Cross-posting is preferable to multi-posting. It is usually a good idea to
limit the number of newsgroups to three or fewer (some would say five or
fewer.) The only negative to cross-posting is when newsgroups with a very
high signal to noise ratio are included or some newsgroups that are a roost
for deliberate malicious pranksters that aim to disrupt discussions.

The problem you describe is a very difficult one to diagnose. Perhaps it is
a driver problem that only arises when certain events occur simultaneously.
Re-installing the drivers might help. Or not. That is what makes the
diagnosis difficult; it may take hours to see any results.

Have you tried the Orthos setting for stressing the CPU and memory (Blend -
stress CPU and RAM)?

Hi Thomas,
I have the same board, different (other stuff), and the same video card,
I'm not seeing this, although I am seeing a couple of strange things, such
as hanging occasionally during startup at the BIOS press DEL or TAB screen,
and sometimes Vista not starting.
What OS version are you using? Does the hang recover? Is the hang/freeze
total, i.e.. no mouse, no Ctl-Alt-Del response, no num lock/caps lock led
response?
I'm running the 0505 BIOS, I didn't know a newer version was out. I'll have
to give that a try.
Sorry, no answers, only questions!

Some more details: Running XP Pro. I even installed XP-Pro x64, to see if
that mattered. But the new install gave me the same problem (after
installing all the drivers, last driver was for the videocard).

This night I did another burn-in, still no problem.

To Phil, yes, I did use that Orthos test (also stress memory), but only for
an hour or 2.

I hope dearly that this BIOS upgrade helped me. Well, I'm off to work. Let's
see what the PC does.

Well, keeping my fingers crosses, my PC still seems to be functioning since
BIOS upgrade... But I'll refrain from doing anything extra-ordinary until
I'm certain it's fully stable...

The hang was total, the system didn't respond to ANYTHING. I could just use
the 'reset' button to get it back to life.

Well, I'm cooling the southbridge now, using a small Zalman block (only
4eu50, incredible).

I'm thinking about replacing the northbridge cooler as well. I've gotten the
CM Blue Ice. I hope it can just fit next to my Arctic Freezer 7. Any idea if
northbridge cooling can be removed without removing mainboard? If it can't,
I'll wait a week (stability isssue).

Last two days, I've had the same problem all over again. I'm going to try
and return the board. Pity I installed the southbridge, have to see if I can
clean the muck from the southbridge...

Apparently some tweaked memory settings took care of the
problem for some people here:

The "Jimmy Smith settings" may be worth a try!

Hey Jack,

I read on the web that 0602 AND 0505 are sh*t. I now downgarded to 0401.
This BIOS is stable, AND I can change my multiplier! Now running at 8 * 333
= 2667 MHz...

Good info, thanks!
Now, should I wait for a 'new and improved' BIOS version, or downgrade?
I'll grab a copy of 0401 while I ponder this...<g>
And, by the way, I'm coming to the conclusion that Vista is the OCer's worst
enemy.
I may have to stuff an XP drive in this system to prove.
