That's on the Intel defect list. So regardless of whatever else you're doing, make sure you have at least the microcode version 0x12B or later as mentioned at https://community.intel.com/t5/Blogs/Tech-Innovation/Client/Intel-Core-13th-and-14th-Gen-Desktop-Instability-Root-Cause/post/1633239 [community.intel.com]

well I have installed the latest bios and chipset software availble on day 1 (Pc is about 2 months old) but for safety (thanks for the links and post) I double checked

and it shows I have version 12B not sure how I can version up this but it appears not to be the wrong version I hope.

so if you have this latest bios / chipset updates installed as Edward's post details and links above and still crashing with segmentation faults on a new build - check your device drivers for errors!

also. I had a few more Segmentation fault crashes when changed some settings on the pyro OUCH! so deleted preference. Nope. installed the latest production build 20.5.487 (from 20.5.445) and it seemed to have got past the segmentation faults from where previously it was crashing.

FIngerts crossed its stable!

Ha! new build asus tuf , 96GB DDR5, intel i9 149000KF ,asus tuf 4090. crashing reliably every time on a pyro sim. tried all over the above including loads of stuff Ive never heard of. that process lasso is pretty cool piece of software but did not help one bit. last poster 'paranoidx' glad you found a fix but im not sure turning off XMP is a solution if you want fast DDR5 ram? ive done memory tests no errors ran benchmarks, performs stress benchmark tests really well. no issue with overheating or cooling or memory or CPU heating is causing the crashes. but Unreal engine and houdini crashes consistently. houdini more than unreal funnily enough.


it became much more stable with the latest nvidia driver that came out recently for the 5090s which seemed to help my 4090 BUT I could catch it out on a simple pyro sim consistently.

so just before submitting a bug after noticed a LOT of similar posts about voltages and BIOS and what and tried all these solutions out to no avail, but SideFX support themselves say there is an issue with 3D audio drivers - especially ASUS ROG. hmm!

so device manager showed no problem with audio drivers but DID have 2 devices with errors one unknown the other called device acpi intc10a0\ietm requires further installation so a quick search and there IS device driver for these on the asus website. just not immedietely available and had to expand a few triangle divots to access them. something to do with intel chipset for one or PCI - who knows? /shrugs.

anyway the good news is clearing out the non installed devices by installing the correct drivers seemed to have got past my consistent segmentation fault crashing in houdini (so far) whenever timelime playback or caching of a very simple pyro simulation

for the next person along want to contribute thier fix

this does not work as of houdini 20.5.445 production build Ive done all that said above, toggled compute / import on the FBX options in unreal I never get smoothing groups to arrive am using ROP FBX character output if that makes a differnce?
