Processor Module Upgrades
6
Introduction
DIGITAL sells processor upgrade kits known as PowerGrade kits. Installing a
PowerGrade kit increases the capabilities of the server. This chapter describes the
configuration guidelines that must be followed prior to adding a Pentium Pro or
Pentium II processor as well as detailed procedures on removing and installing
processor modules.
NOTE: Installing an additional processor or changing
processor cards might involve updating the server’s BIOS.
To do this, you need to remove any video option card, if
installed, and enable the internal SVGA controller. Once
the BIOS update process successfully completes, you can
then reinstall any video option card. You must install the
new BIOS before installing another processor.
Processor Compatibility in a Multiprocessor
Environment
DIGITAL recommends using identical steppings/versions of processors within a
multiprocessor system whenever possible, since these configurations have received
the greatest amount of validation testing. Since it is not possible to validate every
combination of processor steppings, each new stepping of a processor is fully
validated only against the latest stepping. Refer to the readme file on the
ServerWORKS Quick Launch CD-ROM to view the latest processor compatibility
information.
