I have upgrade the BIOS to 1230 with ez flash 2. It was easy.
I follow this instructions.
I colud not resist and have put the CPU 3.2Ghz with the FSB 400. That is my goal. It is running OCCT. Lets hope it will work ok.

I confirm that now boot go all the way without the message "Unknown CPU detected, BIOS update required to unleash its full power".

One problem that I have and need your advice is about the voltage of the 12V, 5V and 3.3. The BIOS displays one information, the OCCT. With the multimeter I have diferent values.
In my OCZ 550W I can regulate the lines but wath should I take to guide me?
The last question is were do I measure the 3,3V with the multimeter.
