Gigapixel, Denoise (and more?) crashes video card when using the RX580 for processing

Hi folks…

I have the latest versions of the Topaz products and the most recent graphics driver for my RX580 4GB.

In the past couple years (with both the current and previous versions of the graphics driver) I had no problems and the RX580 worked well. But after updating the various Topaz products over the past few months, one by one they started crashing the graphics driver/card (where all screens (3) go blank and I have to reboot the computer to recover).

So far DeNoise, Sharpen, and Gigapixel exhibit this behavior.

It happens when I am adjusting settings and previewing, as well as while processing the photo(s). Happens every time.

My only solution is to tell the Topaz product to use the CPU.

Any idea what’s going on?


I have the same issue with a AMD RX580. Both Sharpen and Gigapixel keep crashing

Topaz got back to me via email. I tried a couple images, and the problem seems fixed, at least with Sharpen Ai - I didn’t have a chance to try Gigapixel - I will when I get a chance:

Thanks for reaching out and my sincere apologies for the long-overdue response. We experienced some staffing shortages due to covid-related illnesses, but should be back to our normal response times (less than 8 business hours) shortly.

For Sharpen AI, I’d ask you to do the following:

  1. Un-install
  • Navigate to the Windows Add/Remove Programs page (or search for it using the Search bar) > Search for Topaz Sharpen AI and click ‘‘Uninstall’’
  • Go to C:\Program Files\Topaz Labs LLC and delete Sharpen AI folder if there is one
  • Go to C:\ProgramData\Topaz Labs LLC and delete Sharpen AI folder if there is one.
  1. Open program RegEdit from your Start menu explorer and delete the registry entries of Topaz Sharpen AI, if there are still any, in:
    Computer\HKEY_CURRENT_USER\Software\Topaz Labs LLC\Topaz Sharpen AI
    Computer\HKEY_LOCAL_MACHINE\Software\Topaz Labs LLC\Topaz Sharpen AI

  2. Re-install with V4.0.2

  • Download the software from: Topaz Labs Download Page.
  • Reboot your computer. Install the program without any other applications running
  • Open the program as a standalone first to make sure it’s working for you

As for the issue with the 3 apps when running them on your AMD GPU, I want to rule out if this is a mechanical issue; i.e. a power supply issue. AMD GPUs sometimes cause some machines to crash with high GPU-resource intensive programs if the GPU is being somewhere at the peak and the power supply can’t handle all the usage. Can I please ask you to try turning the power limit usage of your AMD GPU and see if that makes a difference? You can do that in the AMD settings. For your reference, here’s: How to Tune GPU Performance Using Radeon Wattman Share this page. You can check the '‘Power Limit’’.

Please let me know if that makes a difference. Thank you, William.

Thanks for that, but did not help me. I have created a new help request

Same problem here. I’ve to reinstall the drivers gor my AMD RX 580

Same here with a AMD RX 480. GPU crashes, Topaz suggesting it is power related to the PSU, reading the number of issues here with a Gigapixel and Sharpen AI, I am very doubtful of the Topaz’s explanation
