CAUTION: Intel Montvale processors cannot be intermixed with similar Montecito processors.
Processor speed and cache size must be identical for all processors in a system. Whether
upgrading, replacing or adding an additional processor, to ensure compatibility use processors
with identical part numbers.
Failure to observe this caution results in performance degradation or system failure.
Table B-6 lists the processor upgrades that are supported, and required system firmware levels
for each server.

IMPORTANT: HP Integrity rx3600 servers with 512MB DIMMs installed on an 8-DIMM Memory Carrier do not
support this processor upgrade. When upgrading to this processor on HP Integrity rx3600 servers with 512MB
DIMMs installed in an 8-DIMM Memory Carrier, the quads of 512MB DIMMs must each be replaced with a pair of
1 GB DIMMs.
This requirement applies only to HP Integrity rx3600 servers with 512MB DIMMs installed on an 8-DIMM Memory
Carrier. This requirement does not affect 512MB DIMMs together with the 24-DIMM Memory Carrier, or any other
size DIMMs together with the 8-DIMM Memory Carrier.
Upgrading Verses Adding On
If your HP Integrity server already contains one, or more, of the processors listed in Table B-6,
then follow the processor removal and replacement procedures (see “Removing and Replacing
a Dual-Core Processor” (page 218)) to add another processor. Updating the system firmware and
OS is unnecessary when adding another processor.
If your HP Integrity server does not currently contain one, or more, of the processors listed in
Table B-6, then a server upgrade is being performed, and system firmware and OS updates may
be necessary. After any necessary system firmware and OS updates are performed, follow the
processor removal and replacement procedures (see “Removing and Replacing a Dual-Core
Processor” (page 218)).
