For some reason I can't seem to get any GPU tasks from any of my projects. From what I can tell GPU Grid and Collatz have run into technical issues so I tried Prime Grid. No luck at all. So now I am wondering if there isn't something wrong on my end. I have updated to the latest version of Boinc and still have the config set up to allow GPU's. Am I missing something or has something changed while I was away?

Still running Win 8.1. Nothing has changed in my system from when I last ran Boinc stuff about a year ago. I will look into the driver issue and see if that is the problem.
 

I still have the Visual C++ Redistributable Packages for Visual Studio 2013 already installed. I was running the latest Nvidia drivers so I'm hoping that is the issue. Downloading 391.35 now.
 
Going to get GPU-Z again and run it. Will post an update when that is done.
 
Update: Ran GPU-Z and the Cuda box is unchecked. Guessing that is the driver issue you mentioned?
 
 

OK, I did the DDU and a clean install of both 390.65 and 391.35. Neither one worked. I still get the missing check mark for Cuda in GPU-Z. Any more ideas?

Is this a New Card?
Have you ran any benchmarks to test the card out?
Did you Remove the NVIDIA Stuff from Windows "Programs and Features" this should be done first.
Then Use DDU and tell it to reboot in Safe Mode.
Run DDU and remove and Restart your Computer and then Install Only the Graphics Driver and PhysX Driver.
Remember to Run as Administrator on all of the Processes.
Is your Card installed in the X16 PCIe Slot next to the CPU Socket?
x8 1.1 seems odd.
Are you running 64 Bit or 32 Bit OS of Window 8.1?
What CPU and Motherboard is this?
If it has it is the Motherboard Video Disabled?
 
Looking now at https://sourceforge.net/projects/cuda-z/files/cuda-z/0.10/CUDA-Z-0.10.251-64bit.exe/download
 
 
Above what most user do I also delete the below Keys after I remove the Drivers and Run DDU in Safe Mode. (No Network)
I do not restart after Running DDU I Delete the Below Keys and then Restart, it will Error on them but that is ok it will still delete the card Info.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\Video
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Video

Not a new card. I have been running it since Feb. of 2017.
Yes, removed Nvidia files from programs and features.
Yes, restarted in safe mode and removed the network cable, then ran DDU.
Installed graphics and physx only.
Yes, Admin.
64 bit Win 8.1
Yes in first slot. However there is an old GTX 680, in the second slot, I used to run secondary projects. Suspect the motherboard is splitting the x16 for this.
Asus P8Z77-V LK LGA 1155 Intel Z77
Intel Core i5-3570K Ivy Bridge Quad-Core 3.4GHz (3.8GHz Turbo) LGA 1155 77W
Yes, video on motherboard is disabled.
 

There are a few things that could cause gpu-z not to show cuda is supported...
 
#1 The cuda gpus setting inside the nvidia control panel is set to none instead of all. Changing the setting to none then clicking apply, and changing the setting back to all then clicking apply may resolve the issue for you, so make sure you give that a try as well.

 
#2 GPU-Z may not be reading it correctly. Try a older version of gpu-z.
 
#3 Your os has a problem. Doing a clean install of the os will fix the issue.

nice documentation bcavnaugh

Don't you need C++ 10, 13 and 15 both 32 and 64bit? You would think the newest one covers it, but no, thats too easy.
 
If more than one GPU is there a setting in a config file to use all GPUs?

970M -v- 1080 Ti

Also why I do not Fold or Crunch on my Laptop
 

 
 
 
Nice Little Benchmark Tool
The Desktop Version allows you to Select OpenCL or CUDA for Benchmarking.

Nothing seems to fix the issue. I tried Enigma and got nothing.
 
I am wondering if I don't need to totally remove Boinc and all the associated files and start over from scratch. I can't find anything that is wrong in the config files. Its like something didn't update right from around when I took a break.
 
At this point I'm going to keep on with just CPU tasks until the Seti event is over and then shut it all down to remove the old GTX 680 and do a fresh install of Boinc.

What does your event log say from a clean startup of BOINC? In another thread you mentioned upgraded your version of BOINC. Did you install it as a service by chance?

Frankly I have put solving this on hold atm. Going to be busy with doctor and hospital visits for the next week or so.
 
To catch up on questions being asked.
 
No I did not install Boinc as a service.
My config uses those two entries.
My Collatz folder is empty. No XML files or any files for that mater. Yes, I did reset Collatz with no luck.
No I do not use BAM.
 
Here is the log after start up.

This is weird. We had a heck of a lightning storm Friday night. It knocked out our internet for the weekend. Net came back up early Monday morning. I rebooted the system, after setting up the modem and letting it go through its restart sequence, and now I can run OpenCL GPU tasks. The odd part is I have rebooted the system dozens of times since I noticed I had a crunching GPU problem. I had also rebooted the modem at least twice in that time. I don't think the modem had anything to do with it but figured I would toss it out there as new info.
 
Now to figure out the Cuda issue.... sigh...

bcavnaugh

I restart my Internet Modem as lease once ever three or four weeks to include all my Routers and Switches.

I tend to do it once a month, if not more often if needed. I don't see what the modem had anything to do with it since it had been reset at least twice since this GPU thing came up. Guess its one of those things I won't worry too much about and just be happy my GPU is working for OpenCL.
 

+1  back to basics is always helpful - after looking too deep for a complex answer
