Hello It indicates the combination is unsupported. The CPUs must have matching specifications. If there is a difference between the CPUs in required specifications then the combination will be unsupported. This can be due to an unsupported CPU model combination or a faulty CPU. If one of the CPUs is experiencing issues then it may not be coming fully online. If the CPUs are of the same model then I suggest testing them one at a time in slot 1 to verify they are both functional. There are troubleshooting guides and other information in the documentation on the system support page. [URL] Thanks
I have the aforementioned error on my r815 server. does this mean one or both cpus have failed?
Unsupported cpu combination. Please install cpu1/2
