BOINC Breaking

NightmareXX · 16 Jan 2009 at 22:39

I've had BOINC installed on my new setup for a short while but when booting up the PC, it occasionally finishes the current work unit and exits with a "computation error". The message tab then goes on to say that file <something> absent and then I'm left with no work to do

I've noticed that I only get this error when I take my CPU to 3.4GHz from 3GHz. I've primed it for 30 minutes at 3.4 and had no errors so what else could the problem be? I'm tempted to say Vista 64 myself as that's what I'm running.

Phenom II 940
DFI DK 790FXB M2RSH
Vista business 64 bit
nVidia GTX 280

Well I'm using Vista 64bit with a Q6600 @ 3.6Ghz with no issues. 30 mins of prime is nothing, I generally run for at least 12 hours to prove a stable overclock...

Are you running CUDA drivers, and therefore the client? Could just be VLAR WU's causing the problem? This is a known issue.

I believe it is CUDA myself actually. I'm running Climate Prediction although I wasn't aware that it uses CUDA?

How do I go about finding out if I have it installed? I've got the latest WHQL nVidia drivers but there's nothing listed in programs and features that mentions CUDA.

I didn't think Climate prediction used CUDA client? In BOINC Manager it will say in sevel places, the messages for example (whether CUDA device detected and used) and the WUs are tagged CUDA and show up in the Task List under the Application heading.

Yea, CPDN doesn't use CUDA then, it isn't mentioned anywhere. I had a brief read of the CPDN forums and apparently it can be caused by vista shutting down too quickly and not giving the client a chance to write the data to disk?

BOINC keeps breaking my steam games. Whenever I try to launch one and I've got BOINC running in the background, the game crashes on the intro video with looping sound and the only way out is to end task.

I presume this has something to do with Vista 64?

Hmm I've downgraded to version 6.2.19 64bit although I still have the same problem so it can't be the CUDA support that they introduced.

I started left4dead and waiting for the choppy video to stop (what I thought had crashed) and after a few seconds, the Valve logo video continued as normal without any lag. One thing I did notice is that there was a LOT of hard drive activity when the game was started, more than there usually is.

Theories?

Any news on whether the system is prime stable for significantly longer than 30 minutes? Just leave the thing running overnight, low effort and one less thing to worry about (assuming it passes)
