Daz Studio is not able to access VRAM

About a week ago I noticed that Daz does not use my GPU (1070) for rendering and defaults to the CPU. I know this happens when the GPU does not have enough VRAM to render the scene but it tells me that I only have about 6mb of VRAM, which makes no sense since that video card should have around 4 gigs. Even a completely empty scene uses about 160mb of VRAM and still defaults to CPU. I have the latest drivers and CUDA version installed. The log file simply says that its using the CPU for rendering. Daz studio is detecting the card however, since it shows up in the render settings. So it seems like for some reason it is not able to access the VRAM from the GPU. Does anyone know what might be causing this? I have windows 10 if that matters.

    Are you using DS 4.9.3.166? That's needed to support Pascal cards.

    Yea on DS 4.9.3.166, I should have mentioned that in the original post too.

    Where is DS saying the card has 6MB? Are you sure it isn't saying 6GB, which would be correct?

    I was looking over the log file I saved and I realized I missed this:

    IRAY   rend error: CUDA device 0: cannot get memory statistics (an illegal memory access was encountered)

    IRAY   rend error: CUDA device 0 (GeForce GTX 1070): an illegal memory access was encountered (while de-allocating memory)
