I did not commit any fraud, I have only exhausted my 1080Ti graphics card with legal means.
But as I wrote in another post, I said goodbye to this project.

bye bye

Yes, what I don't understand is that we don't get any information from slicker.
The whole project seems very amateurish to me.
I'm retiring a little disappointed.

Now I am flooded with CPU, WUs but none are calculating.
Approximately every 2 minutes 11-40 WUs are downloaded.
I will now disable the CPU option and delete all WUs manually.

After my GPU got WUs again, I requested the WUs for the AMD CPU again.
A lot of WUs have been downloaded, but none are calculating.

strange, one PC can still receive WUs, all others do not receive WUs
well, there are other projects.

my last download was from
10.05.2018 17:25:28 | collatz | Finished download of collatz_sieve_ca6219a6-a399-4190-a47f-255c43689322

I would appreciate it if you could read somewhere, if no more WUs are distributed.

I tried again today to keep my CPU busy.
The WUs have been downloaded, but they are not calculated.
I have an AMD 7 1700 and checked all settings and installed all Visual C++.

does anyone have an idea

Visual C++ 2005,2008,2012,2013,2017 (x64+x86) were already installed
I installed it again in 2017, restarted Boinc, CPU WUs do not calculate

Today I received 16 WUs for the CPU, unfortunately they are not calculated.
Anyone have a suggestion where I should look.

Currently your workunits are taking @650 seconds each, my 1080Ti is doing one unit at a time in @250 seconds each with those codes and the gpu is loaded at 100%.


I don't agree with you.
I calculate three WUs simultaneously and need ~11:50 seconds for each WU, that means 11:50 = 710 sec. / 3 = 236 sec.
Of course, the difference to your 250 sec is small.
I have now activated your configuration and get ~230 sec.
Probably you could test dozens of configurations until you find the optimum.

At the moment I am in 3rd place: https://boinc.thesonntags.com/collatz/top_hosts.php

I have found that with one WU on an Nvidia 1080 Ti the GPU is only ~65-70% busy.
That's why I let 3 WUs run in parallel, so it is also ensured that the pauses are filled in when terminating/starting the WUs.
one WU needs 5:32, three WUs in parallel need 11:12 each
I control the GPU load/temperature with the MSI Afterburner.

have already calculated over 300 without errors, but in BOINCstats I find no credits.
