My 4 RTX A4000s are not being utilized by DAZ Studio
BAM! Renders
Posts: 148
I have done everything known to man to try to get DAZ to use my Workstation GPUs instead of my Threadripper to render, and it still will not render with my GPUs.
Drivers are updated. I even went into Nvidia Control Panel to do program settings to Nvidia. And when I finally render, it STILL gives me a Black Screen Render.
Like I heard recently somewhere that newer GPUS, even Workstations especially are not working at all with Daz 4.0+ or better yet until they fix the issue with Iray not recognizing them.
Is this true, cause if this is, I may stop using DAZ for awhile till this is rectified. I can't put so much PRESSURE AND USE on my CPU from DAZ when it is and unoptimized mess of a Software as is...

A4000s are Ampere, same a the 40x0 consumer cards, which are suported - it is Brockwell (50x0) cards that require DS 2025 and can't be supported in DS 4.x.x.x. Exactly which version of DS are you using (Help>About Daz Studio)?
It appears that you cards have 16GB of memory each - while that is a decent chunk it might be running out, depending on scene content and render size - can you render a cube in an otherwise empty scene? Remeber that memory is not poled for rendering, though materials can be shared using nVlink, the scene essentially has to fit into each card independently. What are your settings in the Hardware tab of Render Settings? What are the entries at the end of the log file after you try rendering (Help>Troubleshooting>View Log File)?
The end of the file is showing it ran out of memory, but I don't know why that is happening cause I have all 4 LINKED up in Nvidia Control Panel.
As I said, linked (via nVlink) does not pool memory to give you 64MB - it can pool material memory (which does tend to be the big data chunk for DS renders) but the rest of the scene data has to fit into each card in isolation. Have yoy tried doing a test render with a cube primitive alone? 16GB will be more than enough for that in almost any circumstances so if that fails too the memory shortage messge is probably not reflecting the actual issue.
Ampere is for 30 series, 40 is with Ada Lovelace ~
Four RTX A4000s with NVlink almost bring you zero benefit with Daz Studio specifically... a single RTX 6000 (Ada) will be much better.
As Richard said, the main culprit is usually materials, but with RTX, there's also a massive data structure called the BVH that gets built. That's probably greatly contributing.
The same thing happens to me with my RTX 5060 Ti 16GB graphics card; it only renders with the CPU's graphics. If I disable it and try to use the NVIDIA 5060 Ti graphics card, the screen goes black. Previously, I was working with an NVIDIA 4060 8GB graphics card and it rendered very well. How can I fix this issue?
