Quad-Core Processor Upgrades

If the front of your system chassis is labeled with a "II," your system is upgradeable to the Quad-Core

Intel

Xeon

Processor 5300 series when these processors become available. See support.dell.com

for information on processor availability and upgrade options for your system.

Memory Mirroring With Fully Buffered DIMMs

As 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 computing

environment. The new generation of FBD memory mirroring provides a higher level of system reliability

by providing protection against more complex, but rare, failures, such as a multi-bit errors on a pair of

FBDs within a mirrored branch.

However, a limitation in the chipset prevents the FBD memory mirroring from recovering from a small

set of failures that could occur in specific circumstances. These circumstances include rare Advanced

Memory Buffer (AMB) hardware failures or a possible short circuit in the FBD connector. Although

unlikely, this means that FBD memory mirroring cannot assure failover in all possible circumstances.

System Message Update

Table 1-1 lists a new system message and the probable cause and corrective action when the message

appears. 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

the components inside the system. See your Product Information Guide for complete information about safety

precautions, working inside the computer, and protecting against electrostatic discharge
