Wasnt that new 16c with 80% of 2990wx performance seriously overclocked with like 1.45Vcore ? I dont think thats sometihng you would like to run 24/7.

That said, could be anything from heatsink seating to fan profiles, to software used to monitor temperature readings (super inaccurate) to what package is being run. Cinebench and Blender are less intense than Corona.

Yea i noticed better temps and voltage management with latest bios from 03/2019 also better memory compatibility (mostly overclocking)


Sorry for interrupting your Mac related discussion guys but i noticed weird thing today.

Having default XMP enabled (3000/14) with stock CPU clock.

Corona : 41s / Cores capped at 3.175ghz
Cinebench : 11 000pts

XMP enabled with just memory multiplier changed to 29.33
Corona : 40s / Cores capped at 3.4 Ghz
Cinebench : 11 600pt

Any idea whats going on here ?

I'm happy to report that it's all going well so far after 1 day. The RAM is clocking in at 3000, and I'm seeing average temperatures of around 68 degrees under full load.

68 under load ? Thats a lot imo on default clock/voltage. On my totally stock BIOS settings im getting (without undervolting) 58C with NS14 ( single fan ).

I agree with you there fully Nox3d. There is no reason to avoid genres, themes, looks, even cliches just because they were done before or popularized by someone else. There is always space for another Farnsworth House :- ).

First, it's how we all learn, we emulate what we find beautiful and speaks to us. As long as it's not plagiarization, it's new for person who made it. And just because it's common to you, it's not to someone else. Given there's a billions of us, reaching for originality above all is futile attempt, sometimes bordering on pretentious. You can all proclaim photography to be dead with approach like this, which is hardly the case.

I am also tired of backhanded "compliments" that speak more about commenter than the author of artwork, like the endless "another XYZ? (more boring archviz?uuh...). For those who don't find the artwork interesting, find another one to comment that's more to your liking. I don't go around the street telling people I don't like their commuting family cars, why don't they buy more unique sport cars ? Well that's lot of stupid analogies from me but you get the point. Ignore if you don't enjoy the genre or feel the need to nitpick irrelevant crap.

First of all, this is forum and not street. People are not walking around and be like "Hi, this is my new family car, what do you think". And comparing cars to art , uh ? How you can compare something you buy with something you create.

He posted his work here and expecting some feedback. I told him that his work is very nice but im having problem to enjoy stuff like this. Alex did movie which we can consider as milestone in archviz industry and in one decade, no one even came close to it in terms of quality (not just photorealism but overall craftmanship). Its like trying to mimick Queen or Beatles.

Anyway, there is so much of quality projects floating around that its very hard to be unique these days. Mimicking other`s work for studying pruposes - okay, but its pretty clear that goal was to get as close as possible to his inspiration : with color balance, camera movement, DOF and basically whole composition. You can copy or imitate a lot of stuff , if its common, no one even notice. There is tons of projects similiar to each other but there are certain things in life which set the bar and everything similiar to it will be considered as "knock off". And if we are talking about archviz, Roman`s movie is one of those things.

And also, i dont understand this "if you dont like it, do not comment" philosophy. Are we gonna cuddle with each other ? Imagine music or movie industry without critics. I do miss those old times when everyone tried to be unique. Just open Behance and everything looks like it was made by one author. And because of mentality you are describing in your post, majority of archviz looks like a copy pasta. And about what genre you are talking about ? About Alex Roman`s genre vs rest of the archviz ? As i said, if i open Behance i dont see any genre. And im sure you know what im talking about.

He even used almost same font for the final caption, cmon.

Looks very nice but im kinda having problem to enjoy Roman`s knockoffs. No offens tho.

I`ll play with corona benchmark if there is difference between 2133 and 3000, im curious as well. Will post results here.

Regarding temps : if i undervolt it by -0,125mv im losing like 200 points in CB (11 200 vs 11 450) but i can sit on 50C with 3000/14 on memory, which is awesome.
Totally silent PC and all just with 1x Noctua fan.

You could try manually inputting all the timings and clock for memory without having XMP set it for you (it sets all sort of other stuff as well, potentially overriding your overclock/power settings).

AVX code is still affecting AMD architecture in Corona, so there will never be absolute parity with something like Cinebench or Vray, I've asked devs multiple times about this and there is no way they can get rid of it due to their compiler.
3.3-3.4 +/- is the correct all-core speed roughly for 250W ceiling/default settings.

