Information Update 3This document provides updated information for your system on the following topics:• Quad-core processor upgrades• Memory mirroring with fully buffered DIMMs• System message update• LCD status messages update• System Setup program update• Memory capacity reporting• Installing a PERC5i SAS RAID controllerQuad-Core Processor UpgradesIf the front of your system chassis is labeled with a "II," your system is upgradeable to the Quad-CoreIntel® Xeon® Processor 5300 series when these processors become available. See support.dell.com forinformation on processor availability and upgrade options for your system.Memory Mirroring With Fully Buffered DIMMsAs in the previous generation of memory mirroring technology, mirroring with fully buffered DIMMs(FBDs) provides enhanced protection from memory failure events, enabling a more robust computingenvironment. The new generation of FBD memory mirroring provides a higher level of system reliabilityby providing protection against more complex, but rare, failures such as a multi-bit error on a pair ofFBDs within a mirrored branch.However, a limitation in the chipset prevents the FBD memory mirroring from recovering from a smallset of failures that could occur in specific circumstances. These circumstances include rare AdvancedMemory Buffer (AMB) hardware failures or a possible short circuit in the FBD connector. Althoughunlikely, this means that FBD memory mirroring cannot assure failover in all possible circumstances.System Message UpdateTable 1-1 lists a new system message and the probable cause and corrective action when the messageappears. System messages appear on the screen to notify you of a possible problem with the system.CAUTION: Only trained service technicians are authorized to remove the system cover and access any of thecomponents inside the system. See your Product Information Guide for complete information about safetyprecautions, working inside the computer, and protecting against electrostatic discharge.
