Hardware Upgrades  
Installing Additional Memory  
The computer comes with Synchronous dynamic random access  
memory (SDRAM) dual inline memory modules (DIMMs).  
DIMMs  
The memory sockets on the Intel 815E and 845 chipset-based system  
board can be populated with industry-standard DIMMs. These  
memory module slots are populated with at least one preinstalled  
memory module. To achieve the maximum memory support, you may  
be required to replace the preinstalled DIMM with a higher capacity  
DIMM.  
For proper system operation, the DIMMs must be industry-standard  
168-pin, PC133- compliant SDRAM DIMMs, depending on the  
model. The SDRAM DIMMs must support CAS Latency 2 or 3  
(CL = 2 or CL = 3). They must also contain the mandatory Joint  
Electronic Device Engineering Council (JEDEC) Serial Presence  
Detect (SPD) information. DIMMs constructed with x4 SDRAM are  
not supported; the system will not start using unsupported DIMMs.  
CAUTION: Some models support ECC memory and some support  
non-ECC memory. For those systems that do support ECC, Compaq  
does not support mixing ECC and non-ECC memory. Doing so will  
cause the system to blink the NUMLOCK LED on the keyboard  
continuously and, if a speaker is installed in the system, there will be a  
short beep followed by 2 long beeps. In addition, the system will not  
boot the operating system.

Hardware Upgrades  
Installing DIMMs  
CAUTION: Your memory module sockets have gold metal contacts.  
Ä
When upgrading your 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.  
CAUTION: 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. Refer to Appendix E, "Electrostatic Discharge,"  
for more information.  
Ä
Ä
CAUTION: When handling a memory module, be careful not to touch  
any of the contacts. Doing so may damage the module.  
1. Shut down the operating system properly, then power off the  
computer and any external devices, then disconnect the power  
cord from the power outlet.  
2. Remove the cover and locate the memory module sockets.  
WARNING: To reduce risk of personal injury from hot surfaces, allow  
the internal system components to cool before touching.

3. Open both latches of the memory module socket 1, and insert the  
memory module into the socket 2.  
Installing a DIMM  
Begin by installing a module into the socket nearest the  
preinstalled module, and install the modules following the  
numerical order of the sockets.  
A memory module can be installed in only one way. Match the  
notch on the module with the tab on the memory socket. Push the  
module down into the socket, ensuring that the module is fully  
inserted and properly seated 3.
