Does anyone have any ideas please - I have a laptop with a Quadro K3100M, which has the latest drivers and meets the specs for CUDA for RC, but I get a message saying ‘No Sufficient CUDA Capable Devices Found’.
GPU-Z shows that there is only the K3100M GPU on the laptop, there is no Intel or other GPU available.
I’ve tried reinstalling the latest (and older) NVidia drivers (both the new features ones and the enterprise ones) and also reinstalling RC but still the the same message when trying to select the GPU under Reconstruction / Settings / Image Depth Map Calculation.
I did install an early beta of RC (before laser scanners were supported) on the same laptop about 3 years ago, could there be something left behind in the registry that is causing the problem?
Any ideas on what I can do (apart from reinstalling Windows - its Win 8.1) please?
Thanks,
Jonnie
well, provided that you have done it correctly:
do other programs using the GPU function well? had RC run well (without this error) with this hardware configuration any time before?
this could be a Windows issue though (I would upgrade if possible, or try to uninstall Windows updates, if all else fails, reinstall Windows), sometimes a power supply cannot provide enough power for the graphics card, or there are other connection problems, I would also scan for registry issues and fix them automatically with CCleaner
and how about the advice in the last post here? https://support.capturingreality.com/hc/en-us/community/posts/115001361392-your-computer-does-not-have-an-nvidia-graphics-card
contacting NVIDIA support could help, as well
Hello Lucia,
Thanks for your message, I’ve contacted NVidia, who were helpful.
I tried using DDU to completely uninstall the driver and clear any registry settings, but that didnt work, and I’ve come to the conclusion that Windows is almost certainly the problem. Other similar problems (similar in that nobody can get to the root cause) I’ve had recently have been fixed by reinstalling Windows, but this is obviously a pain in the backside and it’ll take about 2 days to rebuild the laptop afterwards, so I’d rather avoid it.
I’ll try CCleaner to check the Registry, thanks for that.
Then I’m just awaiting any update to the BIOS and chipset drivers (but I dont think there are any), and then I’ll probably reinstall Windows. If that doesnt work, then I will upgrade to from Win 8.1 to Win 10.
I will let you know if a fresh Windows install fixed it in due course.
Thanks,
Jonnie
No BIOS or chipset updates available for my laptop since 2015 (ie when it was new), but tech support suggested that I reinstall the original Clevo-edited GPU driver (348.nn).
This brought back the CUDA abilities!
I also changed an option in the BIOS to do with the GPU - it allows the GPU to have more power and therefore better performance, but at the expense of slower CPU, but I think it also requires some Clevo overclocking software - anyway, the CPU is still running at 4.4 GHz, as it was before.
With CUDA back, and knowing that I still had CUDA working about 6 months ago, I then did a custom install of the graphics driver only from a more recent version of the GPU drivers - 388.16 - and that also allows CUDA to work properly.
So, it looks like something changed in the NVidia drivers in the past six months that disabled CUDA for this laptop.
Hope this is helpful for somebody else.
it will sure be, thank you
