It's happened twice so far, but the modeler is crashing every 0.07-8%. I exit out of BOINC to restart. This has happened twice so far. The specific WU in question is: 00en_000025512_0.

First crash @ 0.08% - restart @ 0.07%.
Second crash @ 0.14% - restart @ 0.13%.

XP SP1, Athlon 3000+, 512MB ram, gigs of free disk spac.e

Crash @ 0.15%. appcompat.txt would have been included if the XML content could be displayed here. Restarting @ 0.15%

Hi, Agent Green,

Is your machine overclocked? This CPDN Model is VERY sensitive to overclocking. Models tend to crash early-on on unstable machines. (They may be stable for other applications, but....)

See UK_Nick's links for pointers to appropriate tests to run to determine stability, if overclocked.

Best of luck.

Not in the least. I've never had any problems with any other intensive applications either (predictor / boinc / quake). I'll check the stability testing links, but I find it odd for it to crash so frequently.

I don't know if it's very hot in your place but how hot is your cpu?

The CPU holds steady around 60 deg C. I ran the memtest application over the entirety of last night running all tests for the express purpose of beating the snot out of the RAM, and there was nothing there. I'll run the Pi program suggested if it starts to go nutty when Phase II begins.

LOL, 60 degrees is very hot but should be stable. Strange, you ran some kind of cpu test?

60 degrees is very hot, and CPDN crashes at lower temperatures than other things. Fortunately, this BOINC version doesnt crash the whole system (at least in my experience) like the original did. It may be wise for you to clean any dust out of your heat sink, see if you can get that temperature down a little

Maybe this is another problem but i have experienced the workunit to crash aswell. I noticed it when my system was only running at 50% and cpdn was nowhere to be found in the processes even though BOINC said it was running.

For me i believe it has to do with viewing the graphic, because when i view it it doesn't come up. I just retried this but without luck. I accidentally stopped a cpdn process and it goes straight to reporting an error :S.

My system runs non-overclocked at 42C full load max 50C in summer. Stable Asus board and Intel processor and Kingston RAM. BOINC v2.25 btw.

Do you have an ATI card with recent drivers? If so, BOINC version 4.2x (or above?) will not correctly produce graphics displays. Some Intel graphics accelerators also have problems. Don't use the screensaver, and don't try to display the globe in the visualization. You can download the Advanced Visualization from the left hand column of links to view the model run. Sorry I don't have the link handy for the long thread in the Seti forums about this problem.

Astro:

Don't I know it, I thought I was stable (prime95 stable (12 hours) memtest and super pi stable) but BOINC corrupted my windows and BIOS.

I had some issues on my DFI NF4 with ram timings.

I am sorted now, overclocked and stable with water cooling :)
