Honestly I'm not sure if these cheaper coolers are "that bad" to begin with in terms of reliability. From my understanding the biggest issue can pretty much only be the fan itself - which on most of the coolers I think you can replace anyway. The other issues I can't help but think are pretty rare like the liquid inside the heat pipes evaporating... But someone can correct me if I'm wrong :)

That said, I do always buy Noctua just in case because I am under the impression they double check things, have multiple proper mounts for multiple sockets etc...

Oh and I guess I should mention that I do also have a 9654 Epyc for which there's like only 2 air coolers out there that aren't jet engines - and there I opted for a completely unknown firm but hey, it works fantastic on a 400W CPU for half a year now already. Pleasantly surprised to say the least.

Made me curious, what was the "unknown firm"? :) Also, what cases are you running and are you happy with the noise?

ps can you please provide a link to the reddit thread you were talking about?

It's this one: https://www.reddit.com/r/overclocking/comments/1i1cmwi/9950x_with_192gb_4x48gb_at_expo_6000cl30_stable/

64gb pr stick on sounds crazy for am5, but maybe worth waiting a couple of months to see what happens? But then again, we can always juuust wait a bit longer for something new and better. My old xeon at home (which this build will replace) scores only 5mil rays in the corona benchmark, and running on 64gb 3200mhz ram :D So no matter what, I will feel the upgrade. Last night I was tempted to just go with a 9900x and 2x48gb and save a lot of money and probably headache. The 9900x is almost half price of the 9950x3d and I would still get over 2x performance compared to my old system. With ai upscaling, I don't see a huge need to be able to render out more than 3-4k native and for that I think the 9900x might be enough and use the saved money to save up for a better gpu. End of day it's only for the occasional freelance job, but I can feel the old pc at home is troubled + win10 updates will end this year and it so old its not allowed to upgrade. Curious if the 9000 series will have smoother IR and material editor performance than the 3990x threadrippers we use at work.

cheers marchik, good insight! Should (in theory) any 6000mhz cl 30 48gb modules work in a 4x configuration? If having to lower ram speeds as you did, does that have a real life performance slow down in production work or is it just for gamers? (I don't care about the gaming performance).

Reason I ask is that the modules I saw by other reddit user who managed to run 4x48gb at 6000mhz, is currently sold out.

Seems like it does perform better anyway:

One other thing to consider when looking at coolers is the reliability & warranty.

Yes some of the newer brands of coolers may be cheaper but what is their failure rate like? How well do they handle incredibly high loads?

Personally I'd rather spend more on a Noctua, or even more on a AIO cooler from Corsair/Coolermaster etc. and be safe in the knowledge that it isn't going to suddenly crap out on me, reducing productivity while I wait for a replacement.

Good point. I will probably go for the new G2 noctua. I've had zeo issues with my old one that's around 8 years old now. The thought of having a pump die or leak from an AIO system is enough to put me off them.

I recently bought my 9950x.

After some tests (testing with 4 of my scenes), the improvement over the 7950x is 16-18%.
(Scene 1: 16.63% improvement
Scene 2: 17.71% improvement
Scene 3: 22.32% improvement
Scene 4: 16.44% improvement)

BUT, I didn't have the 7950x overclocked because the temps were already high at stock.
AMD claims the 9950x is more efficient so I enabled PBO, which led to a higher difference.

Hope this helps.

How is life with the 9950x so far Lupaz? I'm considering to build a new system with that cpu. What amount of ram and motherboard are you using?

cheers Maru, I'm pretty sure I read one of the win11 updates some weeks ago had fixed these performance issues. But maybe you are right and I should search a bit more for people to confirm this :)

Hardware / 9950x3d in a "silent" build? Case choices

« on: 2025-03-17, 12:35:05 »

I want to replace my old xeon machine at home with a 9950x or 9950x3d (the price difference doesn't bother me, I just want the fastest one and the 3x version seems to perform better in corona render benchmarks I've found + single core speeds seem to be same too.

I found a reddit guy who managed to run 192gb ram with the 9950x and a msi tomahawk x870 board stable at good speed (6000mhz). So that's what I think to copy.

Now, usually I'd just stick with my good old noctua NH-DH15 cooler, but after seeing some tests and reviews (including the new G2 noctua cooler), I'm blown away that coolers 1/3rd of the Noctua price is actually performing almost just as nice.

