Gamers Nexus did an update to their Enermax TR4 Liqtech video.....Not good.


I'm on my second Liqtech, it was replaced by Enermax when the first failed in less that a year. It was the second revision with RBG lights, but not the most recent revision which i got as an RMA. Hopefully this one will last. but for the video Im not holding out to much hope.

PS. They DID make me pay shipping to send the unit back.

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.


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.

I've seen one or two test results suggesting it could be as much as 9-10C cooler. So that's a nice amount of headroom for PBO to do its thing.

But then maybe those results are not completely accurate. I think it was gamers-nexus and one other review. But, also with PBO Im not sure if the testing is well designed. I did all my research nearly a year ago, so hard to remember.

Yes, its the MKII RGB version. Worked great at first. When it was working well I was very impressed with the performance. It got excellent results with both Vray and Corona bench.

I'm dealing with Enermax RMA in north america and they are sending out a replacement. Hopefully they have resolved the issue.

Been a while since i popped in for a read... Ill have to see what has been going on.

Just wanted to report that my Enermax TR4 360 AIO (gen 2-rev 1?) crapped out after about 7-8 months. So, i guess as expected.

Idle temps went from 35C to 57C. Both fans working fine so must be a pump/corrosion/gunk issue as has been reported many times.

With the new 'PBO system' its not really overclocking like it used to be, don't think there are any stability issues to worry about anymore. You just turn it on, and it will find the thermal capability of your cooling (enermax is good!) and take it up to that thermal limit safe and stable.

Honestly, if you don't turn on PBO you are just leaving money/power on the table. For the price you paid and the performance these chips are capable of getting an extra 15-20% out of your 2990WX is really not something you should pass up.

Check it out. You just get ryzen master and set the power limit, maybe 400-450 W. That's all. Thought you may need to point a fan at your VRM. I have a cheap ASUS 399-e board (got a deal) and since pointing a fan at the VRM I haven't had any issues running at 3.5-3.8 Ghz.

So i think i'm at a point with my prospective spec i'm happy with.
Anyone seeing any issues or bottlenecks? Id maybe look at faster ram if the price wasn't too much of an increase.


RM850X PSU
Samsung Evo 970 500GB boot drive
64GB Corsair Vengeance 2666mhz RAM
Threadripper 2990wx
Enermax Liqtech TR4 360mm
AORUS X399 Xtreme
RTX 2070
Fractal define R6 Case + 3x additional 140mm fans

1) Isn't 850W cutting it close for a 2990WX build???

The processor can draw 500W, add the GPU and other stuff and you must be pushing 800W or close already.  If you ever plan on adding a second GPU or anything you may not have enough juice. But then it all depends on if you are overclocking, which you should be for sure with the Enermax. I'm happy with the new Enermax revision, it can do consistent 3.8ghz with PBO @ 475W or so.

2) Also, this video scared me off the Aorus...

t

3) Ram speed does make a difference...if you can get faster ram then do.

How did someone get 37 secs bench time.  I have a 2990wx or to 4.0 with 32 go ram and I had a score of 1:12. What am I doing wrong?


I can get 37-39 seconds at 3.8ghz...3200 on memory.

You got 4 DIMM's??? Running quad channel memory? I noticed in my initial testing during the build that having 4 DIMMs (i.e. running quad channel) made a huge difference... Also ram speed makes a difference. Even going from 3200 to 3400 I got a second or two improvement, but can't get anything over 3200 stable.

Seems to slow down Corona benchmark by 2 seconds for me. Doesn't appear to have any impact on Vray benchmark. May still be a good idea to run, either way, to ensure that dynamic local mode is running as a permanent service. For 7-zip there is apparently some benefit.

Anyone else loses a second or two with corona bench?

Don't panic :- ). Common mosfets (even average quality ones) are rated for 120C. But lot of circuits around can start to deteroriate at roughly 105C. I see you often pass this peak.

VRM is often poorly cooled by even the best airflow, which is why people come up with all sorts of hacks by trying to point a fan directly onto the VRM. It makes a bit of chaos in overall airflow but can help the temps up to 20C.

Regarding my VRM temps I think I would have to measure it again at different voltages. I really didn't touch that PC at all since I gave it to Veronika. I think they never went above 80.

Definitely try to get some fan pointed at the VRMs. People with Aorus often do so and they have 10 phases for the CPU (versus 8), better heatsink, and most people in this thread under-volted.

Btw, if the noise from Enermax feels annoying, you can swap the native fans for Noctua Sterrox (NF-A12x25). I know it's not budget solution but they're state of art in terms of airflow/accoustics.

Okay, yes I have calmed down.

Running Corona the VRM seems to stay under 95C with a fan pointed at them. If Vray also stays under 100C (haven't tested yet) then I will likely keep the ROG STRIX board. Im also having an issue where the PC wont wake from sleep using AUS PBO, but if I use Ryzen-master it does. Ill see if i can get that fixed. If not i might consider another board.

Yes, Ill definitely change over to Noctua fans, as these Enermax ones are loud. That being said the Enermax gen.2 seems to be very good. Hopefully, they have worked out all the problems and it won't quickly fail like the Gen.1 versions.

VRM thermal issues... Time to rethink the ASUS ROG STRIX. Should have listened to Juraj.

