Use mfaktc with AutoPrimeNet.

Why so many builds?

Different CUDA versions support different hardware (compute capabilites), and different driver versions support different CUDA versions. As such, we need multiple builds to support all the various hardware/software combinations.

Which build do I use?

The one that matches (or is the closest less-than-or-equal-to) the CUDA version supported by your driver.
e.g. Driver supports CUDA 12.1, use the build that targets CUDA 12.0.

To check your driver's CUDA version using the NVIDIA Control Panel, open the "Help" menu, "System Information", "Components" tab, look for filename NVCUDA64.DLL (or NVCUDA32.DLL on 32-bit) in the left column, then in the right column ("Product Name") you should see something like "NVIDIA CUDA 12.7.33 driver": the "12.7" is your CUDA version.
Another way to check is to run nvidia-smi (from a command prompt), which reports the supported CUDA version on the first line (on driver 410.72 and newer1).

The below table shows the CUDA versions and recommended builds for some of the more popular driver versions:
