How good is your power supply? Only to be sure. You know about AMD's recommendations for a proper power supply if you are building an AMD Athlon/Duron system. Things going better with Athlon (MP) 4 and mobile Duron. The dual Athlon MP systems are another story... ...but smooth performer (I love it). MSI has a very good summary on there German website. I've piped it through Babel and sounds a bit funny, but anyway:-) [-] Ref NR: 09-0001 05.04.2001 Question/symptom: The operating system cannot be installed with my new MSI Main board. A cause: High requirements of electric current of new PCUs, diagram cards, large memory modules and some PCI cards (e.g. TV cards) provide for it that the usual 250 Watts of power packs the necessary performance any longer do not apply. Response/solution: MSI recommends to use a sufficiently dimmensioniertes power pack with following minimum values. +3.3 V - 20 ampere +5.0 V - 30 ampere Power packs with these values have usually a total output of ca.350 Watt. Please you consider however it by this also power packs give those the specification given above do not fulfill (server power packs) and therefore are unsuitable.

ASUS A7V/Thunderbird 1GHz lockup problems observation w/fix for me
Ever since building this system there have been spontaneous and unpredictable lockups, usually at least once per day. Sometimes several per day. The lockup is sometimes preceded by X starting to display things strangely (on a Voodoo 3 w/XF 4.X). Then I have a few minutes to reboot before it hangs (can't log in using ssh from another system.) With the Northbridge discussion, I couldn't pinpoint anything to fix it, so I started experimenting. Things got better by upgrading the BIOS; but still many hangs. I've discovered that changing the CPU voltage from the default to 1.75V results in a stable system. Higher than that doesn't work. Lower still gets lockups. It doesn't look like everyone has this problem with similar setups. But if there are others, I wanted to share this discovery. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
