OBS Crashing every few minutes

[TheDammitch]

Hello. I've been having a great deal of issues lately with OBS. Today it crashed ten times within three hours. At first I could see that it didn't like some StreamElements stuff, so I removed all of it. And I do mean all of it. Those were showing up in my Log reports, which I could at least read.

I'm running Windows 10, and OBS 29.1.3, on a Ryzen 7 3700x, 64 GB of RAM, and an Nvidia RTX 4070 GPU.

This is my most recent crash log, which I don't know how to read. If anyone can tell me why it crashed, and how to fix it, I'd be very, very grateful!

Previous crash logs list errors in threads, most recent to oldest, all happened today:
4B09
6790
6C98
65EC
80C8
5D8C
80E8
5E60

I can't find how to tell what these threads are, or what they mean. How are we supposed to determine the reason for crashes?

It looks like an issue with the x264 encoder. Does this happen if you use the NVIDIA NVENC encoder?

This is a sign of a hardware failure, typically an unstable overclock, overheating, outdated BIOS or faulty RAM. Try memtest86+ and Prime95 / OCCT to test your system for errors.

This is what I get when I attempt to use the NVIDIA NVENC encoder:

I have nothing else recording, and don't use Shadowplay or any other DVR stuff. It's a fresh, clean install of a brand new GPU.

What about a complete reinstallation of the NVIDIA drivers

Display Driver Uninstaller (DDU) download version 18.0.8.3

Download Display Driver Uninstaller (DDU) - Remove AMD/NVIDIA/INTEL Graphics Drivers Cleanly - DDU is a driver removal utility that helps you completely uninstall AMD/NVIDIA graphics card drivers and packages from your system, leaving no leftovers behind, including registry keys, folders, files...

Also, it will not be superfluous to take a look at the log file.

I have run memtest86+ and my RAM passed.

I was able to a full uninstall and reinstall of the NVIDIA drivers, and finally get NVIDIA NVEC encoder to work in OBS, after reverting to OBS 28.0.3.

I am still getting OBS crashes within ten minutes of starting streaming in Bandwidth Test Mode. CPU never went about 20% load while I was watching.

Attached is the most recent Crash report, and the three Log files which were generated from that test run.

In addition, I did run Prime95 on this system last week, for about a five hour period. CPU never exceeded 74 degrees Celsius, so I do not expect overheating to be the culprit.

Unfortunately pretty much every x264 crash we see is the result of hardware issues. x264 is very old and well-tested and has no real crash bugs like this, but it does have high performance assembly instructions that push your CPU and memory to its limit. Such code can typically expose hardware bugs that other programs don't trigger. It may take multiple days of continuous testing with Memtest / Prime95 to reproduce such issues.

There is something screwed up based on your memtest results, L3 cache and memory bandwidth are to low for your system. Try it with a UEFI update and/or reset.

AMD systems also implement some overclocking-like features in a way that can cause this crash.
