Hello, just added a new workstation with an nvidia card and the current driver for it (GTX 750 and 335.23). On the server status page over 400 long run work units and 800 short run work units are reported as available.

When I try to get no work, the report via BOINC is no work available.

Checking your computers I don't see the GTX750, but one PC has work done and has work in progress, so that works. Perhaps you need to check the settings on the other PC if it may run on the GPU.

Greetings from TJ

Thanks for the response.

Last night I tried a full uninstall and resinstall of BOINC on that system -- including first deleting all traces of of BOINC in the Program Data directory.

The reinstall was clean. Didn't solve the problem.

The computer which gets GPUGrid GPU workunits is running Windows 7 64 bit,
a GT640 video card, BOINC 7.2.42, nvidea driver 335.23.

The computer which isn't getting GPUGrid GPU workunits is running Windows 7 64 bit, a GTX650 video card, BOINC 7.2.42, nvidea driver 335.23.

So the only variable I can see is the GT640 versus the GTX650.

I can download and process GPU work units from Prime Grid, and Collatz with either system. So the other variable if you will is GPUGrid.

Hopefully someone will be able to enlighten here.

Hi,
Is that computer set to the same location profile in GPUgrids preferences as the one that is working?
...regards

Yes -- actually simply set to default -- I haven't configured separate groups.

I have a computer set to drop off due to it no longer running BOINC -- it was getting work with a very similar configuration (earlier sub versions of BOINC and the Nvidea driver, but also a GTX-650.

Could you copy & paste the first 30 or so lines of the Boinc event log just after it starts.

Here you go -- this is from my restart a few minutes ago:

Two things I can think off.
1 You have had to many error lately, then you are banned for new work for 24 hours. I don't know the message about that in BOINC as I have never seen it. I don't think this is the case with your PC.
2 You have other work running on the GPU that has a long time to finish. You are not getting new work then. But normally the message is then "no new work, not needed".

Have you a CPU core free?

Greetings from TJ

Thanks for the follow up. I am doing other BOINC work on that system, but I'd get a not needed in that situation. Been there done that.

There are available CPU -- currently running either POEM or PrimeGrid. Current PrimeGrid is using the GPU as it had no problem with this configuration.

As to errors and lockout -- don't think this applies here. After all, it isn't error messages, just a curious 'no work sent'.

Now I have seen that before with other applications on BOINC, but in this case I encountered this with a fresh clean install of BOINC and no other project attached to begin with.

For some reason, the GPU is being reported as compute capability 1.1, which I suspect is why it's not getting work. I would try an earlier driver.
What does your 640 report as?

Regarding the GTX 650 erroneously reporting as Compute Capability 1.1 ....
... are we looking at a BOINC bug here, or an NVIDIA bug? Is there any way to tell?

OK -- thanks, I will try a driver uninstall, then install an older driver -- say from about 6 months ago.

I'll report back tomorrow.

I don't think it's BOINC. BOINC just calls the functions in an NVidia DLL, and reports on the answers it gets. Look at this combo:

Even a three year old version of BOINC can report CC 5.0 accurately - though it goes on to be completely confused about GFLOPs peak (that would be shown as 1640 by an alpha BOINC that has the correct cores per SM for a Maxwell). BarryAZ is using BOINC v7.2.42 - we'd know all about it if that version had a bug as gross as that.

I don't know which other GPU tools report compute capability, but I'm sure somebody here will.

@ BarryAZ - I don't think the age of the driver matters: just choose one certified for your card, and go through the 'clean install' procedure to remove any stray components from some older installation.

Folks, thanks for all the suggestions -- no joy here.

I have done several full uninstall/reinstall cycles of BOINC and various different Nvidea drivers. All yield precisely the same frustrating result. For the edification of the collective here I am including the last of these efforts:

For some reason, it seems that GPUGrid or Nvidea doesn't like this particular card. Curiously, other BOINC applications will feed GPU work to this card -- Collatz, MooWrap, PrimeGrid. I suspect that POEM, once they get their application running will work as well.

I don't know that there is any other 'monkey/keyboard/shakespeer tests I can do to get this to work at this point, so, absent a silver bullet, I think I will desist for now from the 'try this, try that, sequence for now. I will set this system up to process GPU work units for one or two of the other projects which doesn't have this curious problem.

