Is there a good site for pointers towards assembling reliable Linux
machines? It seems to me the trickiest part of the whole operation is
choosing good hardware in the first place. I just started a new job and
inherited a buch of new but flakey machines, and I'd like to avoid doing
that in the future.

The AMD duals have been a disaster in my experience. Its a shame because
when they do go they really are very fast boxes. The biggest factor I've
found is chipsets.

Why? ECC memory guards against a single bit error in the RAM, nothing
else, (except that it also reports double bit errors).

I do have a bunch of these running reliably (RH 7.3 plus the latest
OpenMosix kernel). I had to go through a few combinations of
motherboard and RAM (four different manufacturers of RAM) before I got
something that works. Processors are MP 1900+ or 2000+, boards are
Tyan S2466, memory is in PC2100 ECC registered 512MB sticks from
Corsair. Case and power supply are PC Power and Cooling, mid tower,
450W PS, every fan bay filled. These machines have been rock
stable for months except for a failed IBM deathstar drive and an
over-temp shutdown when the room AC failed.
I still have a couple of the 760MP boards (as opposed to the MPX
boards) which I just can't get to run properly with two processors.

Which chipset - the new or the old one? I've got an ASUS A7M266D (or
something) that's based on the AMD 760MPX chipset and has 512MB of
Registered ECC memory, and a pair of XP 1800+'s... and it works just
beautifuly. Truely rock solid.

Same board you have.
