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.

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
