I was using the optimized apps from the lunatics 0.41 installar.
Yesterday i noticed that a wu for the GPU was stuck.
After restarting it ran for a few seconds and a message showed that the graphics driver was not responding an was restored. (or some sort of message)
I deinstalled the lunatics apps and ran seti with the stock apps from yesterday till now.

One of the wu on the gpu had ran for 4 hours and was stuck.
restarted the PC and boinc and waited.
After a few second the message about the gfx driver showed again.

pls someone. Is this a "thing" that has to do with the wu's itself?
Or someone has the same experiance?

the gfx card is showing no defects and i don't have the idea that every wu results in the same "error" .....

the core i7 with radeon HD 5870.
The other runs wu's without using the gpu.

I manualy aborted some wu's on the gpu, including the mentioned wu's
the wu's that went "wrong" :

Did you downclock your card ?
Its only running at 600 MHZ.
Seems to be card/driver issue.

I have just encountered the same problem on my venerable XP machine. The old P4 only feeds the Nvidea GPU and is running APs only atm.

After a few hours the problem went away and now the box is crunching normally.

yes card is downclocked to produce less heat.
But it happens also with "default settings".

For the moment it is crunching, like the one from betreger.

Did you free a CPU core ?
Its important to feed the GPU properly.

Evenso add the following to your mb_cmdline****.txt

-period_iterations_num 40 -sbs 192

Just a tip: When you crunch keep the fan at high speed (use a program like EVGA Precision, MSI AFterburner, etc.) to avoid the excess heat. Excess heat could destroy your GPU in very little time. Normaly the "default fan settings" works fine with games, not for crunching.

Hi Mike,

yep. Raistmer also gave me that tip in the past.
cpu is now runnen on 50% (4 threads) if i cranck it up, it's to max 75% so one core(2 threads) is completely free.

isn't there some sort of debugging mode, or debugging log? where to look if one wu is stuck.

Hi Juan BFB,

i thought the catalyst driver/management software(for my hd5870 oc ed) did a good job managing the fan speed .. i did set it at nearly max speed now, with default clock.

Ok you allready do what i say, use a fan control software (any one, catalyst is one of the software that do that). That´s fine.
You can´t belive how many of the users never do that, that´s why i point you the remainder.
Sure Mike will help you in the rest of the configuration, he is a ATI expert, follow his leads you are in good hands.