I had all sorts of odd shanenigans where the Spectre hot-fixes bundled with regular Windows updates (every 3 months +/-) would cap the 2990WX clock at 3.0 for 250W all-core due to affecting power settings. But outside of that, no issue with memory clock/timings. This sounds like XMP-profile/AVX-turbo issue.

Yea, shortly after my post i set frequency to 2933 manually and put 14/14/14/34 while voltage remained at auto (1.35) and im getting 1480-1500 points now, so you are right, its something wrong with XMP profile. PPT is hitting 100% again while rendering in Corona but at least, CB score is same. I think i hit ceiling with memory and stock CPU clock.

 Also noticed that if i set offset to -0.125mv like before, it cuts my score by 200 points which wasnt the case before with old memory set. Undervolting wasnt affecting performance but now it does. However, temp is sitting at 58-59C now which is okay i guess (was 49-51 with undervolting).

My decision now is all about silent + cooler PC with little performance drop vs stock voltage, little perfomance boost but noisy case. 58-59C is that stupid treshold where fans are starting to blow up quite a lot. Or even setting everything to default, i dont really feel any performance gain. At 2133mhz clock, CPU runs cooler and i cant really see any difference between 3000 and 2133 except aida benchmark

As i said in my previous post, my CB score didnt changed BUT i noticed that with new RAM modules, clock is capped at 3.0 while rendering. Honestly, i dont know if i had same situation with my old mem set but as far as i know, this cpu can hit 3.3-3.4 at stock speeds so i was curious whats happening. Went to bios, turned off XMP profile and boom, cores are peaking up to 3.4 and my CB score (R20) went from 10 900 to 11 440. Thats rougly 5% difference. 5% is like +- 2.5-3min difference while doing 1hour render. Doesnt matter much for me but im curious if its worth to run on 3000mhz/cl14 then if only noticable difference is lower CB score.

Im not into overclocking that much, i have basic knowledge but any ideas whats happening ? They are running now at 2133/CL15. If i enable XMP back, cores are capped at 3.0 again. Also, while rendering, my PPT is at 100% limit (250w). I think it wasnt red before but again, wasnt paying that much attention to it before.

EDIT : Apparently, only Cinebench is hitting 100% PPT while peak speed is always 3.3ghz. I can hit 3.4ghz peak speed while rendering one of my scenes and PPT is at 88% in corona.  If i enable XMP its back on 3.0ghz max and PPT is 100% again even in Corona.

This is kinda weird if you ask me.

Just bought F4-3000C14Q-64GVK (b-die) for 400e (bazos).

They worked out straight away with just with XMP enabled and  they are running at 3000/14. I wasnt able to OC my old set, it was running at 2666/16 even with CL15 specs.

There is zero difference compared to my old 32GB set (2666/15) in CB R20 and Corona benchmark is slightly faster (47s vs 43s).

Aida screens if someone is interested

Going to get set of 64gb ram and as far as i know, Zen works "best" with b-die .

Its worth throwing 300eur more for 3200 CL14 just solely for 3ds max and rendering purposes compared to 3200 CL16 ? Did some research but most of it is comparison in games.

btw : found B-die finder

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?

Post your pc specs here

For slovak / czech speakers

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?

Corona benchmark is same for me but in cinebench i gained like 100-150 points.

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.

There is literally zero benefits running two fans on NH14 (pull - push). I noticed more noise while having 2 fans running and i did 2x 4hr test with 1 and 2 fans and difference was 1C.
Problem is that its single heatsink design. Hope they will release NH15 in future.

I was playing with my system a bit. I dont want to OC it since its my 24/7 machine for everything /i have xeon renderfarm for long tasks/.

So i decided to undervolt my 2990wx and im on stable -0.125mv. Cinebench gives me 5122 points so there is no power loss. Aida64 hits 52-54C /56C peak/, Corona never pushes over 52C and volatage is fluctating from 0.98x to 1.08xV.

Im using only 2 fans atm - 1x NHU14 and 1x case fan. I can barely hear my PC now even at full load. Im so damn impressed. I think there is still some room to go even lower.

loaded rendering 67 c

Keep eye on the temps, it will start to power throttle at 67,8C. During summer definitely.
