I.18007 [I.18007] A power segment mismatch has been detected for one or more processor packages.
Explanation: The installed processors do not have the same power requirements.
Severity: Info
User response: Complete the following steps:
1. Ensure that all processors have matching power requirements (such as 65, 95, or 130 watts).
2. If power requirements match, check the IBM support site for any service bulletins or firmware updates that
apply to this processor error.
3. Replace one of the mismatching processors. While replacing the processor, inspect the processor socket and
replace the system board if the processor socket is damaged.
I.18008 [I.18008] Currently, there is no additional information for this event.
Explanation: The processors have mismatched internal DDR3 frequencies.
Severity: Info
User response: Complete the following steps:
1. Verify that matching processors are installed in the correct processor sockets, according to the product
documentation for the system. See the section entitled, "Installing the microprocessor and heat sink" for more
information.
2. Check the IBM support site for service bulletins or firmware updates that apply to this processor error.
3. Replace the associated processor. While replacing the processor, inspect the processor socket and replace the
system board if the processor socket is damaged.
I.18009 [I.18009] A core speed mismatch has been detected for one or more processor packages.
Explanation: The processors have mismatched core speeds.
Severity: Info
User response: Complete the following steps:
1. Verify that matching processors are installed in the correct processor sockets, according to the product
documentation for the system. See the section entitled, "Installing the microprocessor and heat sink" for more
information.
2. Check the IBM support site for service bulletins or firmware updates that apply to this processor error.
3. Replace the processor. While replacing the processor, inspect the processor socket and replace the system board if
the processor socket is damaged.
I.1800A [I.1800A] A mismatch has been detected between the speed at which a QPI link has trained between
two or more processor packages.
Explanation: The processors have mismatched bus speeds.
Severity: Info
User response: Complete the following steps:
1. Check the IBM ServerProven Web site to validate that the processor is a valid option for this system. If not,
remove the processor and install one that is a valid option.
2. Verify that matching processors are installed in the correct population sequence, according to the product
documentation for the system. See the section entitled, "Installing the microprocessor and heat sink" for more
information.
3. Check the IBM support site for service bulletins or firmware updates that apply to this processor error.
4. Replace the processor. While replacing the processor, inspect the processor socket and replace the system board if
the processor socket is damaged.
