According to documentation, you should just be able to socket replace your AMD Athlon (Socket AM2) with an AMD Phenom. Boot, and watch the bits fly. Well, theoretically.
In my Gigabyte’s case: this was not to be so. The smaller Gigabyte GA-MA69GM-S2H (blah!) is in our Media Center PC. This combination has been working well in production for months.
Continuous beeps (longish) from the Power-on-self-test (POST) indicates either power, memory, motherboard or somesuch failure. The Gigabyte documentation is 7 lines long and 7 pages short on helping.
OK, reading the procedures on forums and stuff.
It’s not the power supply. I can swap out the Phenom and Athlon with the same “everything” and it boots.
The Gigabyte online specifications state that the 9600 Black Edition (BE) is supported with a recent BIOS update. My BIOS has been at this update for the last 2 months in anticipation of the Phenom processor.
In short, wait people. Or at least research a little more than I did. Colleagues report that ASUS motherboards are work OK.
Oh the joys of hardware.
