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
The HP Pavilion uses PC600 or PC800 RDRAM
modules. Rambus signaling level technology
permits 600 and 800 MHz transfer rates.
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
ensures the electrical integrity.
3
RIMMs work in identical pairs, so they must be
from the same vendor, and have the same
speed, and memory size density within each
channel (see the memory table).
3
When C-RIMMs are used to fill empty sockets,
they must be placed in the RIMM A2 and
RIMM B2 sockets. The RIMMs must be inserted in
the RIMM A1 and RIMM B1 sockets.
