Do you have first-hand experience with power supply related problems? I thought I had fixed all problems with my Athlon box by swapping board, DIMMs and CPU, but after testing for a longer time I found that processes would still die with signal 11. The easiest way to cause such failures is an ApacheBench run with many concurrent dynamic requests (load >50) - after a while, (usually 30-60 minutes) several apache processes will die in a short period of time. I also had a prime factorization program crash after several hours (the "mprime" program from www.mersenne.org/gimps). Does that sound like a problem that could be related to the power supply? It's not one of the PSUs recommended by AMD, but rated at 300W. -mjy -- ***==> Marinos J.
