Processor Population Rules; Processor Initialization Error Summary - Intel S2600WF Technical Product Specification

Intel® Server Board S2600WF Product Family Technical Product Specification

Processor Population Rules

Note: The server board may support dual-processor configurations consisting of different processors that
meet the defined criteria below; however, Intel does not perform validation testing of this configuration. In
addition, Intel does not guarantee that a server system configured with unmatched processors will operate
reliably. The system BIOS does attempt to operate with processors which are not matched but are generally
compatible. For optimal system performance in dual-processor configurations, Intel recommends that
identical processors be installed.
When using a single processor configuration, the processor must be installed into the processor socket
labeled "CPU_1".
Note: Some server board features may not be functional unless a second processor is installed (see Figure
12).
When two processors are installed, the following population rules apply:
Both processors must have the same number of cores.
•
• Both processors must have the same cache sizes for all levels of processor cache memory.
• Both processors must support identical DDR4 memory frequencies.
Both processors must have identical extended family, extended model, processor type, family code
•
and model number.
Processors with FPGA and processors with Intel® Omni-Path Fabric cannot be mixed.
•
Processors with different core frequencies can be mixed in a system, given that the prior rules are met. If this
condition is detected, all processor core frequencies are set to the lowest common denominator (highest
common speed) and an error is reported.
Processor stepping within a common processor family can be mixed as long as it is listed in the processor
specification updates published by Intel. Mixing of steppings is only validated and supported between
processors that are plus or minus one stepping from each other.

Processor Initialization Error Summary

Table 9 describes mixed processor conditions and recommended actions for all Intel® server boards and
Intel server systems designed around the Intel® Xeon® processor E5-2600 v5 product family and Intel® C620
chipset architecture. The errors fall into one of the following categories:
• Fatal: If the system cannot boot, POST halts and display the following message:
Unrecoverable fatal error found. System will not boot until the error is
resolved
Press <F2> to enter setup
When the <F2> key on the keyboard is pressed, the error message is displayed on the error manager
screen and an error is logged to the system event log (SEL) with the POST error code.
The "POST Error Pause" option setting in the BIOS setup does not have any effect on this error.
If the system is not able to boot, the system generates a beep code consisting of three long beeps
and one short beep. The system cannot boot unless the error is resolved. The faulty component must
be replaced.
