Client Error ... computing ... once again

I notice you have two computers listed but I also see the errors you refer to on the 2 cpu box only. You say you changed this for a 2 cpu box a few days ago but it has a results history going back to 31 August still visible?? The results times seem to be virtually identical at all stages. If you had changed your box from a single cpu machine to a dual, I would have expected to see a step change in the results times at the point where you made the change. What is interesting is that up to about 11 September, all results were valid but that after this time all except two are invalid due to abnormal termination of the science app. Did you make some sort of cpu change around Sept 11?

Can you think of any other particular changes that happened around 11 September? Did you make any hardware (eg MB, RAM, etc) change at that point? Did you shift the computer to a different location and maybe something got slightly disturbed or dislodged? Is the machine now in a different temperature environment?

To me, your problem seems to be hardware related so more information on exactly what hardware changes you have made would be appreciated.

Does the new machine have two separate cpus or is it a single HT chip?

I've successfully moved the whole BOINC folder from one machine to another without problems. However they were quite similar in cpu specs. It's really intriguing that a successful result with your old config (Sept 05/Sept 06) took 40,359.25 seconds whilst a successful result with your new config (Sept 13/Sept 14) took 40,451.34 seconds - virtually an identical time???? And yet the cpu specs are so different ....

Also how do you explain why your computer is listed as having been created on Sept 21?? Did you get it a new ID and then merge it with the old one?? Is there perhaps more that you haven't told us yet??

The only advice I can really give you is to start running hardware diagnostics and benchmarks. I really think you have a hardware problem. Have you tried swapping and/or reseating components such as RAM, video, PSU, etc. Have you checked cpu cooling and/or reseated the chip/HSF??

Anyway, best of luck in sorting out the problem.

OK, just a coincidence then that your new HT box can do almost exactly double the results of your previous non-HT box.

The fact that you have been able to get a couple of validated results from the new box leads me to think you have a heat related, intermittent hardware problem. To see if this might be so, are you able to remove the side covers of your case and allow easy access for cool air (a small desk fan would help) to the internal components? See if results would complete successfully under those conditions? Taking off a side cover can make a surprising amount of difference to the internal temperature.
