Memory Upgrades on the HP Kayak XU800  
Memory Upgrades on the HP Kayak XU800  
There is a single Memory Expansion Card connector on the system board  
that supports a Memory Expansion Card installed with either RIMM or  
DIMM sockets.  
NOTE  
Do not install a memory module directly into a Memory Expansion Card  
connector on the system board.  
Depending on your PC Workstation, one of the following options is  
available:  
Four RIMM sockets. Each socket hosts 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. Upgrades are then installed in RIMM  
sockets A1-B1.  
RIMM socket A0  
RIMM socket B0  
RIMM socket A1  
RIMM socket B1  
Any unused RIMM sockets must contain a continuity module. If all  
sockets are used, store the continuity modules in a safe place for future  
upgrade possibilities. A RIMM memory module has several parameters  
that must be taken into consideration when upgrading memory:  
ECC Type. RIMM modules exist in either ECC or non-ECC versions.  
However, the HP Kayak XU800 PC Workstation supports only ECC  
RIMM modules.  
Speed Rating. Speed ratings for RIMM modules exist between: PC600  
to PC800. When upgrading memory, RIMM modules should only be  
installed with the same speed rating.

Four DIMM sockets. Each socket hosts SDRAM 100 MHz non-ECC  
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. Upgrades are then installed in DIMM sockets A1-B1.  
DIMM socket A0  
DIMM socket B0  
DIMM socket A1  
DIMM socket B1  
If any of the sockets are unused, leave them free, because a continuity  
module is not required. When upgrading the memory, always use the  
same type of SDRAM modules in pairs.

Installing Mass Storage Devices  
The PC has an integrated Ultra ATA-66 controller that supports up to four  
IDE devices. Removable media IDE devices, such as CD-ROM drives, DVD  
drives, tape drives and Zip drives, require front access. In addition to the  
floppy disk drive, your PC can support another 3.5-inch device plus two  
front-access 5.25-inch devices. Note that one front-access shelf may already  
have a CD-ROM drive installed in it.  
Refer to the drive’s manual to see if you must set jumpers or if there is a  
special installation procedure to follow.  
If you add an IDE Zip drive, hard disk drive, DVD drive, CD-ROM drive,  
CD-RW drive, or tape drive, you need to connect it to power and data  
cables. The data cables and connectors provided are shown below.

To identify the positions of other system board connectors, refer to the label located on the inside of the cover.  
Which SCSI  
Connectors to Use  
There is an internal SCSI connector on the system board that enables you  
to connect up to five internal SCSI devices. The last connector on the SCSI  
cable is connected to the onboard SCSI terminator, which in turn is  
connected to the external SCSI connector on the rear panel. This  
terminator is automatically deactivated when an external device is  
connected.  
If all the internal SCSI connectors are used, additional devices can be added  
outside the PC by connecting directly to the rear panel SCSI connector. The  
external connector allows up to ten external devices to be connected. This  
gives a maximum of 15 (internal + external) devices that can be connected.  
Before Installing a  
SCSI Hard Disk  
If you are installing an additional SCSI drive, you should assign an  
unused SCSI ID to this accessory. SCSI IDs range from 0 to 15 for  
Ultrawide 16-bit SCSI. SCSI ID 0 is used by the first SCSI hard disk drive  
and SCSI ID 7 is reserved for the integrated SCSI controller (the default for  
narrow and wide SCSI devices).

Installing and Replacing Hardware Parts in Your PC Workstation  
Installing Mass Storage Devices  
You should assign an unused SCSI ID to the second SCSI hard disk drive  
(for example, SCSI ID 1).  
The SCSI ID is usually configured with jumpers on the SCSI hard disk drive.  
Refer to the installation guide supplied with the drive for information on  
selecting a SCSI ID.  
Some internal SCSI disk drives may have termination resistors that must be  
removed or disabled before installation in your computer. Refer to the  
drive’s installation guide for more details and to see if there is a special  
installation procedure to follow.
