Consistent Crashing - Intel i9 14900K Could Be Your Problem

Good Morning fellow Drafters,

 

For the last 3 weeks I have been through hell with AutoCAD LT 2024 and Revit LT 2024 crashing on me constantly, every day, to the point where it would not open files. It started out of the blue. I contacted AutoDesk Support, My own IT support, and also the PC shop where I acquired my Custom CAD Spec Workstation. All were very helpful, but NO ONE could figure out why the software kept crashing. 

 

We did absolutely everything recommended by AutoDesk, cleaning up old CAD files, changing windows and AutoCAD settings, testing other versions and releases of software, switching Graphics Cards and RAM sticks and we even got to the point of re-installing Windows 10 Pro, Updating the BIOS, and running Heavy Load hardware checks. Nothing changed, and nothing showed as being a problem. The same random crashes kept happening, usually when re-loading Xrefs, inserting Blocks, or moving objects or drawing geometry in larger files. But even just opening files was crashing the software very often.

 

I could hear my Desktop fans whizzing into action every time a crash was about to happen.

I spent countless hours searching for hardware issues online and found some gamers noticing crashes with i9 13th and 14th Gen processors. I talked to someone who suggested that the Efficiency E-Cores and Performance P-Cores within the Processor could have something to do with it.

 

I entered the BIOS and disabled the E-Cores in my i9-14900K processor... All of my problems disappeared straight away and neither the PC or the Software has crashed once. It is not a long term solution, and I have since found that Intel are aware but have not yet issued any official statements while they investigate. But please check what processors you have if you encounter lots of random crashing!

 

I am sharing so that other frustrated AutoDesk Users do not go through the same painstaking problems when checking your processor make and model could point you to your problem straight away!

 

Please read this article regarding the CPUs:

We've been experiencing the same crashes & hanging as you mention with Inventor Pro 2025 & Vault Pro 2025 for months now with no solution in sight. Recently Autodesk suggested changing the CPU settings to single core which worked for the most part but causes hanging and an overactive fan when doing other stuff in Inventor. What's weird is that we ran these programs on these systems from when we purchased them new earlier this year around the same time as the 25 software was launched/installed and only started having problems in late June after a couple months running the software.

The problem with the Intel Core 13th and 14th Generation i5, i7, and i9 Processors has been identified as, if I'm well informed,  corrosion. I.e. a quality control issue. It should be remedied by a BIOS update, but if your pc is already affected by the problem, the BIOS update won't help. In that case, you need a replacement processor.

 

There is no fix for Intel’s crashing 13th and 14th Gen CPUs — any damage is permanent - The Verge

Unless your PCs/Laptops where off-line 100% of the time, some update (or combination of updates) were most likely the trigger. Which ones (not all updates are software or just the two you mention here) is something only you can identify and test sadly since your setup is not likely and truly identical to anyone else'.

Tried everything including bios updates along with drivers, software and a variety of other 'fixes'. We have 2 identical machines here that are a little over 6 months old with this problem. I guess were going back to Intel for some new processors or a refund. The annoying part is that the Autodesk techs dealing with our cases have constantly claimed Autodesk have not encountered this problem with any other users and repeatedly blame our data sets.

Read the room. It's not just the fact of the crashing, it's Autodesk's unwillingness to acknowledge there's a problem regardless of whether it's due to their product or others. If I can google the fault and get results, I'm pretty sure Autodesk can more easily search their own database for similar cases.

Reality check: we are all end users just like you, your need to get Autodesk to do "something" is not much anyone here can do about it. If you only wish to complain, Autodesk says they want you to do that here

yeah, good luck with that one.

 

Best wishes.

I had exactly the same issue, no problems whatsoever for 6 months and then it just happened out of the blue. AutoDesk also questioned my design files and processes, but I tried everything to clean it all up from scratch and it still happened.

 

HERE'S WHAT I DID TO FIX IT. And I don't care if it's not the proper way forward, it has worked, and has caused me no issue since I did it back in June.

 

Obviously, do this at your own risk. But enter your BIOS settings at startup (F12 for me). Yours will probably look different to mine..

 

In the Advanced settings and Tweaker part of my bios, I found Advanced CPU Settings (you are looking for the CPU settings so you can disable the Efficiency E-Cores)

I then set the number of E-Cores to Zero. Then I hit save and Exit, the machine re-booted, and I've never had a problem since.

Also, I talked extensively with a few tech guys on this whole topic, as I too was quick to point the finger at AutoDesk/Software Updates, etc, etc, but they seemed to think that Intel have rolled out this new Performance and Efficiency Core Technology with little consideration for large software developers, and therefore as time is going by everyone is starting to notice that the software can't perform properly. Gamers are noticing it massively, that's where I originally picked up on the potential issue, in a Gamers forum.

Thanks for the tip. I've heard this suggestion from others. I would have out IT dept. make these changes to be safe. However, I'm now hearing that there's a fault with the Intel(R) Core(TM) i9-14900K CPU. Word is that if the bios update wasn't applied in time there is probably permanent damage. Woulda been nice if Intel had notified buyers.

Yeah I always assumed there was going to be some damage, hence it taking 6 months to start showing any sign of an issue.

 

But like I say, I disabled those E-Cores and the problem went away. I just used the Intel Test tool suggested by @Simon_Weel above, and no problems reported, BUT it only tested the P-Cores as the e-Cores are disabled.. 

 

I spoke to the guy who built my PC months ago and he said he'd just change it under warranty whenever I was ready as there is clearly something wrong with the processors.

After my bios update I was good to go. I did make the mistake of updating all my drivers and screwed up my audio output and had to have customer support remote in to fix it... It has been working great since the update though, I wish I knew about this earlier

We got the CPU's in both our machines replaced under warranty from Intel. The motherboard on one machine was toasted too so had to be replaced. Fingers crossed this has solved the problems. My only issue was that Autodesk Support allegedly knew nothing of this fault with the i9 14900 chips and constantly blamed our data sets for months. I had to do my own investigation/research to come to the conclusion it was the chipset.