I have received my Enermax TR4 Gen.2 360. This was an upgrade from my gen.1 280. It let me push the PBO to overclock a good bit further. However, after putting everything in the case (R6) I can see that the thermals on the VRM will be unsustainable.

Testing with prime-95 blend (which goes up and down in terms of stress) the VRM temps are touching 100C, with a 120mm fan 2 inches away blasting at 100%, shit. Running blend the temps get to 103, and are often in the high 80s to low 90s. FTT testing takes the temps to over 100C within 10 min, again with the same fan setup...crazy! Running corona the temp levels out at 94-95C around 30 min, don't think that's sustainable, is it? And its, loud, of course.

I'm attaching a graph, it shows a longer Blend run in prime 95, and then a short FFT run after a period to let everything cool off. It shows the problem very clearly. The performance is great, but the VRM is a disaster.

Juraj, I'm curious what the VRM thermals are like on the MEG? Now that I have a better AIO the VRM are showing themselves to be the weak link. I can still return the ASUS, and given the cash I already have in this system it seems a few hundred more for stability and maximized performance would be worth the tradeoff.

Damnit, I guess its time to tear this thing apart for now.

Is it overkill if i dont plan on overclocking?

Juraj said it...but think of it this way.

Its not really overclocking anymore....these new CPUs are capable of automatic all core turbo boost. Overclocking used to be a project in itself, now its a feature.

  If you don't use it you are just leaving performance on the table, rotting fruit on the vine. The real question is, how much do you want to spend on cooling, and that breaks down into a performance/noise/cost trade-off.

In other words....just do it!

Are there any better cooling solutions i should be considering?

It's been mentioned here a few times... The Enermax Liqhtec tr4 gen.2

You can see the Gen.1 performance advantage here. The issue was that gen.1 had all kind of problems that would lead to failure...
https://www.gamersnexus.net/guides/3089-threadripper-cooler-comparison-full-coverage-liquid-vs-air

Supposedly, the current (there were maybe even problems with the first batch of gen.2) Liqtech TR4's have all the issues resolved. I'm taking the gamble as the performance is clearly good. I have a gen.1 280 that is still working fine after 9months and its good stuff. But I will RMA it for a new Gen.2 just to be safe.

I 'm  using Noctua NH u14s with double mounted fan to cool my system.
I' m curious about other idle and "loaded" temps with  solutions like wraithripper, enermax, or custom.

my Tdies are :  idle 28-29 C  and loaded 48-49 C . Room temp is 20 C.

Have you turned on PBO, AMD's automatic overclocking?

If your temps aren't 68C at Load then you are leaving a good deal of performance on the table. PBO should overclock your CPU until it hits its thermal limit at 68C. On ASUS boards this feature is called performance enhancement in the BIOS. Not sure what its called for other boards. But maybe you are holding back for noise, or VRM overheat?

There are comparisons out there. Google around. From what I saw Wraith and Noctua are neck and neck, the silver arrow is a bit better, and Enermax is the winner, maybe by 6-10C over Noctua. But there have been lots of problems with the Liqtech rev.1, huge fail rate, and some leaking. Rev.2 maybe be better, but the jury is still out.

On a personal note, I have been waiting like 5 business days for a proper RMA response from Enermax. Just terrible. Unfortunately, they are the only game in town right now on the AIO side.

First things first. Question, is everyone respecting the 68C thermal limit with their manual clocks? I haven't seen anyone recommend going above it. Also, are people undervolting their PBO? Im on ASUS and using the offset to under volt the PBO with - 0.1 CV.


Okay, got my 'cheap' setup going.

ROG Strix 399-e
2990wx
64GB Corsair LP 3200
Enermax Tr4 280 (I know, I know. Actually got it used from Kijiji, its now 9 months old and no issues. Ill RMA it and get the gen 2 asap)
Evo 970

Testing on an open-air bench, with a Quadro 600 until its time to swap out as my main workstation.

For now, can get 37 seconds on Corona Bench and 23-24 on Vray. Playing with both PBO and Manual clock. With PBO the board Throttles at 68C of course and ends up dropping from the initial 3.8 (the max all core PBO from a cool starting point) to anywhere from 3.5-2.9 depending on the task. Corona and Vray benchmarks tend to average around 3.4-3.25. Prime 95 FFT test sends it right down to 2.9-3.0, while the blend test results in 3.4-3.5.  I can get similar performance from a manual OC, but it runs a bit hotter than the 68C recommended, requiring 1.145 CV to maintain a stable-ish 3.7. For now, I'll take the PBO result and be happy with that.

Some observations...
-Strix board seems to be doing fine so far. VRM has gone up to 76C (open bench of course). Power delivery has been adequate for what I'm doing. It's definitely not a limiting factor at this level of Performance/thermal limit. That being said, I need to do longer term testing. I remember seeing someone with a MEG board say they were getting stable 3.8 Manual with 1.1 CV. definitely need much more here, 1.14-1.15 to get close to stable, and then my cooling becomes an issue..

- Enermax is doing a decent job. hope it doesn't explode. When I RMA the gen 1 for gen 2 ill see if I can upgrade to 360.

- I like this new type of Overclocking. The thermal limit is set and the MOBO does all the work. That's a step forward. Long as the board isn't shit (and mine might be) if you want better performance, just buy better cooling.
