So after all the power failures, having to shut the machine down for one thing or another, reboots due to DVD burning etc., BOINC updated to my account this morning around 7 am, and when I arrived home at 5:30 pm, my machine was frozen. Counting the number of completed work units at 14, and my machine completes 4 per hour I'd say it was slightly over 2 hours that the system froze up.

Again, my machine ran fine for a week without boinc. With boinc, 2 days.

I see a pattern here. Anyone else suffering from this problem? Or is it just me.
Thanks.

I was getting system freezes about a month ago on my Q6600... Yes system freezes, NOT BSOD. Swapped out my "high performance" Ballistix PC2-8500 with old faithfull Kingston ValueRam PC2-6400 and been stable even since. The Ballistix ran for about 2 months before starting to fail... this was the 2nd set of the product that failed for me and seems to be a recurring problem from reading reviews.

So, after I posted that, my machine froze twice a day. After being frustrated, and reset button rebooting, I decided that it froze twice a day for three days, don't run boinc again for a couple of days. I restarted it here today, Saturday, so far my machine is freeze free, but I just had it upload to my account just a few minutes ago, some time after midnight. I have the Network connection inside boinc disabled. I turn it on when I want to upload because I am on Satelite internet, and they have caveman style download mb limits.... how archaic, but I digress. Boinc is the culpret. Stable without boinc, unstable with boinc. I would be willing to bet that this machine is frozen again tomorrow morning.

Boinc is the culpret. Stable without boinc, unstable with boinc.

Or it's just a case of the software BOINC runs shows up problems with your hardware.
Not unusual as most other programmes present very little load on a modern system, most of the time the CPU is doing nothing.

...Boinc is the culpret. Stable without boinc, unstable with boinc...

I'd suggest reverting to stock for a while, and/or perhaps 2.4V. If it still freezes I suppose there could be a problem with either the machine or the Boinc installation itself [or configuration settings perhaps?]. If it doesn't freeze anymore then I'd suggest there maybe issues occurring only under sustained load.

[Later: I notice some restarts in some of your WUs I looked at, I think I heard that sometimes suspend or hibernation is known to behave 'funky' on Vista with Boinc, perhaps setting "Leave applications in memory while suspended?" to "Yes" may help]

"Funky" is not necessarily the word I would use for Hibernate mode... more like Flakey, useless, frustrating, I am sure there are more f-words, but I need to keep this clean. My machine has all the hibernation and sleep modes turned off. It is not allowed to go into any of those modes, except to shut down the monitor and the Hdrive. Or in the case of a power failure, shut the whole machine down when the UPS drops below 40%. Which happened there a week or so ago.

My machine has been load tested by the store that sold it to me. I have already replaced the Hdrive and CPU under warranty, maybe it is still my hardware, I actually suspect the motherboard after talking to a friend of mine, but that is going to be a hard one to prove... I think.

However, the machine runs fine with my games, but when Boinc is up and running full out, set at 80%, -> FREEZE. It Freezes always after I walk away, and Boinc is set to screen saver at 4 minutes.

As for reverting, I may have to, but I would rather not, since I am pounding through approx. 50 wu's every 24 hours if not more, depending on freeze downtimes.

If it freezes right after I go to work, it sits here doing nothing for 8 to 10 hours, but otherwise, if it doesn't freeze until later in the day, then it really zips through 'em.

So wo do I revert. Do I have to uninstall the current app, then download the 2.4 and install that? or is there a rollback feature?

Well, setting 'No new tasks' to run the cache dry then doing a project reset would revert to stock and have the bonus of clearing out any project related files that may have gone awry. Running stock for a while, If okay may clarify if there was (or still is) some problem with the Boinc installation itself. Assuming that runs okay:
- then 2.4V could be installed in the normal manner, downloaded from the optimised app links in the sticky thread. If the problem reappears then it sounds like a load issue, if not, then v8 is probably worth a try as the reset may have possibly cleared something. (though be prepared to revert if the load is just to much for your machine, for some as yet undiagnosed reason)

If you are already hardware oriented and completely certain all the drivers etc are up to date then you can probably ignore the next bit:
- I have seen reports in the past of flaky issues with standby etc.. and an overall performance penalty related to device drivers, I'd be checking all these are up to date (whether or not directly related to the issue at hand):
- BIOS ( an update may have been recently been made the shop hasn't looked into )
- motherboard chipset drivers
- Video driver (likely suspect by recent reports)
- Memory integrity with MemTest86+

I appreciate many people feel that this is the shop's job, but is rarely if ever done completely at the store, as it takes many hours. An anecdotal example, in January I ordered a motherboard with express instruction that I needed the latest BIOS installed on the motherboard (as per store policy, and provided the revision number to support the new release CPU), and received two revisions earlier, It worked but was flaky, so I updated immediately and problems were solved.

