Steffen Dünner (SteffenD) added a comment to T53513: Particle Size Weirdness.

After finishing the job that caused me to post this "bug report", I somehow lost sight of this ticket. But on second thought it might actually be worth to re-open it again for the exact reason that ronan mentioned.
Render size and simulation size should both be available but the render size should never affect the simulation. Quite the same as changing the instanced object or group doesn't affect the simulation. You should still be allowed to change render settings after caching a simulation.

Steffen Dünner (SteffenD) added a comment to T53902: Packed Scene with Textures will be rendered wrong.

I don't know it this helps but if I open an image editor and manually set the color space of both the normal and the roughness maps to "Linear" instead of "sRGB" the packed version also renders fine.
Seems to ignore the non-color data setting of the image texture nodes.

OK, I tried to reproduce my problem today with the very latest own build and couldn't reproduce it. I can now slowly but successfully render the benchmark scene on my +10 years old system with only 12GB of RAM and a GTX780 3GB (on Linux Mint that is).
I don't know what fixed it, but at least this is now working properly. Great work! :D

Steffen Dünner (SteffenD) added a comment to rBc621832d3d35: Cycles: CUDA support for rendering scenes that don't fit on GPU..

In my case it's not so easy I guess. I just gave it another try on my 10+ years old dual Xeon system with Linux Mint 18.3 and the very latest master of Blender (own compile).
It's just the Gooseberry benchmark scene switched to use GPU only. I also made sure to only use the GPU (GTX780 3GB) not the CPU or both.
The result is that it starts rendering although the scene would use more than twice the amount of GPU RAM. This is great.
The problem is that the final result is very very dark. I interrupted the rendering but here's a screenshot:

I'm not at home at the moment so I can't help with testing stuff, but the TdrDelay issue affects almost any application using CUDA. Allegorithmic Substance Designer and Painter now even display warnings if they find default values in the registry and strongly advise you to change the settings accordingly.
Here's a helpful article on that https://support.allegorithmic.com/documentation/display/SPDOC/GPU+drivers+crash+with+long+computations
