Hi according to HP memo see the following answer hope it help:

DESCRIPTION After installing a different system board or processor in systems described in the "Scope," the systems may halt during POST and display an 1801 Microcode Patch Error with a prompt to press the F1 key to continue.
NOTE Pressing the F1 key will allow the system to continue. However, processor performance may not be optimized and the error will repeat each time the system is restarted. HP recommends that the microcode be updated to ensure optimum compatibility and performance.

You need to update your Intel processor microcode patch. This can be updated independently of the system BIOS. The latest microcode update for the d530 786B2:

If you use this and still see the POST error message, please go into F10 Setup under System Properties and report the detailed description, including the stepping, of the processor in your system.

Try downloading the 815 motherboard drivers on the right side of the page.

These are very different CPU's, and you should make sure the board accepts the new one. Check the manual.

ya'll need to flash (upgrade) your motherboard BIOS to allow it to be compatible with the new CPU's.

I bought a Compaq Computer, 2.0Ghz, 256MB, 20GB for my College project. When i put the power on, it restarts almost immediately (so many times repeatedly). Then after such reboots, it successfully brings a message "1801 - Microcode Patch Error" and a F1-Boot directive.
