Well, there you go!! Many laptops don't like 100% load. You're not throttling it through the BOINC preferences by any chance are you?

Cheers,
Gary.

Well, I wasn't. I just let it run on only one of the two cores. Now I'm trying to let it use at most 50% of CPU, I'll see what it does.

Did you try a Live-CD Linux yet? It should be a rather recent version tho, so it's guaranteed that it doesn't have this particular kernel bug as well.

Not yet, but after setting

Not yet, but after setting maximal CPU usage to 50%, the problem seems to be gone, if I didn't miss something.

I'll admit to overclocking

I'll admit to overclocking and possible overheating. But here's where it gets odd, and why I wanted to post. I do watercool though, so CPU is never the problem - not the vid card..NB is my concern.

I'd lose approx 25% of my Einstein wu's to Computation Error and get repeated crashes

It's only Einstien that it happens to. That's it. I've run stable for days under all other configurations and projects (for example, I'm on Cosmology right now)..And I got milkyway running away heating things up on the 4870- and I've oc'd that quite a bit too (very, very few computation errors there).

I've got my northbridge under control tempwise - I'm running 3.6 in Windows Vista x64 instead of 3.67 like I was in Linux..(Ubuntu x64)

both OS's would crash on Einstein, and Einstein only.

Phenom II 940BE 780G NB if it helps. Running 8GB at 800 (no OC there either - wanted to rule that out).

Also, if it helps... Astropulse had a tendancy to do it too - why I don't accept those wu's anymore (until I get CUDA card setup or they start using ATI)...

And yes, I'm a throttling crazy baldhead...I live by the preferences...they are everything.....what I aim for perfection for everyday..

Right now it's 4 cores at 90% full steam ahead.....GPU runs at 98% (4870 1 GB 830/1050 clocks) with 85/% stock fan - and the New England temperatures are dropping enough to keep the system cooolll...oh yeah..

92% throttle or above while using the GPU full steam seems dicey. As it is, you can physically see windows flash the memory dumps or something they're so quick and huge...it's nuts..

Just wanted to help Einstein folks...and yes, i vote for an ATI client for Einstein! No, I don't care what work units you send me - both sub-projects are interesting!!

Main projects I've tested to length:
Enigma (runs insanely good on my chip)
Seti@home (enhanced)) - runs fine -
Miklyway@home - cpu units were taking about 80 minutes, on my 4870 they take approx 43 seconds. I want a 5870 and would split resources to different BOINC project definitely..
Cosmology - works fine, seems more stable in Windows though.
Einstein - the crasher! I've narrowed it down finally!

Average I get 30% better benchmarks in Linux. But ATI clients are only in Windows now...boo...that would be cool to get a working client over in linux too..(if you guys wanted to test that too, I'd help).

Right now I'm using 3500 MB actively in RAM with 4 Cosmology wu's running...lol...who said 8GB is overkill...I'd be choking right now and crashing in Vista if I had 4 GB....

In short, is it just the type of equations Einstien and Asrtopulse use compared to the others?? Does it physically harm my poor little CPU?? Abuse it?

See, for me - I was usually running 2 apps at a time and couldn't narrow it down. Now with the GPU - I can run 5 or 3 (eventually finding maximum stability - and now doing one by one*always 4 cores though*) total in a similar configuration - and I was able to deifnitively narrow it down to Einstein being the crasher...did the search..found this thread.

Oh yeah, Preferences in Ubuntu didn't work too well unless you throttled properly anyways..that whole click to not use while computer is in use thing kinda didn't work for me.

That might be your problem (with Einstein). Two of the three still visible erroneous tasks of your windows host finished with "too many exit(0)s" (Can't acquire lockfile). CPU throttling (the BOINC brand) is known to be a cause for that. You could try an external throttling program (TThrottle, ThreadMaster).

I have pretty much just

I have pretty much just gotten started doing this and my problem is einstein. It says it's finished but says computation error. Tried resetting it and everything but keeps coming up to the same problem. only running cpu at 60% could this be the problem?

Yes, possibly. See my post above yours.

I have noticed the tasks

I have noticed the tasks shown on Einstein for my computer that over the period 2 November to 22 November, there are 18 tasks listed. Seven were successful, one is in progress and 10 have computation errors. Of the last seven, one is in progress and the rest have computation error. I don't know what is wrong. Running a quad core with 6 GB Ram.

All tasks I checked showed "Exit status -226 (0xffffffffffffff1e) too many exit(0)s" after

14:03:42 (2112): Can't acquire lockfile (32) - exiting
14:03:42 (2112): Error: The process cannot access the file because it is being used by another process. (0x20)

just like others in this thread.
