Hi Miranda822 (team 32),
Your WU (P7809 R7 C192 G16) was added to the stats database on 2013-02-05 10:09:43 for 1894.75 points of credit.

Report closed.

I had this problem also with 7809 (1,151,6) and when I followed these instructions resetting SMP from 4 to 3 I got an unstable machine code and FAH dumped the unit, so probably a bad unit? (Previously successfully completed multiple 7809s on this configuration)

Possibly a bad WU, so far three reports in the database including yours that it failed. There is one successful completion, but it took that folder nearly to the final deadline to complete - 50 of the 55 days. Not enough information in yet to be sure. As for changing the SMP setting, the usual recommendation is to change it between WU's as changing it mid-process can cause one to fail.

It would be interesting to know if the failures are SMP:7 and the success isn't.

The new V7 power options are likely to promote SMP:7 and although it has a lower failure rate than larger prime numbers, I suspect that it's still problematic for some WUs.
