Installing and Replacing Hardware Parts in Your PC Workstation Memory Upgrades on the HP Kayak XU800 Memory Upgrades on the HP Kayak XU800 NOTE 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. 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: Ì ECC Type. RIMM modules exist in either ECC or non-ECC versions. However, the HP Kayak XU800 PC Workstation supports only ECC RIMM modules. Ì 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. 13
