HP Kayak XU800 PC Workstation
NOTE:

Main Memory

The Kayak XU800 PC Workstation includes a single Memory Expansion Card
connector on the system board that supports a Memory Expansion Card
installed with either RIMM (Rambus In-Line Memory Module) or DIMM
(Dynamic In-Line Memory Module) sockets. Whether it is for a RIMM or DIMM
configuration, the maximum amount of memory that can be installed is 2 GB.
Memory Expansion Card with DIMM Sockets
NOTE:
There are four DIMM sockets with each socket supporting SDRAM 100 MHz or
133 MHz ECC unbuffered memory modules that are used in pairs. The first two
DIMM sockets (A0-B0), closest to the system board, contain the first pair of
memory modules. If any of the sockets are unused, leave them free, because a
continuity module is not required.
Models are supplied with a minimum of 128 MB of SDRAM unbuffered ECC
main memory. Memory upgrades are available in 128 MB, 256 MB, 512 MB and
1 GB unbuffered ECC SDRAM modules.
When upgrading memory, verify that:
SDRAM modules are installed in pairs (A0-B0 or A1-B1).
SDRAM modules are of the same type installed in pairs (A0-B0 or A1-B1).
Memory Expansion Card with RIMM Sockets
There are four RIMM sockets with each socket hosting RDRAM ECC memory
modules installed in pairs that must contain the same parameters per channel.
The first two RIMM sockets (A0-B0), closest to the system board, contain the
first pair of memory modules. Any unused RIMM sockets must contain a
continuity module.
Only ECC RIMM modules are supported. While speed ratings for RIMM modules
exist between: PC600 to PC800, when upgrading memory, paired RIMM modules
should only be installed with the same speed rating.
1-12 HP Kayak XU800 PC Workstation
The processor type and speed is automatically
recognized by the BIOS. This means that no particular
switch setting changes are required.
All models shipped with SDRAM memory should be
converted to RDRAM memory. Consult HP Support for
further information.
