CUDA 12.5 build produces visits/s = -nan(ind) even with compatible cuDNN and model

[Immow]

Hi, I'm having trouble getting the CUDA 12.5 version of KataGo to work on Windows 11. The binary runs, but all benchmark tests fail with visits/s = -nan(ind) output — no matter what I try.

Setup
OS: Windows 11
GPU: NVIDIA RTX 5070-class (Ada Lovelace)
KataGo Version: v1.16.3-cuda12.5-cudnn8.9.7-windows-x64.zip
CUDA: cuda_12.5.0_555.85_windows.exe (installed via NVIDIA site)
cuDNN: cudnn-windows-x86_64-8.9.7.29_cuda12-archive.zip cudnn64_8.dll copied into same folder as katago.exe
Model Used: g170e-b20c256x2-s5303129600-d1228401921.bin.gz

Steps Taken

Set PATH for CUDA 12.5 (nvcc --version confirms 12.5.40)

Placed the following DLLs in the KataGo folder:

•     cudnn64_8.dll
  

•     cudart64_120.dll
  

•     cublas64_12.dll
  

•     cublasLt64_12.dll
  

•     and other common dependencies from CUDA\v12.5\bin
  

Generated config
katago.exe genconfig -model g170e-b20c256x2-s5303129600-d1228401921.bin.gz -output default.cfg

Then ran
katago.exe benchmark -model g170e-b20c256x2-s5303129600-d1228401921.bin.gz

Problem
numSearchThreads = 5: 0 / 10 positions, visits/s = -nan(ind) (0.0 secs) No crash or error — just zero evaluations and NaN results.

What I've Tried

• Verified model integrity and tried smaller networks
  

• Rechecked that all DLLs match the CUDA version (12.5)
  

• Ran from elevated CMD with full path access
  

• Installed both Runtime and Development parts of CUDA 12.5
  

Questions

• Is the 12.5 CUDA build tested with cuDNN 8.9.7?
  

• Are there known compatibility issues with Ada GPUs?

This "problem" is normal. When it is at "0/10 position", it will show "-nan(ind) (0.0 sec)". You need to wait a minute for the process to run.
