RTX4090:an illegal memory access was encountered

edited October 2023 in Technical Help (nuts n bolts)

Hello everyone, just wanted to share something I've been grappling with and see if anyone else has run into the same issue. I recently upgraded my GPU from a 2080ti to a 4090, expecting some serious improvement in rendering performance. However, something weird is happening.

Scenes that I had zero problems rendering with my old 2080ti are now failing to render with the new 4090.

Has anyone else experienced this? it's super frustrating. Any insights or advice would be awesome.

Ram:32gb

RTX4090 24gb vram

AMD Ryzen 9 3900X 12-Core Processor               3.80 GHz

Daz version: 4.21

Game ready driver:536.99 (Just roll back from the latest game/studio version because it got me bsod when I tried to render with the latest version.)

PSU:850w

    Did you monitor the vram usage with GPU-Z or Task Manager or sth. ? Could you remember the module or error code from BSOD?

    Pls see if the vram usage is normal or not. And there is chance to first use DDU to 100% uninstall the card driver and residuals, then install a fresh Studio driver, to eliminate BSOD...

    Before I roll back the driver version, I tried both latest game and studio driver, both gave me BSOD when I tried to render or Iray preview the scene.When I rolled back to the game driver I mentioned aboved, it just gave me a black render, did not used GPU at all.(CPU fallback disabled)
    BSOD stop code: DPC_WATCHDOG_VIOLATION
    Here's one of the dmp file:

    Oh... I don't think your scene consumed nearly 24GB VRAM but usally with CPU fallback disabled, a black render results from running out of VRAM. However your DS log shows a failure of de-allocating memory which is wierd. Post the full log if possible.

    As for - DPC_WATCHDOG_VIOLATION, I strongly recommend using DDU to uninstall your driver first and re-install the latest Studio driver. DDU ever helped me twice to resolve BSOD, once is nvlddmkm.sys error, once is DPC_WATCHDOG_VIOLATION.

    https://www.wagnardsoft.com/, click DDU latest version.

    BTW, what's the power of you PSU？

    Strange things have also been happening if one has installed Iray development packages etc. from nVidia, as they have installed different (not compatible with ones DS uses) versions of nVidia related files.

    Complete unsinall and reinstall to the latest game driver this morning. Just try to rendered and yea no more BSOD. But the gpu problem is still there. Here's a complete log hre, I deleted lines that were loading images to save you some time.

    The weird thing is, the scene rendered with gpu for about 91 iterations then refuse to use GPU.

     I don't think I installed any devdelopment packages from NVIDIA, it is really weird

    In the same scene, after gpu render failed. The iray preview failed as well, heres the log for the preview:

    Yes, if the GPU fails to render it is usually necessary to restart DS to free it up.

    It's a good news that BSOD is gone. Then after checking your full log attached, still suggest as below -:

    0. Uninstall Optix 7.3 SDK ! (If everything's ok after testing, and you DO need SDK, install the latest 8.0 version and re-test.)
    1. Install GPU-Z to monitor your 4090 performance esp. VRAM used and GPU Load (as attached).  Observe GPU-Z panel the moment you click Render or press Ctrl + R. Pay attention to the value change of 'Memory Used'.
    2. Use a Studio Driver rather than Game Ready Driver.

    Then let's see...

    • Switched to studio driver
    • GPU-Z checked, no issue with empty scene.
    • Upgraded to Optix 8.0 SDK(I don't really know how to uninstall)

    The scene successfully rendered up to about 800 iterations before refusing to use the GPU and aborting the render. Compared to before, when it rendered only 0-90 iterations before aborting, this is a slight improvement but still doesn't fix the issue. The log is still the same.

    There is an screenshot of GPU-Z during rendering, before it refuse to use gpu.

    Hmm, it's progressive though it's a tough problem...and what was shown in GPU-Z looks normal. But the error last time is Kernel [19] ( MaterialSurface ), this time it's Kernel [8] ( ShadowEvalSr )...

    Again, you must try a couple of tests without Optix SDK !  Just go to Control Panel - Programs and Features. Locate or search Optix in the upper right corner. Uninstall it and reboot your PC.

    Initiate a new test. While the rendering reaches in b/t 800 - 900 iterations, pls carefully monitor the panel of GPU-Z, first see if the data in Memory Used suddenly jumps to a high value, 2nd, if GPU Load suddenly drops down...

    Then let's see...

    Hmmm.. Did a few tests:

    • Before unintalling optix8.0, rendered 80 iterations before aborting renders
    • After uninstalling optix8.0, rendered gave me BSOD
    • Reinstalling optix8.0, rendered 2 iterations,  (Kernel [19] (MaterialSurface) )

    It seemed like the one time I had 800 iterations was just pure luck; it's kind of random. The memory usage was stable, and the GPU usage dropped once the render was aborted. The other lines are the same old "an illegal memory access was encountered (while de-allocating memory)"

    Well, seems like a mojo...

    That's why I never touch SDK... but I just suggest you a last try :

    1) carefully check if you have installed other Nvidia SDK, whatever they're , uninstall them all.

    2) you have to again, use DDU to uninstall everything and clean residuals, then install a fresh new driver. Then test. If the issue still sustains... options: contact the reseller for support, or test the card on other PC, etc.

    I just 

    • Seem to be the issue with my current ram, I upgraded them to 128gb.
    • Returned the card and switched to a differnt brand.

    And these actions seemed to fix the problem, the scene can render perfectly without aborting renders. I don't know if it have to do with the graphic card, but yea having larger ram seem to have a fix on the problem.

    I don't think it was RAM issue but most likely graphics card issue, as after the scene is fed in VRAM, there'll be nothing to do with RAM...

    i have the same issue here

    i have an AMD GPU and a Ryzen 7 CPU

    memory explode with 2+ characters on render and crashes, with one char and nothing more, still usable.

    my guess is a problem with the configuration of AMD CPUs

    I found this thread from google and thought I'd chime in even though it's old. I had the same issue with a 4090 laptop edtion, 16GB of vram, lenovo legion pro 7, 33GB of system ram. The workaround I found was to reduce the GPU cTGP setting to 125W. This can be found in the Lenovo Vantage app under Thermal Mode -> Performance. I used to get the illegal memory access after about 30 minutes of rending and now I've let it go for an over an hour and have yet to get the error. As others have noted, it doesn't seem to matter how much vram is used as long as it's less than the total vram available to the gpu.
