HP Kayak XU800 PC Workstation

1-12 HP Kayak XU800 PC Workstation Minitower

PC Workstations

NOTE: The processor type and speed is automatically

recognized by the BIOS. This means that no particular

switch setting changes are required.

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: All models shipped with SDRAM memory should be

converted to RDRAM memory. Consult HP Support for

further information.

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.
