NVAPI_ERROR
#1
Hello everyone!
I try to start hashcat (wordlist brutforce) on my rig (win server 2019 with 10 of RTX 3080ti) and it crashes after about 10-20 minutes with unknown error.

I tried:
1. Upgrade/Downgrade nvidia drivers;
2. Downgrade hashcat version (all down to 6.2.0);
2. Expand swap file up to 120 GB;
3. Use different mods (-w option) doesn't impact;
4. Use different wordlists (100 and 400 GB);
5. Use different hashtypes;

Any other conditions:
- Windows server 2019
- RAM 64GB
- Intel core i7 7700k
- NVIDIA EVGA RTX 3080ti (10 devices)
- ETH miner works stable
- Any of 7 cards works stable. The problem start with 8th device
- Temp max 60 C
- Don't use any boost. Just default settings.



Thank you for any help!

hashcat output below:
