Hi Pyrus,

thanks for fast reply.

All 4 tasks show credit 0.00, so i believe that credits are only given for validated tasks !

i became aware of the following behavior :

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.

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

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 ?

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 ?

same error here after around 70h runtime

GTX580 with stock clock
Boinc 7.0.25
appl version 1.07 : cufftSafeCall() CUFFT error: 6.

any advise how to prevent ?


7) Message boards : Number crunching : SGS primes ? (Message 53165)
Posted 2744 days ago by Tabaluga

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 ?

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
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.
