You are running a CUDA 3.2 app which is incompatible with Maxwell cards like your 980. You would need to run at least the CUDA 50 app or better still the SoG app. I would run the Lunatics installer again and this time not let it select defaults. You need to make the choice yourself for the SoG app in the menu.
From one of your GPU tasks stderr.txt outputs
setiathome_CUDA: device 1703268 is Maxwell or newer generation, 5.x compute compatibility or higher. Cuda 3.2 or lower doesn't support these.

I reinstalled. How can I check again?

Look at the stderr output of one of your latest reported tasks after you made the change. It doesn't matter if it is validated yet. You should see in the output what application is being used. It should look something like this:
CPU features: FPU TSC PAE CMPXCHG8B APIC SYSENTER MTRR CMOV/CCMP MMX FXSAVE/FXRSTOR SSE SSE2 HT SSE3 SSSE3 FMA3 SSE4.1 SSE4.2 AVX SSE4A XOP FMA4

Windows optimized setiathome_v8 application
Based on Intel, Core 2-optimized v8-nographics V5.13 by Alex Kan
SSE3xj Win32 Build 3584 , Ported by : Raistmer, JDWhale

SETI8 update by Raistmer

OpenCL version by Raistmer, r3584


What you should look for is the application called out as the OpenCL version by Raistmer. Version should be r3557 as installed by the Lunatics installer when choosing the SoG app in the installer menu. I just looked at your latest tasks and I still see the CUDA32 app, so you didn't make a choice again and let the installer install the defaults. You have to select the CUDA50 or the SoG button on the Nvidia MB app select page. The installer defaults to CUDA32 if you make no other choice.

I assume you are referring to this machine hostid=7368589 as it is the only one I see with a GTX 980.

You should add -sbs 1024 -period_iterations_num 10 to your command line text file to speed up a little more.
Make sure its in the same line.
Like this.

-sbs 1024 -period_iterations_num 10 -spike_fft_thresh 4096 -tune 1 64 1 4 -oclfft_tune_gr 256 -oclfft_tune_lr 16 -oclfft_tune_wg 256 -oclfft_tune_ls 512 -oclfft_tune_bn 64 -oclfft_tune_cw 64 (*requires testing)

Simple question fir Mike please.

Is the R3584_SOG for Nvidia on your Mikes World website any faster that the R3557_SOG installed by Lunatics 0.45 Beta 6.

If so are there any timelines for Lunatics installer to use R3584?

As I understand it, no. The r3584 was introduced for the lesser cards improvement. On the faster cards r3557 is supposed to be faster than r3584. I wouldn't expect the r3584 app ever to show up in the Lunatics installer if and when Richard ever decides to write a new installer (slim chance) or some other developer takes on the Lunatics installer project.

Many thanks Keith I'll stick with 3557 then :-)

I know Richard has a new Boinc project support role, but I'd be sorry to see him lose his installer slot.