I can only agree.....if you want something done right, sometimes you just gotta do it yourself. Every computer I ever owned was assembled by me from piece parts....it may be a learning experience, but at least you have nobody to blame but yourself if things go awry....

I really cannot fathom what the problem might be with Bits' computer, but I would lay odds on anything but the SSSE3x app. It is running fine on all 8 of my rigs...the only freezes I have had were due to getting a little overzealous on the OC...and that is not his problem as he is running at stock speed....and the next most notorious problem is cpu cooling, and from what he is reporting that is not a problem either....
I would bet on the Boinc installation maybe fighting with Vista....from what I have read in the forums, a complete reinstall in a dedicated folder might be the answer...

A couple of footnotes on that:

1. After running the cache dry, be sure to select the project and click the Update button to report the completed work.

2. You have to remove the app_info.xml file manually and do a BOINC exit/restart before doing the project reset, otherwise BOINC will preserve the files listed in the app_info.xml and the host will continue running the optimized app.

I'm sorry if this has already been suggested and tried but, have you turned off you throttleing? I used to throttle my quads but they always locked up or else corrupted packets. I dissabled throttleing and all was cleared up.

Hope this helps.

Ok, this one I don't know how to do. Where are the throttle controls? In the bios? if so, is that what ASUS calls it?

If Throttling is the same as OC, my cpu is factory set at 2.4, only the video cards are OC'd and again, factory.

I have found new video drivers, the last ones installed were March 2008, the newest ones are June 23, 2008 from NVIDIA, evga has May 12, 2008 drivers. I installed the June drivers tonight. I suspect it won't make a difference, but we'll see, I just may be surprised.

The BIOS is up to date, and all the chipset drivers are current. They were all released in Oct 2007, and I have installed those drivers so many times, I know them off by heart.

In BIOS, make sure that Speedstep is disabled to prevent throttling.

I was right, this morning, FROZEN, with the new video drivers, but this time, it didn't even get a chance to turn off the screen saver. When I turned the monitor on, the screen saver icon for BOINC was sitting there. That means it froze within the first 3 minutes after kicking in. It is only on for 5 minutes before it shuts down the monitor.

Was this with the stock seti application?

Did you try disabling your screensaver? I'm assuming with a quad you have a L.C.D. monitor and a screensaver is just using power. The L.C.D. monitor isn't subject to burn in as the C.R.T. monitors were. Mine is set to turn off after 5 minutes and the screensaver is turned off.

Sutaru did a good post in New Optimized Apps Links -- READ ONLY THREAD about SSE versions. I'll just add a few comments here to clarify the current situation.

The "Windows 32 bit AK v8.0 SSE (Pentium 3)" version will run on any SSE capable host, but did not give a speed increase on AMD systems.

On a 600 MHz. Coppermine P3, it gave speed boosts of about 18% at VLAR and VHAR, about 35% for mid-range work. On a Tualatin P3 the boosts were slightly less.

Crunch3r's "2.4V_Windows_x32_SSE_FFTW" does seem best on AMD systems with no more than SSE. It is particularly effective on a Duron system with only 64 KiB of L2. It should also run on any SSE capable host, and I have a suspicion that it might also be best on a Celeron P3 with 128 KiB L2. If I had such a system, I'd certainly try both.

                                                                 Joe

I have a question about optimizing in Linux using the optimizer for SSSE3 Intel Processors. I have an unclocked system Linux 2.6.24-19-generic running Ubuntu 8.04 with a GenuineIntel Intel(R) Core(TM)2 Duo CPU E6550 @ 2.33GHz [Family 6 Model 15 Stepping 11] that is SSSE3 compliant with 1997.14 MB of RAM.

Is this system compatible with this latest optimizer? If I run SETI@Home with this system it won't burn out the CPU or anything? Is there anything else I should be concerned about this system if I do run it ?

Thanks for your time, it is really appreciated.

Yes, the Linux 32 bit AK v8.0 SSSE3x or the Linux 64 bit AK v8.0 SSSE3x will work with your system (You did not tell, if you have a 32bit or a 64bit linux installed).
No, optimized SETI@home applications should not harm your system, as long as you keep it in good shape. Meaning, you're cleaning air in- and out-takes of the system on a regular basis, make sure fans and powersourceunit work within normal parameters and prevent mechanical misuse.

Uhm...Thank you thank you thank you!
Im really liking this app. My RAC went from 730 to over 1300, and Im an AMD dual core on XP Pro.

Im Using the AK_V8.0 Win32_SSE3 App

So once again, thank you.
