Cable Management
Always follow good cable management practices when working inside the computer.
Keep cables away from major heat sources like the heatsink.
Do not jam cables on top of expansion cards or memory modules. Printed circuit cards like these are not designed to take excessive pressure on them.
Keep cables clear of sliding or moveable parts to prevent them from being cut or crimped when the parts are moved.
When folding a flat ribbon cable, never fold to a sharp crease. Sharp creases may damage the wires.
Some flat ribbon cables come prefolded. Never change the folds on these cables.
Do not bend any cable sharply. A sharp bend can break the internal wires.
Never bend a SATA data cable tighter than a 30 mm (1.18 in) radius.
Never crease a SATA data cable.
Do not rely on components like the drive cage, power supply, or computer cover to push cables down into the chassis. Always position the cables to lay properly by themselves.
When removing the power supply power cables from the P1 or P3 connectors on the system board, always follow these steps:
Squeeze on the top of the retaining latch attached to the cable end of the connector (1).
Grasp the cable end of the connector and pull it straight up (2).
| CAUTION:
|
Always pull the connector - NEVER pull on the cable. Pulling on the cable could damage the cable and result in a failed power supply. |

Memory
The dx7300 and dc7700 series computers with Intel-based processors come with double data rate 2 synchronous dynamic random access memory (DDR2-SDRAM) dual inline memory modules (DIMMs).
| CAUTION:
|
DDR and DDR2 memory modules are not interchangeable. |
DDR2-SDRAM DIMMs
The memory sockets on the system board can be populated with up to four industry-standard DIMMs. These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum memory support, you can populate the system board with up to 8 GB of memory configured in a high-performing dual channel mode.
For proper system operation, the DDR2-SDRAM DIMMs must be:
industry-standard 240-pin
unbuffered PC2-4300 533 MHz-compliant, PC2-5300 667 MHz-compliant, or PC2-6400 800 MHz-compliant
1.8 volt DDR2-SDRAM DIMMs
The DDR2-SDRAM DIMMs must also:
In addition, the computer supports:
256Mbit, 512Mbit, and 1Gbit non-ECC memory technologies
single-sided and double-sided DIMMs
DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM are not supported
|
NOTE:
|
The system will not start if you install unsupported DIMMs. |
Populating DIMM Sockets
There are four DIMM sockets on the system board, with two sockets per channel. The sockets are labeled XMM1, XMM2, XMM3, and XMM4. Sockets XMM1 and XMM2 operate in memory channel A. Sockets XMM3 and XMM4 operate in memory channel B.

The system will automatically operate in single channel mode, dual channel mode, or flex mode, depending on how the DIMMs are installed.
The system will operate in single channel mode if the DIMM sockets are populated in one channel only.
The system will operate in a higher-performing dual channel mode if the total memory capacity of the DIMMs in Channel A is equal to the total memory capacity of the DIMMs in Channel B. The technology and device width can vary between the channels. For example, if Channel A is populated with two 256MB DIMMs and Channel B is populated with one 512MB DIMM, the system will operate in dual channel mode.
The system will operate in flex mode if the total memory capacity of the DIMMs in Channel A is not equal to the total memory capacity of the DIMMs in Channel B. In flex mode, the channel populated with the least amount of memory describes the total amount of memory assigned to dual channel and the remainder is assigned to single channel. For optimal speed, the channels should be balanced so that the largest amount of memory is spread between the two channels. For example, if you are populating the sockets with one 1GB DIMM, two 512MB DIMMs, and one 256MB DIMM, one channel should be populated with the 1GB DIMM and one 256MB DIMM and the other channel should be populated with the two 512MB DIMMs. With this configuration, 2 GB will run as dual channel and 256 MB will run as single channel.
In any mode, the maximum operational speed is determined by the slowest DIMM in the system.
Replacing Memory
| CAUTION:
|
The memory module sockets have gold metal contacts. When upgrading the memory, it is important to use memory modules with gold metal contacts to prevent corrosion and/or oxidation resulting from having incompatible metals in contact with each other.Static electricity can damage the electronic components of the computer or optional cards. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object. When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the module. |
-
Remove the access panel and rotate the computer so the system board is parallel to the table to make it easier to work on ( Access Panel
). | WARNING:
|
To reduce risk of personal injury from hot surfaces, allow the internal system components to cool before touching. |
Open both latches of the memory module socket (1), and insert the memory module into the socket (2).
|
NOTE:
|
A memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket. It may be easier to install a memory module in some cases if the main power cable from the power supply to the system board is temporarily disconnected. |
Push the module down into the socket, ensuring that the module is fully inserted and properly seated. Make sure the latches are in the closed position (3).
Repeat steps 3 and 4 for any additional modules that you want to install.
|
NOTE:
|
The computer automatically recognizes the additional memory when the computer is turned on. |
To reassemble the computer, reverse the removal procedure.
