RAM limit points to how much RAM You allow OctaneRender to use - and that's very much scene dependent and what You are doing with Your system and such. For instance if You allow 10GB to be use out of 32 You have. and Your browser uses 20GB..- most likely You run into issues before You even start rendering.. as preparation of the scene to fil 10GB card and flow over would probably be more than You have in total.. - so again, start looking into resource monitoring apps and see what You have and where You are hitting the wall.
as for headroom, this is simple parameter that controls how much space should be left in VRAM before scene data would start to go to RAM. as pointed before in the other comment, if You are too close to the edge, You might have stability issues, however if Your scene is pushed out of VRAM to RAM too fast, You might loose render speed, so it's a balancing act and it's scene dependent. Sometimes optimizing few textures and keeping less headroom could lead to rendering few times faster, than not optimizing and pushing part of the scene to out of core and then rendering few times slower..
hope it makes sense.

I have had this kind of issue by the past.
Decrease the OpenGL display value to minimum value in Layout and modeler (if launched or better quit modeler) and retry to render.
