Yup - the latest windows update Maru posted above seems to solve everything!  Ive been testing for an hour now in different scenes and both interactive and normal rendering works great!

No overclocking here whatsoever. I tried enabling expo before but the computer wouldnt even boot. The problems seems to be me having 4 sticks of ram. It seems to be a better idea to use only two sticks if you want to run them at faster speeds.

Ive been away for a couple of weeks, but the latest win11 update seems to have fixed everything for me.  I can run Bitdefender too and render without problems.  For me the main problem was definitely a windows-issue.

Perhaps you could add 3dsmax.exe as an exception to your antivirus?
It's really interesting to hear about disabling core parking bringing some improvement. It would be great if other users could try it and share their outcomes.

Already added 3dsmax.exe as an exception but didnt seem to make much difference.  Will make some more tests when I have the time.

Thank you Maru!

Havent tried all of the suggestions yet, but disabling core parking made a huge difference here.  I have to run more tests, but I think I could both render and use interactive render without much problems after that!  Then I reinstalled Bitdefender and now Im having problems with the interactive renderer again... but im guessing thats a problem they have to solve and nothing you can do much about. Normal rendering seems to work fine even with bitdefender installed now.

the "disable core isolation" option made everything worse here so not using that.

So - part of my problem was caused by Bitdefender antivirus. After uninstalling it I can actually render without freezing, and working in other programs at the same time works as well!  I dont know yet if it renders as fast as it should, but at least it renders.

However - the freezing is still there when using interactive render. It seems to work for a little while but then gets more and more frozen to the point where adjusting anything in the scene is impossible.

The problem is also still there in corona benchmark - it doesnt freeze like the interactive render but it stutters (like 1 second freezes) which affects the score.  Getting varying and too low scores. Ran it 3 times today and got from 11500000 to 13500000. All too low for this cpu.

Not a solution to the original problem in this thread , but if your normal renders freeze and you use Bitdefender - try uninstalling it.

Thank you Marcin for your time and trying to fix the problem today!

For you others with this problem - do you use Bitdefender for antivirus?  And is it by any chance provided remotely using some sort of "managed antivirus solution".  The next thing for me to check is to disable my managed antivirus and see if it makes a difference. (but since its handled remotely I dont know how to shut it down locally - will try tomorrow...)  I know some people have been having problems with bitdefender slowing down certain programs. Havent read of any problems with corona though and have been using bitdefender on my old computer without problems so its a longshot, but maybe you could try and see if It makes a difference?

Or maybe its 24h2 causing it after all. Like Quest I havent found a way to install 23h2 to check.

Corona team?

I just bought a month license for Vray to check if it also freezes. I think the load on the cpu would be about as maxed out using vray as using corona?

Vray has no problems with freezing, and I can use photoshop freely at the same time.  I made a scene with only two simple materials (basic white wall and glass) and no textures, and tried it in both corona and Vray.  Corona freezes and stutters, vray does not.  Both push the cpu to about 88 degrees.

Most of the time corona freezes I can still move the cursor, but cant click anything. Sometimes the cursor also freezes in place.

So to recap.  Latest windows 24h2, 3dsmax 2024, corona 12 update1 hotfix1, motherboard msi mag b650 tomahawk, 4x32 gb ram running 3600 MT/s no expo, Ryzen 9 9950x no overclocking.

I can also run cpu stresstests like OCCT that push the cpu to its max without problems.  But rendering or using interactive render in corona breaks my computer completely.

Do you need more info from me - ask. I very much want this issue solved asap.

Hey Corona team - have you been able to reproduce the freezing/stuttering on 9950x and win11 24h2?
My new workstation is just a very expensive pile of rubbish until this gets fixed :( Would be great if you could look into this and figure out if the problem is in coronas code or in Windows. Or whatever else might be causing the issue.

Ok Im back...

Just got the computer back with better cooling and now it stays around 85-87 degrees, but it still freezes during rendering!  Before it seemed to only freeze/stutter when reaching around 95 degrees but now it freezes at lower temps.  Impossible to work in any other program during normal rendering, and when I tried interactive rendering it froze so bad I had to close max from the task manager.

