HP Compaq 8000 Error 1802: Processor Not Supported

Question

I have an HP Compaq 8000 Elite Ultra Slim PC that I use as a server. Because it has an LGA775 core 2 duo, I bought a core 2 quad with the same socket (I don't know the exact model # of the CPU but it is a 2.5ghz quad core). Upon installation of the new hardware, my computer gave me a beep and a screen saying: "1802-Processor not supported The system board does not support this processor". Along with my computer information and menu options. I have updated my BIOS twice, my CPU microcode, and my Intel Management Engine firmware , but to no avail. Why is this problem still occouring? Is the CPU simply incompatible with my motherboard?

According to the Illustrated Parts and Service Map the only C2Q CPUs that can be used with it are the Q8400S, the Q9505S, and the Q9550S, none of which is a 2.5GHz part.

Using the 2.4 GHz 4 Core 8 MB cache CPU, my HP Compaq 8000 Elite Ultra Slim Desktop didn't want to work with this CPU: 2.83 GHz 12 Mb cache 4 core. After some research i do believe that only CPU with 65 Watts tdp can work in this PC, however i put to work the Q6600 here, only low power CPU whit 65 Watts tdp
