Thank you for your report.

Your failure is the only return in our database so far but we will keep checking for other returns.

Posted: **Thu Nov 01, 2012 12:26 pm**

OK. Thank you for your feedback.

Posted: **Thu Nov 01, 2012 3:11 pm**

You should upgrade to 7.2.9. Download on the homepage.

Posted: **Thu Nov 01, 2012 3:16 pm**

Another folder was able to complete the WU for full points:

Hi xxxxxx (team xxxxxx),
Your WU (P5769 R4 C20 G2247) was added to the stats database on 2012-11-01 06:02:42 for 353 points of credit.

I don't want to play beta tester. On the official FAH download page I can only find 7.1.52.

Posted: **Thu Nov 01, 2012 5:48 pm**

7.2.9 is no longer beta. It has been the suggested download from http://folding.stanford.edu/English/HomePage since earlier this week. This was announced in the blog, http://folding.typepad.com/news/2012/10 ... lable.html.

I got BAD_WORK_UNIT a couple times as well (likely on a 57xx project); HOWEVER, it was on a couple of GTX260s (each on different machines) that I'm also getting UNSTABLE_MACHINE, so I'm assuming hardware is the root cause for both. Apparently the factory overclock (and even nVidia stock clocks) fail every several hours; I am currently looking for the highest stable clocks (it's looking like 576/1188/1080/1.125v is it).

Is my assumption correct in that BAD_WORK_UNIT is most likely due to hardware?

Posted: **Fri Nov 02, 2012 10:33 pm**

I'd probably say "very likely" rather than "most likely" (That's slightly less certain, isn't it?).

Traditionally we say if the has been only one failure, it's fair to attribute it to a bad WU. If there have been several, it's hardware. When trying to attribute a cause to statistical events, it's hard to be certain.

"We demand rigidly defined areas of doubt and uncertainty!"

Posted: **Sat Nov 03, 2012 4:05 pm**

I got a couple more BAD_WORK_UNIT errors but I also got more UNSTABLE_MACHINE at sill low clocks (500/1000/1000).
I'm going to start another topic for the latter; I can probable use more eyes on the problem.

Posted: **Sat Nov 03, 2012 5:38 pm**

More eyes won't solve an unstable overclock. Lower the clocks, increase the voltage, increase the airflow. Pick your poison.

Posted: **Sat Nov 03, 2012 5:42 pm**

Also check your RAM

Posted: **Sat Nov 03, 2012 7:55 pm**

You also could have a bad GPU. Some of the GeForce 8000 series had troubles with chips cracking, though I don't remember the details.
