I have two computers one running a Xeon 1230 and an Nvidia GTX 1050 Ti, the other an i5 7600 with a GTX 750 Ti. The Xeon machine will not process Blc WU while the other one does. I have reloaded Boinc on the Xeon machine but nothing happened. Any help greatly appreciated as this is just wasting time for the project . TIA.

error -7 Garbled encoded workunit

I'd do a memory test with MemTest86+ first to see if that is causing the data to be garbled.

Another thing I noticed on both of your rigs is that you are allowing Win10 to choose your video drivers (no OpenCL component with them), download the latest drivers from Nvidia.

Cheers.

Thanks Wiggo,
Still no luck. Have checked memory and downloaded latest Nvidia driver on the Xeon machine. Still will not process Blc WU on GPU or CPU. The other machine runs Blc on both CPU and GPU. The app_info file I use is the same for both.
Any other thoughts??
TIA

Did you do a clean install, not just an update?
Just a thought.

SETI@home classic workunits 4,019
SETI@home classic CPU time 34,348 hours

The only other things that I can think of is,

1/ Test the hard drive with the manufacturer's diagnostic software.

2/ Overheating?

3/ Is your antivirus interfering?

Other than that I'm out of ideas.

Cheers.

SETI@home error -7 Garbled encoded workunit
There is a problem with those WUs.

And the ones that run are marked invalid.
You're also running CUDA50, SoG is faster. But still, CUDA shouldn't result in errors and it certainly won't affect CPU work.

I'd suggest running chkdsk and make sure there are no issues with the file system or HDD.
What AV programme are you running? I'd set it to leave the BOINC Data directory untouched.

If they all check OK, I'd suggest detaching from the project, uninstall BOINC, make sure any directories are removed. Reinstall BOINC, reattach to the projects.
Let it run the stock applications for a while. If all is good, rerun Lunatics (i'd suggest the Beta6 installer and make use of the AVX & SoG applications) and see if things stay good.

Somehow you have installed the Older Version 7 Applications on the one machine;
Application version: SETI@home v8
Windows optimized S@H v7 application
https://setiathome.berkeley.edu/result.php?resultid=5780137994
Application version SETI@home v8
setiathome enhanced x41zc, Cuda 5.00 - Detected setiathome_enhanced_v7 task
https://setiathome.berkeley.edu/result.php?resultid=5780206699

You'd probably have better success using Version 8 Applications with Version 8 tasks.

Bingo!

I should've read further down those further into those result outputs.

Your using a very old Lunatics installer there and you can get the latest version (Lunatics 0.45 Beta 6) from here.

Cheers.

Well spotted.

Thanks for your assistance everyone, greatly appreciated.
Have downloaded latest Lunatics and will see how that goes.
Thanks again.

Thanks again.

I'd suggest AVX for the CPU and SoG for the GPU, with a few optimized values. Checkout Wiggos run times for examples of how it performs on hardware similar to your GTX 1050.

Thanks again everyone. The Xeon machine is now processing Blc... WUs.

I see you've opted for the SoG application, it'll do quite a bit more work than the older CUDA application was able to.

There are tweaks you can use to get still more work out of it, but it depends on whether it's a dedicated cruncher or your system for general use as to what values to use.
