Well, clocking down in Afterburner doesn't help either. Here for example an error I'm getting with driver 457.30.
Really every driver has a different error. Mostly CUDA error code 999.
I will try that stress test with OCCT and look what will be the result.
Both Iray and the drivers are made by nVidia, not Daz. Still, soem people have been able to use - and post benchmarks for - 3090 cards so your experience is not universal.
After testing my GPU with 3D Mark and OCCT, it's now clear. The problem are not my cards, not my PSU, but Daz studio and Iray. The "MSI RTX 3090 Gaming X Trio" is NOT FULLY SUPPORTED by Iray yet! Works extremely unstable with rendering results like this: https://i.postimg.cc/j21SssDF/2.png
I'd really like to ask the Daz devs and Nvidia to finally make also these powerful 3090s work properly with Iray!
I'm not helping, but it's still odd that it doesn't work. The aftermarkets are supposed to be the same chipset as the FE with only the power delivery, clock boosts, packaging and cooling being different (supposidely superior). Drivers are supposed to be the same... unless NVidia has actually started introducing differences in drivers?
I recall there were people who had to back off on their OC to get Iray working in the releases thread, even if the OC was otherwise stable in gaming and benchmarks. Kinda why I got the FE in the first place. But you've already checked that so I dunno.
May help if you could test other Iray products (like Character Creator or Reallusion's standalone Iray viewer) to see if the problem is with DAZ or NVidia/Iray, but I don't know of any free ones. I think the viewer that comes with the Iray SDK is also licensed. Do your cards render fine in Blender Cycles? You may need to go in to the settings and enable all the NVidia features (Optix or whatever they're calling it these days).
I can't find that "optix" in the settings anymore. And I never worked with any other program than DS. And I lost so much time because of that render issue and I need to continue working somehow, even without rendering. I don't have time to learn how to work with blender at the moment.
I hope there will be an 4.15 and Nvdia driver update soon. Maybe it will be fixed. If it will be the same, I will try it with Octane even though I also don't know anything about it and have 0 experience with it.
Yeah, Octane was going to be my next suggestion. If you can test it, at least you can confirm there's nothing wrong with your cards in heavy render workloads. But maybe you know that already and this is just NVidia doing fishy things under the hood again.
You haven't given specifications of your computer, what does it have inside?
Mainboard: Gigabyte X399 Xtreme
GPU: 2 x MSI RTX 3090 Gaming X Trio
CPU: AMD Threadripper 1920X
RAM: 128 GB Corsair DDR4 2666 mhz
PSU: Seasonic 1300W Prime 80 Plus Platinum
Every PCIe slot of the GPU has an own cable. I didn't use the Y slots.
I moved to the 4.15.02 beta and I'm still having isues. This is why it would be great if they (like Adobe, for example) allowed you to roll-back easily to another version of the software.
@Rafa20 - I have an AMD CPU (R5 3600x) which makes me wonder if it's related to having both (?). I'd be interested in seeing if other 3090 owners with AMD CPUs are having issues.
OK and how many of them used a MSI 3090 Gaming X Trio? It might be working with the weakest cards. For example the Founders Edition. But it seems that not every 3090 card is the same and works the same way with DS at the moment!
FWIW I do have an Intel CPU (silly me in this day and age!).
GPU: 2x RTX 3090 FE, 2x RTX Titan FE (light OC to both)
CPU: Intel i9 10980 XE (heavy OC)
RAM: 256 GB Corsair DDR4 3000 MHz (downclocked)
PSU: 2x Corsair HX1600i (2 x 1600W)
Mobo: Asus X299 SAGE (I have run the same setup on an EVGA X299 DARK too)
OS: Windows 10 Pro x64
DAZ: 4.15 Beta
Nvidia Driver: 456.71 SD
Turns out I had wrongly specified my driver verison number in my first post, but sounds like the OP tried 456.71 SD also.
I can run DAZ fine in this config, but maybe I'm lucky or maybe there's some AMD shenanigans.
Windoes 10 is version 1903 BTW. I remember needing to update for some reason when I got my 3090s (may or may not be DAZ-related).
