upgrade iMac 7,1 2007 T9300

Hello, can someone tell me why after the processor update my mac shows this error? The seller assures me that the processor has been tested and works correctly.

Are you sure it's an iMac7,1? The panic says it's an iMac9,1, which uses 1066 MHz FSB CPUs. The T9300 has 800 MHz FSB, which might be problematic.