First of all, the issue of "not getting work here" definitely feels like it is the result of that erroneous 1.1 compute capability.

For reference, I have posted your problem to NVIDIA's 337.50 driver feedback thread.
https://forums.geforce.com/default/topic/720880/geforce-drivers/official-nvidia-337-50-beta-performance-display-driver-feedback-thread-4-7-14-/post/4206175/#4206175

I'll chime back in if I get a reply from NVIDIA. An experienced user did reply saying he thought the drivers were erroneously reporting OpenCL capability, instead of Compute capability, for your GPU. But we don't know for sure.

Like I said, if I hear more, I'll reply back.

OK -- so for some reason the card is showing a compute capability of 1 instead of 3.

I will research further

Actually Compute Capability 1.1 - still clearly something is amiss.

I posted a query on the Nvidea boards.

I purchased the card via Ebay, card looks new, and reports properly at the bios level as a GTX250. Nvidea drivers believe it to be a GTX250. It may be simply a well made knockoff (no specific manufacturing info on the card to speak of).

I am not sure what performance benchmark software I could download and use to verify overall performance.

For what its worth, Windows 7 shows 5.7 for graphics and 6.4 for gaming graphics

My error(I do not see an edit function here for messages).

The card is a GTX-650 with 2G of DDR3 memory.

Something is clearly not right with the card - I just checked my other system, which runs properly, with the GT-640 - in theory a lower performance card, which does run GPUGrid -- the Windows ratings are 6.6/6.6 compared to the 5.7/5.9 for this GTX-650,

Guess the card was too good a deal <sigh>

We're trying to solve it. We don't know the cause just yet. ManuelG from NVIDIA is trying to reproduce the issue right now.

It'd really help if you could run GPU Caps Viewer, and tell us the value it shows for compute capability, on that GTX 650.

Also, perhaps you could install GPU-Z, and report to us the BIOS Version, and the Subvendor. GPU-Z can also be used to extract the BIOS (there's a button that shows a microchip with a green arrow), which is something ManuelG might want later.

Caps viewer confirms the 1.1 value. I suspect the card is something of a 'good looking knockoff' here.

I sort of doubt there is any way to 'fix' this -- but could be wrong.

By the way, getting that Caps viewer file lit up my ESET AV report.

I've started a back and forth with the folks at nvidia. I'll report back here. Seriously, I suspect that I'll end up replacing that card with something I purchase direct from NewEgg -- fully 'vetted' as it were.

After back and forth with Nvidia, we've reached the conclusion that this is a well manufactured knock off card.

It looks well built. The system BIOS and diagnostic software report it to be a GTX-650. But it clearly is not in terms of performance (not just the lack of getting GPU work here, also the poor performance in processing GPU work from other projects.

I've referred the problem back to the Ebay seller for resolution.

Any chance we could get a screenshot of GPU-Z's "Graphics Card" tab, as well as a photo of the GPU itself, just to satisfy our curiosity? :)

[Sorry for your grief, if it is a knockoff]

It's pretty apparent the card was a knock-off (and apparently a pretty good imitation as it 'fooled' the system BIOS. When I protested this to the seller on EBay -- I had two options -- return for a full refund (with me paying shipping), or taking a 25% credit driving my out of pocket down to about $40.

I chose the latter as 'return for credit' is a bit of a hassle with shipping and the like, and the card is functional at about a GT-210 level.

I replaced the card with a new Asus GTX-650 with 1Gb of memory and it was recognized properly, I've already completed on work unit with it.

I'd note I worked with the Nvidia tech support folks -- one or two emails back and for for each of several days before confirming the card as a knockoff.

I will take a photo of the card at some point and post it. Aside from the performance issue and the confirmation of 1.1 versus 3.0 for computing capability, along with the lower Win 7 performance numbers, the other key here is there is no manufacturing information on the card. There is the 'Nvidia' name and logo on the fan. On the back of the card, the 'manufacturing' sticker doesn't mention a manufacturer -- just GeForceGTX650Graphic, 2G, DDR3.

I'd note the Asus card I now have has 1G, DDR5 memory.

This is a very edifying story.
