stable-diffusion-webui-amdgpu [Bug]: torch.OutOfMemoryError

Checklist

[x] The issue exists after disabling all extensions
[x] The issue exists on a clean installation of webui
[ ] The issue is caused by an extension, but I believe it is caused by a bug in the webui
[x] The issue exists in the current version of the webui
[x] The issue has not been reported before recently
[ ] The issue has been reported before but has not been fixed yet

What happened?

I tried generating an image with the same setting as another image that i had already generated and it ran out of memory. Even if i remove the Hires, fix it still runs out of memory when generating a 832X1216 image. It doesn't seems to happen when its 512X512.

Steps to reproduce the problem

Generate image higher than 512X512 (i tried with 832X1216 as its the same resolution as a previously generated image and 1024X1024)
Generation stops at the last step where it stays for a while until it runs out of memory.

What should have happened?

It should generate images bigger than 512X512 without running out of memory.

What browsers do you use to access the UI ?

Mozilla Firefox

Additional information

I'm running a 7900XT with 20GB of vram witch i think should be plenty. Seems to be happening after the last webui update.

I think there might be a memory leak... Along the path C:\Users\User\AppData\Local\ZLUDA\ComputeCache a cache is stored. Mine is 113 MB (119,242,752 bytes) in size, and if it starts to grow beyond that value, I can get an error like the one above.

I've also noticed that the generation speed drops with each attempt to generate a new image as the zluda.db file increases in size.

Well, mine is 628 MB (659.488.768 bytes) in size which seems like a lot. So if i delete the file every time it grows in size i may be able to generate images again?

I am having the same problem with my 6800. It is getting to 98% completed, then the task manager showed a massive spike in GPU memory (utilizing all of my dedicated memory and tried to use shared memory).

Edit: Just tried to do 832x1216 w/ hi-res upscale (goes to 1248x1824). It will shoot up from 10 GB to 29 GB at 98% completion (stayed below 15 throughout)

Every video card has its own ZLUDA cache size. If you constantly delete it, you will have to wait until it rebuilds itself. It's better to do this: delete zluda.db and perform your usual actions in the WebUI. Here is what I do:

Start with any Stable Diffusion neural network. It doesn't matter if you write a prompt or not; the goal is to generate the first image.
Once you have the image, use Hires. fix, then go to img2img, and use the SD upscale script. 3.Check the it/s (iterations per second) rate and make sure the WebUI has not crashed, then we copy the zluda.db file.

In other words, you need to perform your typical actions in the WebUI to get what you could call a 'clean' zluda.db file. And if problems begin, delete the 'working' zluda.db and replace it with the one you copied earlier. I also don't understand at what point the zluda.db file gets corrupted; I didn't notice this problem on ROCm 5.7, but it is no longer supported.

@EygenCat Where is this zluda.db file? I can't find it when I search for it with explorer. Do you mean delete the .zluda folder?

Sep 11 '25 18:09 maric193

@maric193 The file zluda.db is located at C:\Users\User\AppData\Local\ZLUDA\ComputeCache, where User is your Windows username. Is it possible that you are running SD under a different user "account"

I found it. Was looking in the wrong place.

After trying this out it still gives an "out of memory" error (with a massive GPU spike). It even gave that error when resizing using the SD upscaler.

Are you sure you're using ZLUDA? Not directml? If ZLUDA really works. Does that mean one of the modules was not installed correctly? I don't know, you didn't provide any information.

Unless this program overrides the command below, or there is some setting that was not mentioned in the installation, I am pretty sure I am using ZLUDA. set COMMANDLINE_ARGS= --use-zluda --update-check --skip-ort --skip-python-version-check

The high vram usage comes from the vae step after the highres fix. To prevent this you can do a few things. Get the FP16 sdxl vae file if you use sdxl/pony/illustrious based models. Set the Hires Steps to 10-15 and not higher. Download and install the Tiled Diffusion & Tile VAE Extension from here: https://github.com/pkuliyi2015/multidiffusion-upscaler-for-automatic1111 When installed relaunch Auto1111 and when you use Hires Fix always and only enable the Tiled VAE option at the bottom. Ignore the other settings from tiled diffusion etc. Only Tiled VAE will help.

I've tried again with a clean install and just by selecting the model the error happened again. All i've done is install the UI and copy the "waiIllustriousSDXL_v150.safetensors" checkpoint, then i selected it and the error happened freezing the computer for some seconds. Logs:

Make sure your on the latest AMD Adrenalin Driver (25.9.1) Then I see youhave HIP SDK 6.2 installed but the latest Version is 6.4 So uninstall everything from HIP SDK then install HIP SDK 6.4 and then reboot the PC. Also uninstall Python 3.10.6 and install Python 3.11.9 64bit for a better support of modern webuis and tools. Then delete the venv and .zluda folder from the stable-diffusion-webui-amdgpu folder. Then make sure you use these launch args: --use-zluda --update-check --skip-ort --skip-python-version-check in the webui-user.bat Finally relaunch the webui-user.bat

Also make sure your not running Wallpaper Engine in the background. It can cause massive issues while generating images. ALso how much System RAM do you have? If 16gb then you need to increase the Windows Pagefile.

I uninstalled HIP SDK 6.2 and installed HIP SDK 6.4 also uninstalled Python 3.10.6 and installed Python 3.11.9. I also did a clean install and used --use-zluda --update-check --skip-ort --skip-python-version-check. And i uninstalled my GPU drivers using DDU and installed the newer version.

After all that i started web ui and tried to use waiIllustriousSDXL_v150.safetensors again, this time i could set it as checkpoint and generate some images but as soon as i used Hires fix it ran out of memory again. I have 32GB of DDR5 ram and a 7900XT with 20GB of vram. This is the generation parameters i used:
