these are tests for a Pentium class cpu with a BX chipset
motherboard, which is why I slanted my response towards diode readings.
Last time I looked, there are K class tests included in cpuburn.
Try running 'burnK6'

Yes, Pentiums fail at ~65C, AMD's at ~90C BUT, both x86 processors
experience hickups at temps well below they're fail temps. More like
~50C plus a spike for both.

Your temps have to be from a probe... you must add ~20C to be on
the safe side. Even then thermistor should be at least in firm contact
with the center of the die, lightly greased, and shielded from the
hs/f's airflow. That Tbird could be hitting 70+C and is getting into
the lockup-reboot zone, if not close to failure. Which is the most
common RMA reason for returned Tbirds.

I agree, I've noticed a marked increase in cpu/cache/ram loads with
progressive upgrades of Mandrake 7.2, and even more with 8.0. It's not
Mandrake I believe, but the increasing intensity of XFree86, KDE,
Gnome, and such to become more like Winblows to the average Joe so he
can be won over. Dubious, IMO. 2.4.x kernels don't seem to be helpin
either ;(

Both are not what's needed. Silver is a gimmic, Volcano is
substandard. The $2 grease from Radio Shack is all I've ever used.
Thermaltake hs/fans suc. GlobalWin, or an Alpha, not Orbs. Still your
max temp should be kept under 50C, even if you use a $2 no-name
heatsink with a table fan pointed at it.
Keep in mind that temps vary (internally) very drastically. Often
10+C in a split fraction of a second. What you're seein' from a probe,
is a guess at best, an' won't indicate temp spikes (which cause random
reboots). It's like tryin to measure the temperature of the wiring in
a wall, by attaching a thermometer to the sheetrock. Almost useless.
AMD is finally getting up to speed, the new Athlon4's (Palomino's) will
have an internal diode to monitor actual core temp accurately.

No idea on memtest? It's a small deal, builds in a second. mprime
is as good a test, better in some ways, but you need to let it run in
the background for a day or so. Then look at the output for any error
lines.
Eric, not to be critical, but most problems in my experience are
best approached as user - hardware - OS, in that order. The problems
you're havin are not very likely due to 8.0 at all. If there's no
fundamental hardware problem (eg, heat), then configuration is the next
likely cause of locks/reboots. Ram timings, L2 cache latency, errant
bios settings and such. 'Course with the Tbird, power supplies are more
critical too. Watch the voltage outputs from lm_sensors. Particulary
the -12v, -5v readings. If they're low/vary, it's a wobbly PS. Also,
IIRC, you have a kk266 ? In any event, whatever motherboard, it's a
good idea to bump up the IO voltage (3.3v) on any mobo that supports
it. Most of the better ones have increased IOv by default. This will
greatly improve ram and overall motherboard stabiltity an' performance.
3.5 to 3.7 volts IO is the preferred. Also try your ram sticks in
different slots. If you've got more'n one stick, try putting 'em in
different order too.
Next thing to look at would be what pci cards you have in which
slots. Might need to move those around by trial'n error also. Look here
http://www.fullon3d.com/kk266faq/kk266faq.shtml#about
All'n all tho, random lockups-reboots are most often a hardware problem.
