problem with 780G boards and Athlon 64 X2 5200+

I've had the same problem with a Athlon 64 X2 5200+ Brisbane in both a Gigabyte GA-MA78GPM-DS2H and an Asus M3A78-EM. Trying a fresh Vista intall, each board with it would BSOD after "copyig files"; if I hooked up a drive with the OS already intstalled, it would go into a reboot cycle at the beginning of the windows startup. I tried these boards wiith different RAM (working fine in other setups), tried removing peripherals, etc., nothing solved the problem. Tried with both 380W and 550W PS (both Antec), no difference.

Both boards have the latest bios and the CPU support lists say that bios supports the CPU.

Both boards work fine, however, with a 64 X2 3600+ or with a single core 3200+.

I'm starting to wonder if the CPU could be defective, however, both boards boot into the bios setup fine with it. (I have always thought that if the CPU had a problem you couldn't even get power on.)

Do I have a defective CPU or is something else going on?

Your default voltage on the board may not be adequate for the 5200. Try upping the cpu voltage by .1 volts. And check the default memory voltage. Bumping that up by .1 may also improve stability.

Thanks, I had tried bumping up the memory voltage by .1 and .2, but never thought to try raising the CPU voltage.

What bios version are you using? The board should automatically detect the correct voltage for your chip. If you're not overclocking, you shouldn't have to manually set voltages. Admittedly, I don't know the nuaces of your particular board.

I agree that the board should select the correct voltage for the CPU (which the boards identify correctly)

I am using the latest bios rev for each board (I did check released versions on the support sites). The bios supports the CPU per the boards' CPU support lists.
