I had one DIMM in, 256Mb, running freebsd.

It passed POST no problem, got through all the rc files, but then started
dying as soon as I logged in.

Your mileage may vary.

BTW do NOT use 300W power supplies. I blew 2 trying. You need 30A on
the +5V line. The 350W PSs I got do 32A on +5 and work great (and
seem to be of higher quality altogether too).

Watch out with the heatsinks you use on the Tyan Tiger, golden orbs
do NOT FIT with all the caps surrounding the CPUs. Use square or
WIDE (rectangular) heatsinks. A long one or circular one just wont fit.

BTW - anyone have experience running non-MP athlons on these boards? I
booted it with a couple and ran various jobs (dnetc, gromacs, g98,
bunch of compile jobs of said programs as well as a FreeBSD and linux
kernel among other things) and I've had no problems yet.
