If it's power, try pulling one of the 460s and see if the problem goes away.

Here is an update:

I updated BIOS - no go - after update and sanity check on settings (basically stock) still
blowing out GPU work units.

Popped the side panel off and ripped out the 2nd 460 (it was the 768 card) left the 1G card
there. This seems to have stopped blowing GPU work units - at this point perhaps it is a
bad 460? I have a GTX 550 TI NIB that I could swap this 460 out with - have to do
some research but I think the 550TI has an edge on the 460...

As for the dust balls - not to bad on the inside:


I'll let this run for a day and perhaps all ya all can help me check the work units ?
Thanks again for the tips etc.

actually that is pretty bad. that's a pretty thick layer of dust on your PSU. Time to turn off the machine and clean it out thoroughly

Corrects to my last update.

So after I watched the GPU for a bit - it stared blowing right thru them.
Swapped out the GTX460 1G for the GTX460 768 and observed the same behavior.
(now at a total loss) (2 cards bad?)

As it stands now - I replaced BOTH cards with a brand new 550TI I had laying around.
Have not seen a GPU task yet for that card. Will keep my eye on it.

(and it is well cleaned out - dust be gone)

So I stepped away from the console with much frustration - but about a month later I am back

All drivers up to date etc.
I reset and detached from SETI
deleted the BOINC data folder
rebooted
re-installed BOINC
re-attahced to SETI project

Still blowing out work units - show all running for 01:55:49
and early reports show results are invalid...

I am about to toss in the towel - anybody have ANY last suggestions?

Nothing comes to mind.

I had a look at your initial post, and what you've got appears similar to me (in terms of hardware, OS & settings).

I've got an i7 2600 with a GTX 560Ti, Win7, 320.18 NVidia driver, running Lunatics_x41zc_win32_cuda42.exe & AKv8c_Bb_r1846_winx86_AVXx.exe for the CPU.

On my E6600 with a GTX 460 it's got Vista, 320.18 NVidia driver & Lunatics CUDA 50 app and the SSSE3 app for the CPU.
No issues with returned work on either.

Have you checked voltage to the card? A long shot im sure, but hey you never know.

Is your system showing any problems apart from seti?

I would try running memory, cpu, and gpu stress tests.

Memory: Windows has a built-in memory test you can run on start-up (F8 on Win 7 boot). Let that go for a long time, like hours and hours.

CPU: SuperPi is sometimes used http://www.overclockers.com/forums/showthread.php?t=372246

GPU: I have used TechPowerup GPUTool. Most of the things on it don't work yet, it's pre-alpha even, but the "Test for stability" button works. Some overclockers are using it. http://www.techpowerup.com/downloads/1383/gputool-community-technology-preview-1/

Monitor the temps on your cpu, motherboard (southbridge), and gpu while you do all this.
