Cuda Toolkit Version Compatibility with Nvidia P4000

Could someone tell how we can proceed to download the correct CUDA toolkit for a Specific VideoCArd?

I have Windows 10 Workstation with an NIVDIA P4000 with Driver Version Installed 430.86 and i have dowloaded cuda_10.1.243_426.00_win10 that is the CUDA Toolkit 10.1 Update 2

I choose that because i found capability 6.1 and in wikipedia from what i have understood

CUDA SDK 10.0 – 10.1 support for compute capability 3.0 – 7.5 (Kepler, Maxwell, Pascal, Volta, Turing)

is compatible from capability 3.0 to 7.5. is Correct?

Yes, correct. The usual suggestion without other information is to just use the latest CUDA toolkit.
