After checking my logs I found one error which occurred the 17th of August 2012. This machine has completed other P8004's without any problems.

Thank you for reporting.

That work unit hasn't been completed by a number of folders. I've marked it bad.

The WU (P8004,R24,C27,G211) has been reported as a bad WU. Note that the list of reported WUs are stopped daily at 8am pacific time.

I seems that every time I get a Project 8004 WU my entire system has freezes at random intervals.

Is there a way to cancel my current WU and not get any more of project 8004?

There is no control at the client level not to get a specific project so your only solution is to permanently remove the SMP or uniprocessor slot.

On a normally running machine, a WU should not cause freezes or lockups. If that is occurring, I would be looking at your OC and/or temps but there could be other HW issues like RAM or a flaky MB.

All projects are not identical. All overclocking benchmarks are not identical.

If your machine is unstable when running the project or benchmark that puts the highest workload on your system (which, according to you is P8004) then your hardware is not stable. Reduce your overclock until your machine is stable under any benchmark or any WU or make other changes to your system so it doesn't crash. From past experience, I'd say you will reduce your total PPD very little, and certainly less than you're going to lose from hangs/crashes.

My machine has never been overclocked and has been folding SMP and GPU for over 2 years.
It has only recently started collecting 8004 WUs which is when this freeze problem started.
Only just last week it had a run of other SMP WUs which always completed without a hitch.
They came after a running a 8004 and freezing a number of times before it finally completed.

So my way out here is to let this SMP WU timeout while doing GPU WUs and hope not to get another 8004 later.

Your ATI HD5850 GPU requires a full CPU core by itself. Have you tried setting your SMP slot in v7 to use only 3 cores?

If you're still using v6 then use the -smp 3 argument.

To add to what has been said on stability, my machines have processed hundreds of the Project 8004 WU's without any issues such as freezing. If you are seeing this with all 8004's, then the issue is with hardware or software on your machine. I would recommend you either follow bollix47's suggestion or try folding with the GPU slot paused while doing these WU's.

Posted: **Sun Oct 14, 2012 8:49 pm**

Recently due to the freezing I have had GPU paused in case it was the cause (new AMD drivers and such) but made no difference.
I suppose it could be a bug in recent windows update.. though I have not seen any problems in other applications/games.

Is there any good way to test all combinations of CPU instructions rather than load testing it on a few?

Every overclocking benchmark makes at attempt to test a representative sampling of CPU instructions but the best option is to run several benchmarks in the hopes that you'll get one that represents the software in question. Stresscpu2 was built around the stressful portion of the actual GROMACS code and comes awfully close to the SMP or Uniprocessor code.

I did check on the status of Project: 8004 (Run 24, Clone 27, Gen 211) and several people have returned it for 0 points so it's what we call a bad WU, not a problem in your machine. That trajectory seems to have been suspended quite some time ago. I don't understand how it got assigned to you recently.

Posted: **Tue Oct 16, 2012 11:21 am**

I have just finished running Stresscpu2 for a day and had no problems.

Also I have never given the exact RCG numbers since I think its a number of different ones but I can say it was not (Run 24, Clone 27, Gen 211).

In this particular forum: "Problems with a specific WU," the conventional recommendation is to start a new topic with the title specifying the particular WU and it's problem. Rum@NoV has done that and I was repying to his original post.

If you have a series of problems then it's a more general issue and it should be preported in one of the other forums.

See Troubleshooting "Bad WUs" at the top of this forum.

Oh.. sorry. I found this topic via the search and did not know about the entire forum just for this stuff. I will get it right next time.
