Let me state from the outset I'm not a Windows person and so forgive me if I'm missing something obvious.

So here's a bit of a poser. I noticed yesterday that BOINC - running SETI@Home only - my machine outlander had suddenly 'lost' visibility of a graphics card. I have 2 nVidia Titans but only one now seems to be seen as per the highlighted lines below. Originally I had NVIDIA GPU 0 and NVIDIA GPU 1

The system sees the second graphics card, both Piriform Speccy and CPUZ both pick it up and report it as what it is.

I am also running the Lunatics 0.43a apps, so I've done things like:
Remove BOINC
Reinstall BOINC
Reinstall Lunatics (and re-edit the app_info file)

The only thing which has changed is that there was a GEFORCE driver update which happened around the same time I'm currently running 347.25 I'm going to download and re-install the earlier version (if that is possible) and will post if it makes a difference.

In the mean time, if anyone has nay other troubleshooting suggestions I'd be happy to hear them.

Thanks, you wonderful bunch of people you! :-)

Nope, a roll back to 347.09 didn't help, even when it was a 'clean installation' which removes existing drivers first.

Given that the system sees both cards, I am for the moment discounting a hardware issue.

Well I'm out of ideas, anyone else?

Great, NOW I see that the system is saying, for one of the cards:

"Windows has stopped this device because it has reported problems. (Code 43)"

Time for Google...

Just updating in case anyone else has the same issue.

I found this which I am working through now.

You've achieved something it is now reporting only having one 750ti....

Evict the dust bunnies from the psu and both cards. Put one card in and make sure that one is recognised, swap it for the other one, and finally put both cards in.

I would try each card separately, in each slot to confirm if it is the card or slot.

That's because I had a 750ti destined for another machine which I put in it and it and have just noticed it myself. Now it's not using EITHER of the TITANs

Damn it.

OK, I think a proper case of methodical troubleshooting is in order to see if it's a card, a slot or what.

OK, removed the 750ti and the TITAN is seen again.

That is strange in and of itself, I think.

Actually, not - depending on what exactly you saw in the logs.

By default, BOINC will only report and use the 'best' GPU in a system (although it should detect all cards, and mark the lesser one(s) as 'not used').

The GTX 750 Ti has a 'compute capability' of 5.0, against the TITAN's 3.5 - so by BOINC's assessment the newer 750 Ti is the best card (raw speed is also considered, as is usable memory and something else I've forgotten - but the compute capability trumps the others).

So yes, the methodical step-by-step approach is needed to isolate this one, but do pay attention to all information sources - GPU-Z, any speed or fan tuning utility you use, and of course the BOINC startup logs.

Do you have a Monitor connected to the 2nd GPU?

Often with Multi-vendor GPU hosts, the 2nd GPU isn't invisible to Boinc until either a Monitor is connected, or the desktop is extended onto the 2nd GPU,
What is supposed to happen nowadays with Multiple Nvidia GPUs i'm less sure.

I did not know that and indeed in the logs the one working TITAN was marked as 'Not Used'. So that would explain that. Thank you very much.

Is it possible to make BOINC use all GPUs present? A key in one of the many indecipherable xml files perchance?

Also, I have never seen any documentation regarding BOINCs xml files. Does anyone know anything out there describing the keys and their functions? My Google-fu is weak on this.

By default it has NO monitors attached, it's been running headless in my server room with access over VNC pretty much since I got it and has running happily on both cards until the other day.

I'll find out when I get to pulling the cards, which should be later today.

No one mentioned it yet so I'll go ahead and ask.
Does your cc_config.xml contain this setting? <use_all_gpus>1</use_all_gpus>

If they were both working & then stopped I wouldn't imagine this would be the issue, but it never hurts to ask.

What does the Boinc startup say in the Event Log, can you post it please.

All the Docs are in the User manual, you can get to it by going in Boinc Manager: Help>Boinc Help, The user manaual is one of the resources on the left:

So the first line in the logs after a start up is:
05/02/2015 17:48:39 |  | cc_config.xml not found - using defaults

And to be honest I've never seen one so... Time to look into that.

There is indeed (still) only one GPU being detected, I had half expected to see the 2nd being shown as 'Not used', and to have a different amount of memory available,
There is eithier a dead GPU, a dead slot, lackof power to one GPU, or a driver problem,
maybe a new missing GPU Bug when a Monitor is powered down or not connected like with the 295.xx/296.xx drivers.

If the two TITAN cards are identical, might this be an occasion for experimenting with an SLI connector?

In theory, both cards should function independently under BOINC, whether or not the SLI bridge is present, and whether or not SLI is enabled in the driver. But changes in the new driver might have changed that subtly - and may not have been properly reverted when the old driver was re-installed.

OK, update:

It's the card, not the slot or power. Which sucks massively as that was not a cheap card, even though I got it second hand.

Which might explain a lot, it's been crunching SETI@Home pretty much 24/7 for a few days short of a whole year!

Well, now I just need to get cc_config.xml to honour <use_all_gpus> and I can use the TITAN and the 750ti together. It's not quite as good as 2 TITANS but not too shoddy :) But there's the thing, It doesn't seem to be honouring it and with the 750ti in it uses it in favour of the TITAN.

So the obvious next step is: What's going on here? I made the cc_config.xml file by using Advanced>Event Log Diagnostic Flags... to add an element. This created cc_config.xml in the right place and with the right format. Then I hand edited the file to add the <use_all_gpus> key.

Here's what my cc_config.xml looks like:
<cc_config>
    <log_flags>
        <file_xfer>1</file_xfer>

As we can see, the TITAN in slot 0 isn't being used even though cc_config.xml is set to use all.

I really do appreciate the help, people.

It is worth noting, however, that once the cc_confix.xml file has been created, any change to Advanced>Event Log Diagnostic Flags... will overwrite the file and therefore nix any hand edits made to it.

It makes sense but just a heads up to the unwary.

Again, not quite true. Using the log flags GUI will re-write the file in its entirety, true - but it should write the current working state of the file, including any hand edits previously read in and acted on at startup. Mine still has an edited option I first set years ago, which has stayed in place through many, many BOINC version upgrades and (more recently) use of the log flag dialog.

Your cc_config looks OK, including the placement of <use_all_gpus>1</use_all_gpus> - but I may not have had enough coffee yet. You are aware, I presume, that <use_all_gpus> is one of the few flags which requires a full client restart to become active - most of the other options (and all the log flags) can be re-read and become active while BOINC is running.

I was going to suggest making a small benign change to cc_config manually, and verifying that it is reflected properly in the startup log: <sched_op_debug>1</sched_op_debug> logging is a handy one, and can be turned off again if you don't need it.
