I just wanted to share some findings with my new dual 5090 system. For the last few weeks I have been dealing with some very bad mysterious GPU crashes and it turns out this whole time it's been HWiNFO which I have used for years to monitor temps and other data on my PC.
If I had HWiNFO running while I was working in C4D and Octane sometimes one of my 2 5090s would drop out, all fans blazing to 100%! I almost RMA'd one of my 5090s that I thought was the culprit but this whole time it was HWiNFO!
Here's what Google Gemini thinks "Driver Collision: The NVIDIA driver is also constantly communicating with the GPUs to manage their power states and performance. A "race condition" can occur where HWiNFO and the NVIDIA driver try to access the same sensor at the exact same microsecond. This collision can cause the driver to time out and crash, leading to a black screen or a GPU dropping out."
Not sure how accurate this is but I wanted to the the Octane dev team know about this awful issue!
I hope Nvidia can get this sorted out with some driver updates ASAP.
DO NOT USE - HWiNFO - with Blackwell GPUs!

Very interesting!
Thanks for sharing!
My suggestion is to also post it in Video Cards / GPUs and Drivers section of the forum:
viewforum.php?f=11
In this way, not only c4d users and devs will see it.
ciao,
Beppe
