Yeah, thanx for the advice Juraj!

I’ll post some photos and benchmarks when they’re ready (~2 weeks maybe)
I know it maybe seems like rushing but really I need the PC’s now and it’ll probably be 2020 by the time threadripper 3 is out with all the mobos supporting it and all the initial bugs and bios ironed out.. till we know what’s what.

Totally excited!

When you need something now, it stands to buy it :- ).

Rather true what you mentioned about initial bugs...I almost forgot what a hassle that was..

 New CPU's equals new questions (for you Juraj I'm affraid) ;)  I didn't think about matching mobo's, cpu's and dimm's at all which is unwise. Buying and finding right parts will take weeks (if I'm lucky enough) so in best case scenario new WS will come to life in january/february.....and correct me if I'm wrong but it means 5 months of pointless waiting.

Hi all,
I am about to buy in the next week my first computer. I have never build anyone before but I will ask for some help to some friends and IT team from my company.
Several colleagues told me to read Juraj Talcik threads to understand and have a better knowledge before buying anything.
I am a little concerned because many people posted they are problems with Max crashing several times after moving to AMD Threadripper, so I will like to know if you can give me some feedback of your experience with it. Is it just because people might not have configured their PC properly or you do have some issues having an AMD working with MAX.

I have seen the configuration you suggested in other thread:
 1.AMD Ryzen Threadripper 2990WX 32-Core Socket TR4 3.0GHz Unlocked CPU Processor
 2.MSI MEG X399 Creation TR4 E-ATX Motherboard
 3.8 x Corsair Vengeance LPX 16GB (1x 16GB) DDR4 3000MHz
 4.EVGA GeForce GTX 1080 Ti SC Black Edition GAMING, 11G-P4-6393-KR, 11GB GDDR5X, iCX Cooler & LED
 5.2xNoctua 120mm NF-A15 HS-PWM chromax.black.swap 1500RPM Fan
 6.Samsung 970 EVO Plus 1TB
 7.Seasonic SSR-750PD 750W PRIME 80+ Platinum Fully Modular Power Supply
 8.Fractal Design Define R6

I have see you recommended to buy as well:
EKWB loop, all parts.

What exactly I need from those and where to get them from?

The PC configuration would be around 8K approx.
Are they AMD Processors better for corona than Intel?
Is it easy to configure and set up the PC?

Thank you so much everyone for all your help

Here we go , multiple options with "TR3"

https://www.techpowerup.com/258739/amd-readies-three-hedt-chipsets-trx40-trx80-and-wrx80

It looks like next "teaser" from amd to me. I'm going to enjoy my tea and wait for official announcements and price tags, then we'll talk. :)

Hi, I need a help over threadipper 2990wx and corona.

I have a threadipper 2990wx cpu with asus prime x399 a motherboard+ RTX 2070 + GTX 1070 + 56 gb ram currently Installed.

What my problem is, Whenever I am rendering anything. Even a very simple scene with few objects and hdri. Corona and 3dsmax starts lagging like a lot. It gets impossible to work on it.
Here is a link to a video which I made (https://www.dropbox.com/s/3xdnfopmk2qptwe/corona%20bug.mp4?dl=0)

So far, I have tried many solutions such as:
1)Limiting core usage on corona.
2) Installing corona 3/corona 4 and even corona 5 daily build.
3) Installing 3dsmax 2017, 2018, 2019 even 2020

As I go up on versions, the problem becomes worse. For only lagging to crashing whole 3dsmax scene.

As you can see in the video, the scene file is very basic. In task manager you can see...ram is not full....even graphics card using 1 to 2% usage. Everything seems to work normal.
I have Intel 6900k and AMD 1800x too and In that system, corona runs very smooth. Both are octa-core system. But in amd 2990wx, corona seems like it is not supporting the processor at all.
I have done corona, vray, Indigo render stress test. Everything stress test go flawless.

As far as I have tried debugging, I think this problem is related to corona not being able to handle the SMT of AMD. with that many cores, corona becomes unstable.(I do not know for sure)

I would appreciate any help on this issue.

Hi. Not an expert, but from what I've read, it's likely caused by your motherboard model. It's not build well for the 32 core chip :(

I have done benchmarking with vray and Indigo benchmark and done stress testing too and monitored temps of the motherboard as well as cpu. Everything seems normal to me. So, is it that asus prime x399 is not compatible to run corona? Other applications seems run fine and smooth. Anyway, which motherboard would you suggest for 2990wx? I might give it a try.

Hi. Take a look at post #429 in this thread. It's not about "compatibility with Corona". It's more about being build for extreme 32 core workload.

Hope it helps

Its not your MOBO!

I have the ASUS ROG STRIX X399-E. Also same foundation as Prime and Zenith EXtreme MOBO.  When people say its not built for 2990wx, what they are (or should be) referring to is total power delivery, i.e. VRM. Even with ROG STRIX X399-E I can run my 2990wx with no problems at 3.3-3.6 across all cores as long as I cool the VRM directly with a fan.

If you have poor viewport performance in 3ds max this is clearly not a product of your MOBO, unless it is totally F-ed for some reason.

Few ideas.

1) You want to be running quad channel ram. That means using 4 or 8 sticks. Not sure how you are getting to 56, but if you aren't running 4 or 8 sticks then you are cheating your self. Makes a huge difference for rendering. Quad channel memory. Fix that shit. 4 or 8 sticks of the same type/model of ram. Nothing else.

2) Try trouble shooting your video cards. You have mixed gen cards. Try pulling one and testing, then pulling the other. See if anything changes.

3) Update gpu drivers, or move to last known stable drivers for 3ds max.

4) Idea 4 is not a fun one. If I were you and 1, 2 & 3 dont solve your problem then I would be going for a full clean install of windows 10. Install max first and start testing from the get go. Install plug-ins, apps, and keep testing in between, see if and where it goes wrong. Maybe your install is dirty, or got messed up.

Just my two cents.

Hi, I have finally been able to debug the issue. The issue was caused by a windows 10 feature called control flow guard. You can read all about here. https://www.thewindowsclub.com/control-flow-guard-windows

After I turned this feature off in windows 10. The performance of corona+3dsmax all improved all together with no lag whatsoever.

If someone ever experience performance lag issue in future, I would recommend turning this feature off on windows 10.

Also, you can get this small piece of software if you have 2990wx for CPU optimization.

Thanks to Vladimir for pointing this out.

You don't need to go full custom water loop, I did it because I like both performance and super silence at same time, but overall I am not sure it's worth the price premium for most.
Buy Noctua UH-14S TR4, and in few months, when NH-D15 TR4 will come out for Threadripper platform, sell the U14 and replace it with the much stronger D15.

Yup, this has been issue since 3dsMax 2017+ for some reason. I never had it in 2016 which I use, and I have zero issue with the 2990WX performance and 3dsMax, Corona, or anything else.
