Hi Jason,
I run now still seti alone. Looks like the downclocking is gone.
one result looks very courious --> http://setiathome.berkeley.edu/result.php?resultid=1976573029
<core_client_version>6.12.26</core_client_version>

nothing in stderr ?

[Jason G]

Yeah, I'm convinced that's Boinc server or communications related somehow, & have seen empty stderr before with different applications. The newer exit code seems to have reduced the appearances of ones where stderr is truncated, but the whole thing missing isn't one I've been able to pin down to app or boinc client side yet.    One day I would like to think of a way to locate the exact point in the system where the stderr contents (or other parts) go missing, whether it's somewhere on our end, the server, or somewhere in between.

What, you don't have a dozen or so extras laying around? ...

LoL, yeah I'm running on the spare now, which has been a marathon juggling excercise:
- 750W psu aparently died,
- unplugged all hardware, including the GTX 480 for a test with spare 300W psu (success)
- checked 750W again ... nogo,
- harvested 450W PSU from lounge machine, repalcing it with the 300W
- removed GTX 260 from lounge machine replacing with old 9600GSO
- fiddled with drivers on that for ages to make sure that one's running & crunching OK (seems to be)
- Installed the 450W & another 9600GSO I had lying around in main machine to get it operational
- got that crunching OK & went to sleep

Still to come, see if the 450W can manage to drive the GTX 260 harvested from the lounge machine, not likely that it would manage the 480.  Lot's of tasks to crunch & the 9600GSO may have trouble beating deadlines, LoL.

Then I'll see if the supplier will RMA the 750W PSU.  Sheesh, best PSU I ever had (Seasonic X-750), runs stone cold & only last a year?  ... oh well...

Humm.  Not what I wanted to hear.       
A few weeks back I put together an i7-950 with the same exact PS...

It's been as Awesome PSU, never any sign of stress, or even getting warm.  Hopefully just a freak one-off.

It looks like fuse problem in PSU, not PSU itself But since you will not open PSU since you loose guarantee you will never know
Always you can look at bright side of life What if all other components dies, but not PSU. That will me far more damage.

P.S little advice.
Don't  mess with 450W PSU of lower quality and GTX 260. It is power hungry beast, and or PSU or GPU will be damaged is there is no sufficient power.
Yesterday I finally got more then 120 WU, so can start crunch normally at least 24 hours

LoL, I agree, but I've been trying to kill this GTX 260 & PSU (turns out now I look it's a thermaltake 470W, so not completely crap, but not enough for the 260)  for a long time so that I can justify getting a newer one for the machine it was in  ...

Yesterday I finally got more then 120 WU, so can start crunch normally at least 24 hours   

Besides, I have ~2400 tasks on this machine, if something dies trying to whittle that down I'll call it a noble sacrifice & give them a decent burial.  I'll take your adice to heart & run it underclocked though 

The stupid part is that I have the skills & tools to fix the 750W unit, but, as you say, don't want to open it *sigh*

[Pepi]

You try to kill GTX 260?
It is peace of cake: use  12V , put one cable ( + or -) it is irrelevant on any gold contact of PCI express, and with other make contact with all other gold contacts.
That will kill it immediately
That is how I kill some computer parts.
PSU is hard to kill, it shutdown itself  with any voltage irregularities

And for all of those WU, make backup of both BOINC directory regularly  And put it on some other hard disc

I hear you on that! If mine went belly up, I'd have a hard time not opening the case, and digging into it. I'm really sorry your supply died like that. You are right in that these supplies are the best you have ever owned. The 1200 Watt version I have is better than anything I have ever seen.

As far as x39e, or any of the other builds I have run live, I haven't experienced a single problem. These 480's are crunching away like jet engines, and have held up perfectly, even at an extreme overclock. 871 MHz vs 700 Mhz stock.

AS you know I killed the second 1000W PSU with my V8-Xeon. Now in the summer it is not possible to run the machine with 3 Aircooled 470/570, we had some days ago alredy 36 grd celsius outside, and the house where I live has no climatisation. Still a watercooled system and perhaps a 1200W PSU is able running the whole year continuous.
I must wait till late autumn to repair the machine.

My problem is I'm too impatient to wait for an RMA and don't have that many spare parts laying around that I can swap out. If something goes out on me I'm usually in it trying to fix it within an hour. That's about all the time I can manage to keep my hands out of it.

Thanks Heinz,  I thought I was the only one to get those     I may do some further profiling & investigation into the performance of that chirp... The indication of "Error on launch" is enough to say 'something broke here' and I have a couple of ideas that might eliminate those.

How many tasks do you currently run at once on that GPU ? 
Please keep an eye out if it happens again.

I was running two tasks.
At the moment I have no work, several downlods are hunging around...must be patient to get some tasks.

I've only got two errors, both -12s. This one is interesting though  http://setiathome.berkeley.edu/workunit.php?wuid=770546468  Take a look at the one that did complete it. 23 triplets found??
