Hey All
Even BEFORE BF6 was installed! this PC was rock solid. No crashes! No PC power resets! I have the following spec/config.
Watercooled PC
ASUS ROG MAXIMUS Z790 HERO (latest BIOS that supports the known CPU issues and enabling Intel Baseline Profile)
Intel i9 13900K
64GB memory
Windows 11.
RTX 4090
I am also running a:
UNDERVOLT on CPU

UNDERVOLT on RTX 4090 using MSIAfterburner

I am running the normal intel recommended CPU settings/threshold for my CPU (above YT links). The Board is NOT overclocked but I have lowered the CPU to sync cores to 52x or 51x and running a normal XMP memory profile - which is quite normal for any memory requirements. Running XMP is what the memory is meant to do!
So before BF6 I was running a very STABLE undervolted board / cpu / RTX 4090 - with Nooooooo issues what so ever.
I have been running BF6 since its release. It seemed fine at the start in October 2025. Odd crashes but nothing major (All RTX Nvidia related driver / card removed errors etc). I also experienced the random PC power resets on occasions during BF6 startup/playing Breakthrough.
This started to get worse. It definitely seemed worse when Season 2 was released (unless just coincidence). So I went looking on google… fk me! sooo many issues and known fixes to try. It was getting to a point that about two weeks ago within 1 hr of booting up the PC the PC had power reset twice and crashed on every BF6 start up when loading into a game. It had even told me that my BF6 files were corrupted. It did the same thing for at least another 10 times in a row straight after each restart of BF6.
Anyway I have tried all the known google fixes.
Tried new and old Nvidia drivers. Left it on Nvidia version 581.42. That’s known to have the best stability.
Removed XMP memory and set to defaults.
Removed CPU setting and set to defaults.
Removed MSI Afterburner profiles.
- NONE OF THE ABOVE KNOWN FIXES WORKED FOR ME. BF6 IS STILL CRASHING!
I believe that over time hardware/components can breakdown and become very sensitive and start playing up. They don’t handle the voltages/12v/5v rails like they used to. I assume whatever the issue is – it’s pushing the graphics / card / memory / PSU to a very high threshold/limit. Could this be related to the onging random crash issues?
I nearly got to the point that I thought the PSU was broken or my RTX 4090 was busted. Or the mofsets on the board was failing. I nearly stripped the whole PC down and was thinking I'd need to start replacing parts and swapping them out for testing etc but then I thought…Look the PC is fine! It’s running an undervolt on the card the graphics and the cpu. It’s using less power / less volts / less heat. That’s gotta be a good thing right? Plus, no other games are causing this issue - its only BF6.
- THIS WORKED FOR ME FROM THIS POINT!
So, I put the PC back as it was to the original spec - with all the UNDERVOLTS (No Overclocks!)
I stayed on the Nvidia 581.42 driver.
I took a copy of the the working config folder (in case it crashed and got corrupt again!) I recommended that you do this! - C:\Users\<Name>\Documents\Battlefield 6\
I changed my BF6 Graphics to performance and lowered the spec a little. I kept textures high but lowered others. I basically followed this guide:

- ONE THING I DID NOTICE IS….
I think maybe/could the BF6 FPS option be trying to allow up to 240 FPS. I can’t recall if the Frame Rate Limiter was ON or OFF before? but I thought is BF6 trying to get 240 FPS all the time and that’s really going to push my OS and CPU and GPU to the point that something gives out and throws a reset/crash - then maybe I can back it off a little. Take the pressure off as such?
I made sure the following was set in GRAPHICS > ADVANCED SETTINGS:
Fixed Resolution Scale 100
Frame Rate limiter In Game ON
Frame Rate Limit in Game 240 - I DROPPED IT to 100 then tried 120 then 150 - and stayed on that. So far All OK!
Frame Rate Limiter - In Menu ON
Frame Rate Limit - In Menu 60
Frame Rate Limiter - in Background OFF
NVIDIA Reflex Low Latency ENABLED+BOOST
Upscaling Technique DLSS
Upscaling Quality QUALITY
DLSS Model 4.0
NVIDIA Frame Generation OFF
Future Frame Rendering OFF
Performance Overlay OFF
and yeahhhh so far it’s OK. I can’t say this will work for others… but there is nothing worse than having a game crash on you - so I hope this helps somebody. It’s been a week so far and I play every day and it seems stable since making these changes.
So yeah – if you have constant random crashes - Don’t overclock the PC/CPU/GPU. Try running a lower spec on graphic setting and drop the expected FPS frames? – See if it works for you. Good Luck Guys.
Kind Regards.
