Blender Version

Short description of error
When Vram gets exceeded instead of continuing to render with main memory but slower Blender just locks up (crash) and windows asks to close the app.

Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps



Event Timeline

Pretty sure that you have to have enough VRAM for rendering on GPU and normal RAM doesn't add up there.

that holds true for 2.79, master allows the use of system ram since D2056 landed.

VRAM would hit about 1.3 gb before just saying cuda out of memory in last official build with the same scene (think was 2.79b). Downloaded master build from buildbot, mem went to about 2.2 gb in render window stats then just locked up and windows asked to close Bender as had crashed. I can try a blender benchmark to double check, but cant share the scene as commercial.

Sorry forgot to say, I have 12gb main mem, So that isnt the issue
