BSOD playing Battlefield 1, WHEA_Uncorrectable_Error

Hello there.

I have browsed a little bit through the forums and observed I am not the only one with this issue. The PC usually crashes an hour into playing Battlefield 1.
This is what I have tried so far:
- Updated BIOS and drivers through ASUS EZ Update
- Running the game on the lowest settings
- Removing two of my RAM modules (I bought one pair early 2014, and one pair mid 2015, for a total of 16 GB).
- Benchmarking/"torture testing" the GPU and the CPU, which they withstand. When I tried the same with RAM and power supply, the PC froze. I used Prime95 for this.
- From the little I can tell from running a basic analysis of the memory dump file, the problem seems to be hardware related.

I do not have this issue with other games or uses of the computer, like watching videos (I have read other threads where people had trouble with Youtube and such), and there is no secret that BF1 is a demanding game.
This is what I got so far. Please let me know if additional info is needed, and I very much appreciate any help.

Cheers.

Just reading through your troubleshooting method I would try a proper test of your RAM:

Diagnostic Test

 RAM TEST

Run MemTest86+ to analyse your RAM. MemTest86+ - Test RAM - Windows 10 Forums

   Note

MemTest86+ needs to be run for at least 8 complete passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero errors here. Even a single error will indicate RAM failure.

If errors show up you can immediately stop the test because you will know the RAM is faulty. You need to then find out which one by trying the individual sticks of RAM individually until you can pinpoint the faulty one. [Note that it is possible for a slot on the motherboard to be faulty too but lets hope this is not the case.]

Thanks for the reply. I am currently running a memtest, and I started about 10 hours ago. When I get home I will try your suggestion if any errors have shown up. As far as I have understood, the test just keeps running forever, so in a 10-12 hour span it should have been through several passes, and that is usually enough, or am I mistaken?

This bugcheck could point to hardware problem with your CPU, as you already said, but often also motherboard software can cause this kind of BSODs.

In this case it's an internal unclassified error, which means it's not publicly documented (which is ironic given it's "unclassified"). However, yes, it's clear you're dealing with an internal CPU fault and not one that could be generated by bus issues or any other external factor other than heat and voltage. Though make dead sure motherboard software isn't interfering; sometimes mobo software will generate CPU faults of this sort because of bugs in their CPU drivers.
Other than that, no, there's really nothing else you can retrieve from this.

I wasn't able to find many of these drivers in the given directory. Do you know where else to look? The EZ Update utility says there are no more updates, but I am aware that might not be entirely conclusive.
I am trying to get a hold of another power supply, just to try that as well. If it's not driver related, could there be something with unsteady power supply or some sort of voltage fluctuations (abnormal ones)?

Are you using or did you use any kind of this motherboard software like Asus AI Suite III, Asus Smart doctor etc. in the past.
If you can not find any updated drivers, i would (temporally) uninstall all this kind of software and see if this solves your problem.

Also, keep track of the CPU and GPU temps during gaming. I notice your CPU is 67°C in that screenshot. That is not too hot, but it is hotter than usual during that test.

Just tried a session with BF1 now. I used MSI Afterburner to monitor the CPU temperature. It was between 70 and 75 before the PC crashed again.
I also uninstalled the ASUS EZ Upgrade and other downloaded utility tools, as suggested by lifetec.
