Technical Product Specification

Product Overview Intel® Server System SR2612UR TPS
4 Revision 1.3
Intel order number E76293-003
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
®
5520 Chipset. The errors fall into one of the
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.
Table 2. Mixed Processor Configurations
Error
Severity
System Action
Processor family not
identical
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.
Processor cache not
identical
Fatal
The BIOS detects the error condition and responds as follows:
 Logs the error into the SEL.
 Alerts the Integrated BMC of the configuration error with an IPMI
command.
 Does not disable the processor.
 Displays “0192: Cache size mismatch detected” message in the
error manager.
 Halts the system.
