Hardware Reference Guide
There are four DIMM sockets on the HP Compaq dx2000 Microtower
system board, operating in either single- or dual-channel mode, with
two sockets per channel. The sockets are labeled J23, J24, J25, and
J28. Sockets J23 and J24 operate in memory channel A. Sockets J25
and J28 operate in memory channel B.
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.
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
more information.
CAUTION: When handling a memory module, be careful not to touch
any of the contacts. Doing so may damage the module.
1. Turn off the computer properly through the operating system and
turn off any external devices.
2. Disconnect the power cord from the power outlet and the
computer, and disconnect any external devices.
If there is a hard drive in bay 5 it will be necessary to remove the
lower drive cage before removing the memory modules.
3. Remove the right access panel.
WARNING: To reduce risk of personal injury from hot surfaces, allow
the internal system components to cool before touching.
4. Lay the computer down on its side to make it easier to work on.
