    As already mentioned, keep an eye on texture. Believe it or not, this render nearly maxed out my 1080TI's memory (if I'm reading the numbers correctly), and there are only 2 characters plus some props, a drone, and Mayan Ruins. However, the latter uses instancing, and I deleted parts of it that were out of view. I also used several wound geometry shells, Bloom, and the Cyclops suit for the G3M is HD but I turned HD off because he is barely visible.

    Here are the numbers when I render:

    Iray VERBOSE - module:category(IRAY:RENDER):   1.4   IRAY   rend progr: CUDA device 0 (GeForce GTX 1080 Ti): Processing scene...
    Iray VERBOSE - module:category(IRAY:RENDER):   1.2   IRAY   rend stat : Geometry memory consumption: 591.014 MiB (device 0), 0 B (host)
    Iray VERBOSE - module:category(IRAY:RENDER):   1.2   IRAY   rend stat : Texture memory consumption: 11.3107 GiB (device 0)
    Iray VERBOSE - module:category(IRAY:RENDER):   1.2   IRAY   rend stat : Lights memory consumption: 323.615 MiB (device 0)
    Iray VERBOSE - module:category(IRAY:RENDER):   1.2   IRAY   rend stat : Material measurement memory consumption: 0 B (GPU)
    Iray VERBOSE - module:category(IRAY:RENDER):   1.2   IRAY   rend stat : Materials memory consumption: 976.078 KiB (GPU)

    If that is indeed 11.3107 GB, I don't know why it didn't bounce me to CPU, as the 1080TI only has 11GB VRAM, and it is my only video card so it is used for my monitor as well.

    11.3107GiB is very accurate; it is not the same as 11.3107 GB

    I just looked up GiB on wikipedia and it stands for Gibibyte. It also says 1GiB ≈ 1.074GB, so shouldn't that still exceed my VRAM?

    I'd love to be able to afford 4 GV100 cards since each one has 32Gb of ram, but at around £8000 each I've got no chance of getting those

    ...actually all you need is two and two NVLink bridges (another 900$) which will allow pooling the VRAM to 64 GB.  To link more than two GV100s together you would need an NVLink capable MB which so far as I know are not commercially available

    The Texture Usage amount reported in the log file is UNCOMPRESSED image data.  It isn't the actual amount used on the card.  Do NOT trust that as an accurate number for VRAM texture usage.  IRAY uses texture compression (unless you turn it off) and also probably uses an internal format that isn't nearly as large as uncompressed raw image data.

    This is what I'm thinking of going for Coolermaster cosmos C700P case AMD ryzen threadripper 1900X ROG zenith extreme motherboard 64gb corsair vengeance 2666 ram 11Gb nvidia gtx 1080 ti 11Gb nvidia gtx 1080 ti 11Gb nvidia gtx 1080 ti 11Gb nvidia gtx 1080 ti 4TB seagate hard drive Corsair 1600W power supply. Or swap the Ti's for 2 P5000's

    ...if you are going Ryzen, Windows10 WDDM will reserve about 18% of your VRAM leaving you with 9.1 GB.  I guess you could just dedicate the 1180s to rendering (not hooking any of them up to the display port and using the board's graphics or a lower power GPU to drive the displays) and that would bypass WDDM so you;d have all 11 GB.

    Quadros will allow you to effectively "switch off" Windows WDDM through the drivers, though you will need separate GPU to run the displays.

    I CPU render with 16GB RAM and more than three and sometimes even just 3 figures is enough to crash DAZ Studio with subD of 3 and fibre hair and sometimes even just a lightweight environmental model. I don't think a 16GB card will handle 7 DAZ models unless they are all poly hair & low subD in the viewport & the render. 

    The reason why it crashes at 16GB in CPU mode is that DS adds the entire scene again on top of what is already in your memory. So, if you have an 8GB scene, it will most definitely crash. When you render on GPU, your RAM is just containing the 8GB scene, and the "other " 8GB are shuffelled off to the card's VRAM.

    ...interesting, I have only 12 GB and have successfully rendered a scene that is 8.9 GB in size in memory, on the CPU.  Took bloody long as it dumped to swap mode, but it finished.

    No, it's probably crashes on decompressing of compressed images used as textures and it runs out of memory doing that while it is preparing the scene to render. Of my 16GB RAM only 13GB is available, the rest Windows 10 has a tight grip on and once DAZ Studio tries to take it Windows 10 immediate stops DAZ Studio as taking the reserved memory could crash the OS with far worse consequences than it purposely crashing DAZ Studio.

    ...are you sure W10 WDDM affects physical memory?  I thought that only affected VRAM.  Nonetheless if you have a virtual memory partition, it should dump to that.

    I don't think he is refering to the Windows 10 WDDM "feature" that reserves VRAM, just the large amount of memory that windows of all version grabs to support the running of the system.

    Thanks! Good to know. I re-rendered the scene and the final info in the log file was a fraction of the amount stated above. yes

    ...hmm W7 only takes up about 1 GB on my system ("available memory" is indicated as being around 11 GB out of 12)

    One more reason to stick with it.
