I work a lot with hardware any my experience is that memtest is not very good at detecting errors. I have a Socket 7 board somewhere with bad L2 cache - it was unstable but memtest was unable to find anything. However, GoldMemory found some errors - they disappeared after disabling L2 cache and crashes disappeared too. It's not free but at least shareware - you can find it at http://www.goldmemory.cz/ The older version (IIRC 5.07) was better, I had problems with some of the newer ones on perfectly OK hardware (when the test should start, it rebooted instead). -- Ondrej Zary - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
