With that said, many folks have had crashing issues because their motherboard needs to be updated. Check to see if there's a BIOS update for yours.

Thanks, I've updated my post with my specs!

Does underclocking the core and mem to max negative values via msi afterburner help?

Seem to be a little less frequent when underclocking the max in afterburner (-502 core, -502 mem). Today when I run no man's sky it crashes within a minute on normal, maybe 2-3 minutes underclocked.

Riva tuner installed with After burner? Possible to disable Riva and try again I've had issues with tuner b\4

Few things not mentioned:
 
- Vram junction and gpu hotspot temps as measured by HWiNFO.  It can also read ICX temps.
 
- I usually have the best luck with OSD via RTSS and HWiNFO.  Sometimes I have to set overclock with X1 and then close it out, in particular with RDR2 to prevent stuttering.  However RTSS is known to crash 3dMark benches, so I bench with just X1 and no OSD.
 
- Can you pass 3DMark or other benches? Unigine? Furmark stress test?  Prime95 AVX?
 
- Have you tried X1 vs. Afterburner?  Most recent AB?
 
- What kind of GPU load are you hitting during crashes, are there any FPS limits in place and power limits?
 
- Have you logged GPU Performance Limit triggers in HWiNFO, reset at the start of gaming?
 
- Normal or "Prefer Maximum Performance" power settings (can be set by game) in Nvidia driver?
 
- Windows application compatibility settings and run as administrator?  Disable Windows Defender for game exe?
 
- Are you not using Geforce Experience? Most people here don't.
 
- The fact you are not holding underclock is suspicious but not unheard of.  I've not tested it extensively, but have had cases where the curve took but then stopped being obeyed after an hour or so. Turning down power limit, clock and limiting frames seems more reliable.
 
- Do you have good or bad 3rd 8-pin and PCIe slot power balance?
 
- 3 separate PSU cables and have you tried replacing the cables and reseating the card?
 
- Have you tried the normal XOC bioses, the Rebar Bioses or the XOC rebar Bioses?
 
- What is your definition of not overheating and good case air flow?  Some people think 80C is fine and have all glass cases with a front AIO, have poor airflow even with a bunch of fans.  Back side VRAM could still be getting hot.  What is your ambient room temp and air circulation around the case?
 
- Ever try another version of Windows?  I've not heard much about the EDU version.  I run the ancient 1809 W10E LTSC.
 
- Try a different, high quality/OEM displayport cable?
 
- Change to a different audio device?  Not using one of those wacky Nvidia audio processing utilities?
 
- Anything in the #2 PCIe slot?  Have you tried the GPU in the #2 slot? 
 
- How do the VRM/MOSFET temps look on that PRIME board?  The 5950X is pretty power hungry and the X570 Prime is the bottom tier X570 board.
 
I feel you pain, I had occasional BSOD crashes for 18 months on my main machine until I got a MB bios with better memory handling/auto timings.
 
 
 
 
 

Wow, so many things to consider. Thank you so much for your suggestions.

- Vram junction and gpu hotspot temps as measured by HWiNFO.  It can also read ICX temps.

PWR4 is always the highest reaching low 80s. Mem 1, 2 & 3 are equal to each other mid 70s, followed closely by GPU2. GPU1 is the lowest.

- Can you pass 3DMark or other benches? Unigine? Furmark stress test?  Prime95 AVX?

Unfortunately, yes. Furmark at 4k was steady at 76 degrees without any crashes. 3DMark Time extreme and Fire extreme both ran without problems. Time extreme stress test passed with 97.8%. Was really hoping to crash out in any of these.

- Have you tried X1 vs. Afterburner?  Most recent AB?

I've been updating regularly, currently Afterburner 4.6.4.16094, X1 1.2.1.0.
 

kevinc313
- What kind of GPU load are you hitting during crashes, are there any FPS limits in place and power limits?
 

I've tried both. I normally run with a 60fps limit. Crashes are occurring with loads of 40 or 50%. GPU temp is around 60degrees.
I have a big monitor so if I turn off limits it can run at 99%, but temp steadies around 70-75 degrees.
 

kevinc313
- Have you logged GPU Performance Limit triggers in HWiNFO, reset at the start of gaming?

Not specifically limits, but have logged sensors with hwinfo64, and at other times with x1 and icue (aoi temps and fans). I don't see anything that spikes or maxes when a crash occurs.

- Normal or "Prefer Maximum Performance" power settings (can be set by game) in Nvidia driver?

Tried to change pretty much anything i can, in driver, app override, or in-app. In six months you can cover a lot of permutations :(

Will try these tonight, worth a shot!

- Are you not using Geforce Experience? Most people here don't.
 

Normally yes with the osd disabled, but I removed it with a driver clean install.

- Do you have good or bad 3rd 8-pin and PCIe slot power balance?
- 3 separate PSU cables and have you tried replacing the cables and reseating the ca

I'm running three separate cables to the PSU. I had fancy corsair colored cables, but switched to the PSU OEM cables in the last few months.

- Have you tried the normal XOC bioses, the Rebar Bioses or the XOC rebar Bioses?

I'm not sure what these are, so I will check them out. I have tried enabling resizable bar without stopping the crashes.

Great point. I like a quiet system, so I'm running an o11 xl with six inflow and four outflow, with an aoi on the top outflow (yes, I went with aesthetics on that one). Fan is horizontal so the three bottom fans flow straight into the gpu. Most fans are ql120s, although I turn off all rgb.
 
Location seems good, clean uncluttered area in an open floor plan. Fan profiles are pretty conservative, ramping up fairly quickly with a final kick if anything hits 80. With most games the extra flow of all of those fans really helps the gpu stay low (60s), the exception being Ark which tries its best to melt everything.

- Ever try another version of Windows?  I've not heard much about the EDU version.  I run the ancient 1809 W10E LTSC.

The educational version is basically the pro, but with pretty much all the admin extras included. I think the idea is for cs students to get comfortable with the admin tools so they want to use windows in the field. I got it as a free upgrade when taking some courses.
 
I've been updating the os regularly without any improvements.
 

kevinc313
- Try a different, high quality/OEM displayport cable?

Yes, went with a cable club certified 8k60, 32.4Gbps cable (highly recommended) to drive my monitor. Was having some issues with the OEM cable and this new one was like magic.
 

kevinc313
- Change to a different audio device?  Not using one of those wacky Nvidia audio processing utilities?

I normally run off an external card (FocusRite), but have yanked that and even disabled onboard audio in the bios while trying to eliminate variables.
 

kevinc313
- Anything in the #2 PCIe slot?  Have you tried the GPU in the #2 slot? 

Nothing in the slot. I haven't tried it because bandwidth, but I think I'll give that a shot.

- How do the VRM/MOSFET temps look on that PRIME board?  The 5950X is pretty power hungry and the X570 Prime is the bottom tier X570 board.

Was originally a 3900x, only switched to the 5950x to try and solve this. With either, the southbridge gets pretty hot (like all x570s) but none of the other board sensors get above 60 according to hwinfo.

You posted that your Prime X570-PRO is on BIOS revision 3402? I didn't see that one listed, but 3405 and several newer versions (3 total) including the latest 4002 have system stability improvements.
 
You might want to update your BIOS and see if it fixes those random crashes like it has for others with AMD boards.

Sounds like you've covered a ton of stuff, happy to help.  Forgot to mention the MB bios update yesterday, someone hit on it above, looks like they are up to #4002, probably worth a try. 
 
Also (long shot) messing around with the number of cores running (like disable half) and turning off things like speedstep and hyperthreading, or the AMD equivalent.
