Topic 196636

Yes, one of my two Nvidia GTX 550 TI in SLI mode, don´t compute tasks to I am just nervous, because I love computing...

The AIDA64 software detect the two Graphic Cards normally, and I go to Nvidia Control Panel and suddenly SLI mode was Turn off ...I turn On again, and reset my computer, and Switch On again Boinc...And now, only one of my graphic cards are computing...

And the second Card doesn't appear in the computer of user...And before yes, appear the two graphic cards...

I need help, because all is aparently normal, but boinc don´t take de second card and SLI mode...

which may have been misconfigured?

Thanks in advance and greetings from Spain :)

Suddenly One of my GPU don´t run e@h...

Hallo Jonatha!
I oberved similar behaviour. I´m running a GTX550Ti and a GT440. The Gt440 stops sometime suddenly crunching and seem to be ok by all tests. But sometimes, after switching off/on it comes back to work and than, even after days of normal working, disapears again. Also I´m for an explanation for this behaviour. But there is one big difference between us. I´m crunching on my GPUs MilkyWay@Home, as for unknown reason tasks of BRP4 are ending up with errorson my rig. If I put this togesther, it seems to me a problem of BOINC. But I tried also older versions of BOINC like 6.12.34 without success.

Hopefully, someone else has usefull hints.

Kind regards and happy crunching
Martin

Thank you very much Martin,

Thank you very much Martin, really i am very worried with that, I am seeing that the 50% of my SLI is turned off...

I also think that is a boinc problem...If the situation remains same, I will try to uninstall and reinstall

Thanks for answer :)

I think something may have

I think something may have gone wrong with the BOINC/SLI relationship. Yesterday I turned my SLI back on to play a game for awhile, and then I just happened to be watching when BOINC resumed afterwards. One of my 570's vanished completely and the other two were running SLOW...like 4 hours projected time to complete a WU instead of 25 minutes.

I shut off SLI and everything snapped back to normal.

It is suposed that BOINC

It is suposed that BOINC shouldnt be affected by the setting about SLI...
But this was not always true and it can change when new drivers appears...

Ussually the best thing it to leave SLI disabled while crunching (you dont need to take out the SLI bridge if there is one) just disable SLI on de nvidia control panel.
Old drivers were mirroring the memory of SLI'ed GPUs which caused long runtimes and sometimes too much memory usage... recent drivers were not affecting CUDA apps or OpenCL when SLI was enabled... but who knows...

Also, there is some issue with the last versions of BOINC in which even identical GPUS are recognized different due to a bug in memory recognition and then BOINC just uses the one that reports more memory... but if this were the case you should see both GPUs in the event log, and one of them should be shown as "(not used)". The workaround if this is the case is to instruct BOINC to use all the GPUs via the cc_config file.

By the way, there was a recent upgrade of Microsoft that signaled as important an upgrade of the video drivers and most computers aout there installed that without even prompting to the user... If your drivers were upgraded by the automatic install that Microsoft does, you may have a lot of weird issues... To solve this, just download the drivers you want to use from the nvidia page and install them using the advanced option and select the "do a clean install" option...

Hallo Horacio, hallo

Hallo Horacio, hallo Jonatan!
Thank you for answering.

First, I don´t use SLI and it happens.
Seconde, in the Eventlog just after startup I find this note (not used).
Third, I did de/reinstall BOINC without effecting this.
Forth, could you, Horacio, please show us what to introduce where into the config file. Sorry, I´m no programmer.

I´ll try this just after sleeping for some hours.

Kind regards and happy crunching
Martin

Please post your Boinc startup messages from the Event Log, the first 20 to 30 lines will do,

me too astro-marwil, now i am

me too astro-marwil, now i am going to sleep that tomorrow I have an exam of Database...

i think that is problem of config file, because my two graphic card are the same, and in the event log, appear one card with:

card0 8381103MB available
card1 1024MB, 687MB available

That's impressive !! :-)

Cheers, Mike.

( edit ) Actually I think the programing error looks to be an integer type/length problem, mixing signed long int versus unsigned int : something like that. If you add 1024 to 8381103 you get real close to a power of two, the deficit being I reckon some MB of used memory.

I have made this letter longer than usual because I lack the time to make it shorter. Blaise Pascal

Something like this is needed

Something like this is needed to use 2 GPUs on Einsten to?
