Hi Pyrus,
thanks for fast reply.
All 4 tasks show credit 0.00, so i believe that credits are only given for validated tasks !

Hello,
i became aware of the following behavior :
pls see this entries

4 tasks that can't be validated, thats hard !
I would suggest that these tasks were validated by core team or at least that the user get credits for these tasks.
Otherwise lots of computing hours were totally lost.

GTX 580 crashing all CuDA tasks after some seconds

thx for the tips and hints :-)
it looks the card is damaged, any WU prime, GPUgrid, seti fails after around 1 min
lowering the GPU clock to 500MHz, memory to 1000MHz does not solve the problem :-(
i will sent this card back and get a new one
hopefully the problem is solved

the clock reported is the shader clock
this was a downclock test with gpu clock 500MHZ
you can see the stock clock 1566MHz shader 783MHZ GPU clock in this WU
http://www.primegrid.com/result.php?resultid=371731984
i don't belive that you can clock the GPU with double speed without
dry ice or liquid nitrogen ;-)
Furmark ok
GPU caps viewer shows some artefacts in only one test
(GL2.1 HDS, DoF and RadialBlur)
i also tried a fresh installation with win 7 x64, boinc 7.0.25 and 285 driver
same results

Hi @all,
i got a new GTX 580, it worked fine with 285.58 driver on win XP SP3 x86
Boinc 7.0.25
Gainward GTX 580 with stock clocks
GPU temperature around 75 degree celsius with full load, should be ok ?
http://www.primegrid.com/results.php?hostid=234645
after some days of crunching the card suddenly crashed a world record task
after that all tasks on CuDA crashes.
Tried to update on 301.24 driver, but same :-(
No trouble so far while browsing
Is there any programm / tool available to test the hardware of this card.
My fear is that the card did not tolerate crunching hard 24x7 !
Any hint ?

SGS primes ?
(Message 53165)
Posted 4060 days ago by Tabaluga
Hi@all,
i just recongnized that i found 2 SGS primes during SG challenge
Got no mail about that ?
Are they not worth an email ?
first : 4602694336005*2^666669-1
second : 34157886059955*2^666666-1
Can anyone help me understand why they are reported in my statistics, but i never received an email finding them ?
Are they to small or is this reporting wrong ?
regards
Tabaluga

Hello,
looks like the 32bit and 64 bit boxes are getting WU differnt.
My 32bit box everything fine, my 64 bit box is out of work for more than 6h
now.
Also the upload for 64 bit is different, within a time frame of less than 10sec
the 32bit box is able to sent WU results, the 64 bit box isn't.
Any ideas what happens ?

next wu failed with same error code
core 675
shader 1350
memory 1800
so now i took back core/shader to normal 715/1430
and memory to 1750
will come back with next result.

yes, correct never used app_info
the out of sync problem is solved :
restarting boinc did not help, but just detach from primegrid and
reattach solved it.
