Processor Support

The server boards are designed to support one or two Intel
800 MHz front side bus with frequencies starting at 2.8 GHz. Previous generations of Intel Xeon
processors are not supported on either of these server boards.
The server board is designed to provide current up to 120 A per processors. Processors with
higher current requirements are not supported.

Note: Only Intel Xeon
these server boards. See the table below for the supported processors.

Note: The latest BIOS needs to be implemented before to have new Intel
supported on these server boards.

3.1.6.1 Processor Mis-population Detection
The processors must be populated in the correct order for the processor front side bus to be
correctly terminated. CPU socket 1 must be populated before CPU socket 2. Server board logic
will prevent the system from powering up if a single processor is present but it is not in the
correct socket. This protects the logic against voltage swings or unreliable operation that could
occur on an incorrectly terminated front side bus.
If processor mis-population is detected when using the standard onboard platform
instrumentation, the mBMC will log an error against processor 1 to the system event log and the
server board hardware will light both processor error LEDs.
