About Installing DDR DIMMs
DDR DIMMs must be 184-pin unbuffered DDR
SDRAM (double data rate synchronous dynamic
random access memory). The HP Pavilion ships
with one or more memory modules, but you can
replace the existing memory modules with higher-
capacity ones. You can install 128 MB, 256 MB,
512 MB, or 1024 MB (1GB) memory modules in
the PC.
Note:
Some memory configurations vary, depending
on your PC model. 512 MB and 1024 MB DDR
DIMM memory modules are not compatible with
all PC models.
Removing a Memory Module
1 Remove the side panel that has thumbscrews.
See page 4.
2 Gently lay the PC on its side.
3 Locate the memory sockets on the
motherboard.
4 Move any cabling out of the way, if necessary.
5 Push down the two retaining clips on the ends
of the socket until the memory module pops out
of the socket. Hold the memory module by its
edges only, as you lift it away from the socket.
Store it in its antistatic packaging.
