Hi I have a Dell Optiplex GX520 sff...
Running XP professional.
My cpu was a 2.6GHZ..
I have now upgraded to a Intel Pentium P4 661 Processor 3.60GHz 800FSB cpu / Part Number HH80552PG1042M / cpu Speed 3.6GHz / Package Type LGA775 L2 Cache 2 MB
I updated the system bios from the Dell support website
My pc works fine with it,except on start-up it states ¨incompatible cpu found¨ then askes to use F1 to start windows normaly or F2 keys to run system setup........but after pressing F1 it starts into windows and works fine and even shows the correct cpu values
I have tryed reseting the NVram (as advised) , but this seems to make no difference. Any suggestions ?

cheers
Pat
