This post contains the instructions on how to fix the latest 460.79 Nvidia Windows driver. The reason for the problem is that one of the DLLs (nvml.dll) that the driver installs is corrupted. Here is what you have to do in order to fix the problem:

Download nvml_460.79_win10.zip from here: https://mega.nz/#F!2VskDJrI!lsQsz1CdDe8x5cH3L8QaBw (MEGA)

If you want to check the integrity of the downloaded file, please use the following hashes:

Code:

Extract the file nvml.dll from the .zip archive you have downloaded in the previous step, and then copy it to the folder C:\Windows\System32. There will be a file with the same name here, so you have to overwrite it (you will be prompted by Windows are you sure, blah, blah, blah)

Note that this .dll is the original .dll from Nvidia (it is still digitally signed by them). If you are really paranoid, you can download 460.79 drivers from Nvidia, then use 7zip to open the .exe and extract the dll (you will find it at 460.79-desktop-win10-64bit-international-dch-whql.exe\Display.Driver\nvml.dll), and then copy it to the C:\Windows\System32 folder.

Hello. I'm currently using Phoenix Miner 5.5c and getting this error message with my NVDIA GPUs. I have already copied the nvml.dll to c:\Windows\System32\ and still getting the same error. Any suggestions?

I'd go to the Nvidia website, grab the latest driver and do a clean install of the driver.

Here's the link:

This didn't work

What card is it and did you install it with admin privileges?

I have a mining rig with 5 GPUs. Three of them are RX 580 8GB and two of them are Nvidia 1070 8GB / 1060 6GB. I'm getting the error for the Nvidia ones.

2021.01.31:16:14:30.562: GPU5 GPU5 initMiner error: Unable to initialize CUDA miner

I tried older drivers - 442.74 - no luck
I tried using the most recent drivers - 461.09 - no luck
I tried replacing the nvml.dll mentioned in a previous post - no luck

This is a relatively new mining rig but it was mining just fine for about one month until two days ago.
