Figure 6 -8 ).
4. Lift the memory riser card straight up to clear the chassis.

Replacing the Memory Riser Cards
1. Position the memory riser card so that the card-edge connector is aligned with the riser card connector on the microprocessor board.
2. Lower the card into the chassis until the ejectors are in the memory riser card guides (see Figure 6 -8 ).
3. Rotate the ejectors levers down until the until the card is fully seated.
4. Replace the system front cover (see " Removing the Front Cover " in "Troubleshooting Your System").
Memory Modules
The memory modules are contained on two memory riser cards. Each riser card has eight memory module sockets. Between the two memory riser cards, the
system can accommodate from 512 MB to 16 GB of registered memory. The memory module sockets on each riser card are arranged in pairs (A and B) on four
banks (1–4). Memory modules must be installed in at least one bank on each memory riser card for the system to operate. The memory modules should be
installed starting with bank 1 and ending with bank 4 (see
Figure 6 -9 ). Each bank on each memory riser card must contain the same memory module size. For
example, if bank 1 on one riser card contains 128-MB memory modules, bank 1 on the other riser card must also contain 128-MB memory modules.
To obtain the desired total memory for your system, you may need to install memory modules of different sizes. This is supported as long as the memory
modules installed in each bank are the same size. For example, if you wanted the total memory in your system to be 6 GB, each memory riser card
configuration could be as follows:
Memory Upgrade Kits
The system is upgradable to 16 GB by installing combinations of 128-, 256-, 512-MB, and 1-GB registered memory modules. You can purchase memory upgrade
kits as needed.
Memory Module Installation Guidelines
Memory module sockets are arranged in pairs, labeled A and B, on each memory riser card. A pair of sockets on each memory riser card forms a single memory
bank. See
Figure 6 -9 to identify the sockets on a memory riser card.
NOTICE: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information document.