So much for that theory :)
This is my setup:
I have it WORKING by the way, so we actually don't have a data point for "3090 + AMD + DAZ working" or "3090 + Intel + DAZ not working".
rafa, did you try the benchmark? > https://www.daz3d.com/forums/discussion/341041/daz-studio-iray-rendering-hardware-benchmarking#latest
last current page right at top, skyeshots has 2xMSI3090 and benchmarked fine. Tho he has intel CPU too, and it's on DS4.14. Another test to see how your PC setup holdsup.
Dearly hope it's not AMD CPU related. Arriving shortly at my house is a stupidly expensive mobo for a new 5090x when they become available again.
I don't see any indication that 3DMark tests CUDA, so it isn't necessarily showing that Iray should work. I'm not seeing much detail on what the OCCT 3D test does.
I did a benchmark test with 3D Mark and OCCT. Both were fine. Also the power consumption is OK.
And I'd like to know if there's someone who's working with the MSI Gaming X Trios and has no problems. This would be very interesting of how he/she succeeded in that.
As I already said. I had two Titans RTX before and they were working flawlessly, even though only with a very old driver. So, I'm pretty sure that in my case it's a driver issue. Maybe other 3090s have less problems with Iray than the gaming x trio from MSI.
That would sound like an issue with the card, in geenral or one of your specific items, not a driver or Iray issue. You'd need to check the benchmark thread to see which models those people used.
THere's some pretty sharp cookies in that benchmarking thread. If your benchmark does not meet expectations, wouldn't be suprised if some further suggestions are made.
I might reach out to support to see if I can get a copy of DS 4.14. I had no issues through December running my card with the latest Nvidia drivers + 4.14, so I'd like to rule that out.
Last post I saw in official DS support re: asking for older version, the Daz-user reported back that support was saying no longer available. In your case of troubleshooting the GPU, hope they make an exception and unarchive 4.14 again.
Make backups of all my old versions.
Thanks - I'm not overly optimistic, but I'd love to troubleshoot this some more. The last DS backup I have is 4.12, so I really need to be more on top of archiving them for this exact reason.
Well. Here's my benchmark test with 3D Mark. Everything looks fine. How it would be possible that both cards work fine with games but if it comes to Iray, they have an issue???
Especially I also tested DS with single Cards. So, this would be really a huge coincidence that not only that both cards, even though not having issues with games, have issues with DS, and are both defect at the same time!
Plus if there would be a defect with the cards, there wouldn't be any Iray preview and rendering at all. But sometimes it works. But not for a very long time. I succeeded once to render with both cards till 18k iterations. In the preview it works for a few seconds, then I get that weird bug https://i.postimg.cc/Bbbv98nF/1.png After I hide an object, the Iray preview works again, but only with 1 GPU. This all doesn't look like a defect of the cards but rather a incompatibility between these particular MSI 3090 model and Iray!
"much weaker", umm no. Miniscule difference.
It's a 3090, same GPU under the cooler as all the rest.
Or it could be tempeature or power related, if Iray applies a different kind of stress to the cards than your tests. You really need a test that taxes CUDA.
My temperature is pretty low. Only after 20 minutes of rendering it reaches 60 degrees! Never more! Even with long stress test it wasn't higher than 62 degrees! That's nothing! And I tested it with only one GPU as well and it failed as well with the same issues. And don't tell me that 1300 Seasonic Watt are not enough for that MSI 3090!
Of course I would immediately buy a 1600 Watt PSU. The problem: there are only 2. The corsair ax1600i and the EVGA 1600 T2. Both are out of stock everywhere in Europe thanks to our annoying corona policy!
And how exactly should I test the CUDA?
I don't know of others, but Geekbench provides a CUDA benchmark (https://browser.geekbench.com/cuda-benchmarks)
OK, then please explain me, why I got the issues I got with Iray! Since 4 days I'm struggling with it and still didn't find any solution. I tried absolutely everything up to reinstalling windows 10! Tried it even with only 1 card. Every benchmark test was OK. And it's very unlikely that both of my cards are defect! My previous Titans RTX worked fine even though with a very old driver. So... why do I got these problems if not because of an incompatibility of my particular 3090 model and Iray? And you say it's the same GPU. But how do you know that what MSI did to enhance the power of it doesn't have any side impact on Iray and DS?
So, what was changed in your system 4 days ago? Did Windows 10 install any updates then?
