Just updated the GeForce drivers for my 2060 Super to 436.02.
Now all my Collatz units are failing after 3 seconds:

21/08/2019 09:47:44 | collatz | Computation for task collatz_sieve_dcc7323e-7bbf-4500-b8f7-a2263fc75a62_0 finished

Error: GPU steps do not match CPU steps. Workunit processing aborted.
09:47:40 (2508): called boinc_finish(9999)

*Update*

Removed my optimized config file, and now the units are running. Albeit slower...
Anyone have a working config file for a 2060 Super ??

So, my GTX 1070 system is successfully completing WUs in under 8 minutes.
I have a 'tweaked' config file but NO app_config file.

My GTX 1060 system, on the other hand, flatly refuses to run any Collatz WU if there's any sort of optimized config file
This is what it contains at the moment (copied from your GTX 1050 settings):

verbose=1
kernels_per_reduction=48
threads=9
lut_size=17
sieve_size=27
cache_sieve=1
sleep=0

If the config file is blank then the WUs complete successfully - but they take about 20 minutes.
They always used to finish after 11 - 12 minutes, but I can't seem to find any optimized settings that it's happy with now....

Edit

Scratch that..
I've copied over the GTX 1070 config and I've managed to complete a unit in around 12 minutes.
Let's hope that's sorted now....

Just removed/clean installed the Nvidia software on my GTX 1070 machine - it's made no difference whatsoever:

Seti and Amicable Numbers also use OpenCL and those workunits are completing with no problem....

Just tweaked my Collatz config file and now I have some successful results.

Yeah, I've used DDU many times.....

BOINC seems happy enough that I have a GPU installed:

I started one WU as a test and it failed with the following error:

Incidentally, my other PC (which has a GTX 1070, and which also updated its drivers last night) is merrily chugging through some Seti units at the moment....

GeForce Experience alerted me to the new drivers, and I did a custom installation via that (not a 'clean install' though).

I'm running Win 10 Pro, and have 'driver updates' disabled via Group Policy.

My machine did update the Nvidia drivers to 411.63 tonight - could that be the culprit ???

Well I have had two units validated, and the points credited.
They are taking longer to crunch though - approx 15 mins on a 1070, and around 22 mins on a 1060...
Update
Forgot to edit the config files... Whoops! They've speeded up now...
