Table 2. Mixed Processor Configurations - Intel SR2612UR Product Specification

Product Overview
When using a single processor configuration, you must install the processor into the processor
socket labeled CPU1. A terminator is not required in the second processor socket when using a
single processor configuration.
When two processors are installed, the following population rules apply:

Both processors must be of the same processor family.

Both processors must have the same front-side bus (FSB) speed.

Both processors must have the same cache size.

Processors with different speeds can be mixed in a system, given the prior rules are met.
If this condition is detected, all processor speeds 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 Corporation.
The following table describes mixed processor conditions and recommended actions for all
®
Intel server boards and systems that use the Intel
following two categories:

Fatal: If the system can boot, it goes directly to the error manager, regardless of
whether the "Post Error Pause" setup option is enabled or disabled.

Major: If the "Post Error Pause" setup option is enabled, the system goes directly to the
error manager. Otherwise, the system continues to boot and no prompt is given for the
error. The error is logged to the error manager.

Severity
Fatal The BIOS detects the error condition and responds as follows:
 Logs the error into the system event log (SEL).
 Alerts the Integrated BMC of the configuration error with an IPMI
command.
 Does not disable the processor.
 Displays "0194: Processor family mismatch detected" message
in the error manager.
 Halts the system.
