Unable to allocate X bytes from (x*4) bytes of available device memory

Paradigm

Hi all,

My 2080TI went space invaders and is in the process of being RMA'd, so I'm dusting off my older card, a 1660 Super. However, I'm having an error about it not being able to allocate literally a quarter of its available VRAM.

I've read these errors and people always say it's a lack of VRAM but it makes zero sense here, unless the log is straight up lying.

I have GPU-Z running and Task Manager running. GPU-Z says I'm using ~450mb dedicated vram out of 6GB. Task Manager says 1.4GB. For the sake of argument I'll take the higher, which also aligns roughly with Daz sees. (6GB - 1.2GB = 4.8GB, available RAM is ~4.3, close enough).

Even the WORST CASE  suggests I shouild be able to fit this scene in at least twice, if not three times. 

I'm on Windows 10, latests Nvidia drivers, Daz 4.12, 1660 Super. I've restarted, I've restarted the device from Device Manager. I've even tried the ctrl+alt+windows+B thing.

What gives. Error below. I can provide screenshots if someone doesn't believe me.

Does the available memory decrease earlier in the log, as it allocates space for other things?

I don't see anything about memory between the failing and the initialization of the GPU:

Are you starting DS then loading the scene and hitting render, or starting DS by double-clicking the scene file?

Paradigm

Double clicking the scene file, is one better than the other?

I do, kind of. Interestingly it doesn't include texture or light measurements:

I have two GPUs, a 970 and a 1060. I use my 1060 and my CPU for rendering and my 970 I use for interactive (screenshot attached).

It may be worth trying to open DS, then load the file and render - I doubt it would matter but there's alwats aslight possibility. You might also try unchecking the CPU - a lot of people report that having the CPU both render itself and manage the GPU is slower then using only the GPU.
