Daz not rendering scene/using CPU only/crashing.

Hi,
Ive got a scene with 6 characters, with a (very) simple background, three lights and Daz doesnt want to start rendering. I get there must be a lot to deal with as in the history pane I get the 'VERBOSE' lines when it starts.
'Iray VERBOSE - module:category(IRAY:RENDER): 1.3 IRAY rend stat : Geometry memory consumption: 1.41303 GiB (device 0), 0 B (host)' etc
After about 30mins, I start getting messages about low memory from Windows. Im running;
i7 4790k, Titan X/12gb VRAM, 16gb RAM. Looking at task manager while this is going on and my system in nowhere near topping out.
Thought it might be a driver issue, but updated and no change. Also worth pointing out is that GPUz doesnt even show the GPU taking any load at all (1%) - yes I have GPU selected/CPU deselected in the render pane.
Any thoughts? Surely this shouldnt be an issue? (nothing else is running at the same time also).
Any help is appreciated.

Are ypou sure it's complaining about memory, not disc space?
Fairly sure? the drive has 40gb spare though, is that not enough?
It would help to know the version of Studio and the Nvidia driver versions
In the latest 4.9, deselecting CPU doesn't seem to be acknowledged if the scene can't be rendered into the GPU (or tries and dumps out). D|S will render to the CPU anyway.
Troubleshooting is always best by returning to simple things. Try the scene with just one character (save as to create a new scene, and delete -- don't just hide) the other five characters. If it still doesn't work, it could indicate a more involved driver or other system issue.
40GB remaining may not be enough, depending on the scratch space D|S needs. As needed you can set a different drive.
Finally, it may be obvious to some, but it's worth nothing anyway: when rendering close all other applications. Restart your machine, load your test scene, and see if the problem persists.
Having a similar problem with Toon Forest and two lights. Bypassing GPU (980ti) and using 40G system memory. After 23 minutes of rendering, had 3 iterations. Even my most resource-intensive scene that goes to CPU with that kind of system memory usage shows an iteration every 4-5 seconds.
Customer Service is working on it with me.
Daz 4.9, latest Nvidia drivers (updated yesterday).
Thanks for the reply. Ive been rendering with 1 or 2 characters with no problems. I'll try shifting the drive, though i'd be surprised if 40gb wasnt enough for such a simple image.
There definitely seems to be something up. Ive seen lots of people all saying the same thing. Ive got a great GPU, which I cant utilise because Daz seems to be broken. Its really frustrating (i'll take that back if its a scratch disc issue, but I get no warnings about that).
I doubt it's a hardware issue. I can load a big scene, render it, then restart Studio and load one scene and a couple of lights, and have a render failure. Then immediately restart Studio and load another big scene and render it without problems.
Even if I shut down my computer, go drink a cup of coffee, and restart it. Use Task manager to stop any processes that aren't essential, and it the problem scene still won't render properly.
OK, so this isnt making sense to me. I deleted one of the characters, still not rendering, but no crash. What I dont understand here - is that the 'Memory used' box (which is supposed to be GPU memory) says its nearly topped out (which is crazy), but the GPU load says 1%?
Can anyone explain this - and apologies if I'm being dense.
What does the Memory Used say when you're not rendering? Have you checked that the memory is freeing between renders? (Close any rendered image windows to be sure.)
Well I just tried to remove another character and this time it started to render with the GPU and the 'memory used' box was in the 11k range again, but slightly lower - so I think its reasonable to assume
it needs more VRAM - that seems kind of nuts for a plain floor/wallpapered background, but then Im still new so with complicated clothing on six characters it may be?
Seems strange because ive seen images of people filling entire rooms with characters (well, lots more characters) running much lower PC builds than mine?
Memory used with everything shut is apart from my browser (memory hungry Firefox) is about 800mb.
So - turns out I had forgotten about a lot of clothing that I had hidden in the scene. I deleted them instead of just hiding them - and its now started to render.
Apparently some clothing is quite complex! Still kinda crazy that it tops out a 12gb card.