Now, I have most of the hardware lined up on my list, but the case is a tough one. Ideally I just want a simple black box, no fancy rgb etc. I couldn't care less. But I want it to have some sound dampening qualities and maybe have space for a new big GPU sometime in the future.

Many of the "silent" cases will however restrict airflow and there seems to be a consensus online that it's better to go with a case focused on airflow and then get good fans that can run slower.

I don't want to OC or anything, just have a fast stable rig with as little noise as possible. Will reuse my 4060ti gpu.

Any recommendations?

[Max] I need help! / .rcs pointcloud and corona?

« on: 2025-03-13, 16:41:25 »

Gotten some .rcs pointclouds for a project. Opens nicely in max via Create->pointcloud and then loading the files. But it doesn't seem like Corona can render this type of object? Tried some searching in the forum and saw it was added as a feature request in 2017, but I guess still not possible?

Have anyone found a work around?

[Max] I need help! / Re: Node to rotate a texture?

« on: 2025-03-03, 20:15:37 »

I have reported this as a feature request at https://chaoscorona.ideas.aha.io/ideas/CMAX-I-143
Note: it is currently invisible since it's in "new" status and pending Tom's the Product Manager's review.
If you have any comments or would like me to change the description/title, please let me know. It was kind of hard for me to come up with a meaningful title.

Thanks Maru, fingers crossed it passes the review ;)

Hardware / Re: old threadrippers and win11 upgrade?

« on: 2025-02-24, 15:23:11 »

The thing is 3ds Max sometimes switches the "view to render" internally and this results in an attempt to render a non-existent/broken viewport. The idea here is to disable the lock feature, make sure that the correct view is selected, and lock it again. I am just sharing it as it has recently helped with an identical issue.

ahh perfect, thank you for clarifying Maru. Will try and remember this fix. I have archived the scene and will upload now.

While it archived I downloaded Corona 12 update 1 HF1 just to see if it would change anything. Installed. Rebooted and started max and the scene. I clicked IR as the first thing after scene load. It opened VFB and seemed to start loading (memory consumption was going up steadily), but before render started, it instant crashed.

So will include that max log and mini dmp in the archive scene ticket. Just be aware that the archived scene is with Corona 12 HF1 and not "Update 1 HF1".

I was dealing with an identical case today (or maybe the report/scene originally came from you? :) )
The solution was the good old "lock icon in Render Setup", so:
- Press Alt+W to show all viewports
- Open Render Setup
- Click on the viewport you want to render
- Lock the small lock icon at the top of the Render Setup window
- Then render
I hope this helps!

I haven't submitted the scene, but it seems to still be an issue with the scene. On first scene load, it will not render. Just shows the VFB with the corona icon smiley (I'm using old interface) turned just a little bit. But nothing going on in stats, the render button is grayed out and "stop" is blue as it usually is when rendering. I noticed that the usual max pop up with "loading geometry" etc wasn't showing. I shut down max. This will keep happening, so I have to shut down max. Start it again, and then it works.

The icon lock is always on in my settings and haven't changed since pre the win 11 update, so don't think that is the case.

Interactive rendering + slate material editor open is a horrible experience on this CPU still (3990x). Even viewport is very laggy. Had hoped win11 would have fixed something.

I will do an archive and send to you to see if you can reproduce.

Thanks for the feedback guys. If it were up to me, I would 100% stay on windows 10, but it's a company IT policy that all must be on win 11 before summer.

I managed to turn the TPM 2.0 on via BIOS. Didn't notice anything changed when I got into windows and corona was working fine. I was then asked by IT to reboot so their win 11 auto upgrade would kick in.

It updated to win11 without issues (just took quite a while). However, the scene I was working on yesterday (pre win11), would not render. VFB starts up, but the corona smiley is not turning and nothing is happening under "stats" either. I tried doing IR, but then max crashed (asking if i wanted to autobackup).

Before this I got an openCL warning from max that asked me to update my GPU driver (makes sense, so I did that and haven't gotten the warning this time).

An empty scene with a box and corona sun + sky renders without issue.

I loaded max and the scene once again, isolated only 1 object, tried to render that and after some time it rendered. Then I unhide rest of scene and all rendered fine. Very odd. Will have to keep an eye on this.

"Loading Corona Assets" are also taking a few minutes on scene load - I thought this was fixed long ago? (I'm on v12 hotfix1)

Thank god I'm not on a tight project deadline right now :)
