Potential Dx11 Crash Fix

Hi guys, posting this in the hopes that it helps someone else plagued with the Dx11 crash.

A few months ago I was getting sporadic crashes with FF14, I couldn't figure out what on Earth was causing them, the only improvement I was able to find was using a specific BIOS version which made the crashes less frequent (I could still encounter a crash as soon as I logged in, or after 2 hours+ of playing). I wasn't having issues with any other games and given the numerous other complaints about Dx11 crashes with FF14 I expected it to be a bug with the game.

I tried everything I could think of/what was suggested, reinstalling windows, disabling overlays, compatibility mode, changing drives etc. Then the other day I found a video that suggested running Prime95 to see if any errors were found. I had run other benchmarking tools and had no issues (memtest, cinebench etc.) and at first I had no errors in Prime95, but after letting it run for a while it eventually gave a rounding error on one of the workers (as the video had shown), disabling the core that had the error seemed to fix this, along with the Dx11 errors. Given that my build was running at stock settings it shouldn't be having any issues, but I wanted to try and resolve the dx11 crash without having to disable any cores. I had a look into what could be causing this and saw some suggestions that maybe the CPU wasn't getting enough voltage and that this could cause the rounding errors. I changed the Precision Boost overdrive from Auto to Enhanced Mode 4 in the BIOS and now it appears that the Prime95 rounding error is gone, so is the dx11 crash and I don't need to disable any cores! I have been playing for a few days with no issues so I'm quite hopeful that this was the fix for me. Strange how this issue was only occurring in FF14 though...

I'm using a Ryzen3700x so not sure if these issues can be fixed in a similar way for intel, but hopefully this helps someone else!

TL;DR: PC running at stock settings, months of Dx11 crashes (FF14 being the only game to encounter any issue), ran Prime95, eventually had an error show, changed Precision Boost Overdrive in Advanced CPU config in the BIOS from auto to Enhanced Mode 4 and now all crashes have stopped without having to disable any cores.

I am also curious if windows fast boot has any impact to this...

I always disable it because I run into issues with cold boots whenever I have it enabled.

Does it help with DirectX Error 11000002? If so, can you make a step-by-step instruction on how you fixed it?

Same situation and all I had to do was lower my Ram from 3200 to 3000 MHz

but if it clock speed related, wouldn't a cpu prime stress test/gpu stress test also yield these same crash results?

I had at least one DirectX 11000002 error, the majority that I had were the ffxiv_dx11.exe+###### (random entries per line) errors, sometimes the game would just crash out with no errors. I haven't had a dx11 crash since making the BIOS change, I think in my case the CPU may have some issue with a couple of cores due to the voltage maybe? It was just strange how only FF14 revealed these issues (until they eventually occurred during the Prime95 stress test).

The exact steps I took to fix it were:

- Running Prime95 stress testing tool
- Leaving it running until a worker failed with a rounding error (It so happened that 2 of them failed, the workers corresponded to the logical processors shown in task manager, open task manager and go to Performance -> CPU -> right click on the chart and select change graph to -> Logical Processors)
- At this point, two different processes fixed it for me, 1 was disabling the corresponding cores in Ryzen Master (Going into game mode, selecting the Cores Section and left clicking to disable the cores that were failing), the other which I did to get around having to disable the cores was going into the BIOS and updating the Precision Boost Overdrive setting (Go into the BIOS -> Advanced CPU config -> Precision Boost Overdrive -> Change from auto to Enhanced Mode 4)

I'm not 100% sure how this fixes it, I'm assuming the enhanced mode applies more voltage maybe? But whatever it did, it fixed all the errors, I haven't had one since. I had tried pretty much everything everyone else suggested to no avail, hopefully this helps you! Also it's probably worth noting that I didn't get the errors in Prime95 straight away, it took >15-20 minutes or so before they showed, but after that it encountered them rather quickly.
