Intel S2600TP Technical Product Specification - Page 44

Processor Support Technical Product Specification  Both processors must have the same number of cores.  Both processors must have the same cache sizes for all levels of processor cache memory. Processors with different core frequencies can be mixed in a system, given 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. Processors that have different Intel® Quickpath (QPI) Link Frequencies may operate together if they are otherwise compatible and if a common link frequency can be selected. The common link frequency would be the highest link frequency that all installed processors can achieve. 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. 3.4 Processor Initialization Error Summary The following table describes mixed processor conditions and recommended actions for all Intel® server boards and Intel server systems designed around the Intel® Xeon® processor E52600 v3 product family and Intel® C610 chipset product family architecture. The errors fall into one of the following categories:  Fatal: If the system can boot, POST will halt and display the following message: "Unrecoverable fatal error found. System will not boot until the error is resolved Press to enter setup" When the 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. This operation will occur regardless of whether the BIOS Setup option "Post Error Pause" is set to Enable or Disable. If the system is not able to boot, the system will generate a beep code consisting of 3 long beeps and 1 short beep. The system cannot boot unless the error is resolved. The faulty component must be replaced. The System Status LED will be set to a steady Amber color for all Fatal Errors that are detected during processor initialization. A steady Amber System Status LED indicates that an unrecoverable system failure condition has occurred.  Major: If the BIOS Setup option for "Post Error Pause" is Enabled, and a Major error is detected, the system will go directly to the Error Manager screen in BIOS Setup to display the error, and logs the POST Error Code to SEL. Operator intervention is required to continue booting the system. If the BIOS Setup option for "POST Error Pause" is Disabled, and a Major error is detected, the Post Error Code may be displayed to the screen, will be logged to the 30 Revision 1.0