I just tried the corona benchmark again.  Ran it 3 times (just pushing "restart") and it gave me 3 differens scores. First time 13 500 000, second 12 500 000 and third 14 400 000.  The first two are too low, and i really dont see why it gives different results. No other major programs open at the time and no changes between the three runs.

Not using EXPO for the ram.  I have 4x32 GB running at 3600 MT/s.  Im on win 11 24H2.  9950x (not overclocked).  Corona 12 update1 hotfix1

What is going on??

Im willing to try to roll back to win11 23h2 and see if it works better. Is it possible to roll back without having to reinstall everything on the computer?

Ok - thanks. If the difference is that small its not really an issue...

Hardware / how much difference does the ram speed do?
« on: 2025-01-27, 20:10:42 »
Hi!

Just bought a brand new 9950x workstation. I asked for 128gb of ram, but didnt specify more than that since im no expert.  I can now see that the store put in 4x32gb of fast DDR5 memory 6000 Mhz, but its only running at 3600 Mhz according to the bios.  I tried enabling EXPO in the bios but that simply caused the computer not to boot at all.  After a bit of googeling I found out that its difficult, maybe impossible, to run 4 sticks of ram at that speed for some reason.  But if they had used 2x64 GB they should have been able to run them at 5000-6000 Mhz.  A rookie mistake it seems.
So - before I start bugging the store about this asking them to change it to 2x64gb instead - how much will the faster ram affect my working in max, and or my rendertimes? Or will it affect anything else?   I have in the past only bothered with having enough ram to avoid crashes, never thought much about the speeds.

Thanks in advance,
K

95C is the Tjmax of a 9950X so it definitely shouldn't be that hot. If removing your PC case panel and lowering the CPU temperature helps, then cooling is definitely the culprit.
Software cannot overheat a CPU. The cooling has to be efficient enough to cool down a CPU even under 100% load (which is what Corona does).

It seems that multiple people here are experiencing multiple different problems.

Yeah sorry, mine is probably not related to the original issue here. I brought the computer back to the store today and they ran some stresstest of the cpu and the temp went up towards 95 after only a couple of minutes, and the temp dropped quickly when they removed the side of the computer.  I guess they will try to get the temp under control with better fans/cooling and we ll see what happens... 
I thought it was strange that I could run the corona benchmark without problems, but maybe it just didnt last long enough for the temperature to spike...

It is normal for the processor to be at 95 degrees. It works at the same temperature for me too. There is no problem with rendering during IR, but the system freezes. Sometimes the system shuts down completely. When it is turned off, the temperature is often around 80 degrees. If you use the bios at default setting you will see the difference.
The bios are at default settings. Dont think its good for the processor to be at 95 degrees.  If it gets hotter than 95 I think it starts to throttle which I believe is whats causing the freezing problems for me.  Again - by removing the side of the computer it lowered the temp by a couple of degrees and all the freezing/problems went away.  Not sure if this is connected to your problem or not, but the symptoms are similar.  I will return the computer to the store tomorrow so they can take a look at the cooling. Maybe they made a mistake when they put it together.
However, the problem only occurs when rendering corona in max. I have the latest hotfix installed. Latest win11 version. When running the corona benchmark there is no problem with temp or freezing, so maybe there is a problem with corona for max?

I think I have the same problem with my new 9950X.  But in my case the interactive rendering works almost ok, it lags but doesnt freeze. Its the normal rendering that doesnt work at all.  Max freezes for 10-30 seconds then responds for a few seconds before freezing again. Impossible to do anything else on the computer.
I just made a test removing the side of the computer and I could render for 10 min without freezing, so I guess the problem in my case is that the cpu gets too hot. With the computer case closed it goes to 95 degrees in a few minutes when rendering and freezes almost instantly.

I downloaded the corona benchmark and it ran without problems. Its rendering in max that doesnt work. Cant say if this is a problem just with my cpu cooling or if there is something in corona making the cpu go crazy.
