I finally found another report of the same problem: http://h2np.net/tips/cpudcc.html (Japanese). This user has the same DFI motherboard, a slightly faster Althlon 64, and is running the same OS (Debian Sarge). He reports throttling failure after about 1 hour, the same as my case. To me this

Just for the record... because it works for me... I've tested this a Kingston dual kit (2 x 512MB DDR 400). The chips are in my first two DIMM slots. I've enabled Cool'n'Quiet in my bios if that matters. I'm currently unable to this w/o it has i don't have physical access to the machine at the mo
