NVIDIA has an answer to Steady Diffusion maxing out the obtainable reminiscence
Drivers have a brand new characteristic known as “System Reminiscence Fallback”.
The NVIDIA Management Panel should look previous, but it surely nonetheless continues to obtain characteristic updates. In a current driver launch, NVIDIA launched a brand new choice within the Management Panel tailor-made for client GeForce graphics playing cards. This selection is labeled as “CUDA – Sysmem Fallback Coverage” and is particularly designed to deal with memory-intensive workloads, corresponding to rising generative AI packages.
This characteristic is primarily marketed for Steady Diffusion, a course of which may demand as much as 6GB of reminiscence to be utilized concurrently. Nonetheless, since in style GPUs nonetheless characteristic most reminiscence capability between 6 and 8GB, the GPU reminiscence is perhaps nonetheless shared with different workloads stopping the total utilization by packages like Steady Diffusion. To handle this, NVIDIA has carried out a brand new characteristic that stops purposes from exhausting GPU reminiscence by effectively switching to shared system reminiscence.

From a technical perspective, customers have the flexibleness to make use of this characteristic for any utility, together with video games. Nonetheless, it is probably not the only option, as system reminiscence is commonly notably slower than GPU reminiscence, to not point out the mandatory knowledge switch between the 2.
The first goal of this characteristic is to avert potential crashes on graphics playing cards outfitted with 6GB reminiscence capability. With the newest drivers, NVIDIA has thoughtfully integrated an choice to disable this fallback mechanism. Doing so can doubtlessly improve efficiency stability however does reintroduce the chance of depleting GPU reminiscence.
How one can allow or disable System Reminiscence Fallback
- Open NVIDIA Management Panel
- Beneath 3D Settings, click on Handle 3D Settings
- Navigate to Program Settings tab
- Choose Steady Diffusion python executable from dropdown
- Click on on CUDA – Sysmem Fallback Coverage and choose Driver Default, Want No Sysmem Fallback or Want Sysmem Fallback.
- Click on Apply to verify.
- Restart Steady Diffusion if it’s already open.
