DIMMs
DIMMs must be 168-pin unbuffered SDRAM
(synchronous dynamic random access memory),
compliant with the Intel
®
PC SDRAM Unbuffered
DIMM Specification
. The HP Pavilion ships with
one or more memory modules, but you can
replace the existing memory module(s) with
higher-capacity ones. You can install 64 MB,
128 MB, or 256 MB memory modules in the
computer.
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 module(s) with
higher-capacity ones. You can install 64 MB,
128 MB, or 256 MB memory modules in the
computer.
RIMMs
RIMMs must be 184-pin RDRAM (Rambus
dynamic random access memory), non-ECC (non-
error correction checking), compliant with the
Rambus/Intel specification.
The motherboard has four RIMM sockets that are
for a dual-channel configuration. The following
requirements must be met:
3
Rambus signaling level technology permits 600
and 800 MHz transfer rates. The HP Pavilion
uses PC600 or PC800 RDRAM modules.
3
All four RIMM sockets must be filled. If you do
not populate a socket with a RIMM, the empty
socket must be filled with a C-RIMM (continuity
RIMM). Two C-RIMMs are included on the
motherboard.
Note:
A C-RIMM does not contain any memory — it is
only a placeholder card used to close the
memory circuit. C-RIMMs are necessary to
avoid breaking the signal lines, which are a
serial connection in a Rambus interface; this
assures the electrical integrity.
