Wow, great thing! I tried and downvolted 1080 to 900mV.
Firestrike ultra stress test:
  • at default settings: 55C and ~1750 frequency at the end, 28.11 avg fps
  • undervolted: 52C and ~1830 freq at the end, 28.41 avg fps
You may had taken the power consumption of the GPU ?

Good news I have seen for CPU. The New Ryzen 9 3900 with a TDP of 65W for 12 cores / 24 threads !!

I need to get more into that !!
My first testing session this morning on Firestrike extreme / 22C ambiant / 1080FTW

1/ Standard configuration
Furmark 9570 points
Max GPU power is 199W -Average 138W
Average voltage 0.91V
Average freq 1074Mhz

2/ MSI afterburner with clock at 1700Mhz (below standard curves)
Furmark 9130 points
Max GPU power is 168W -Average 111W
Average voltage 0.86V
Average freq 1074Mhz

--> I need to check why in standard mode frequency is lower than when I try to downclock ...
--> I will go even below & complete with CPU.
--> I tried to use EVGA software. I was just able to decrease performance at same power ;)

No, i will check it then i'll try to optimize it more.


Since AMD boost to around same clock for x and non-x models, isn't this TDP too low compared to max power consumption?...
at 28:14:
I hope we will keep the same range of TDP increase. Maybe a 40 more would keep us below 100W. That would be really nice for 24 threads.
The TDP is a difficult number to play with and may be only realistic at stock clock.

I will do and post soon before/after undervolting results.What I remember from my previous tests is that my 1080Ti reference, was boosting itself to 1870MHz, but it was fluctuating a lot. Consumption was 240-250 Watts. At 1.1 V - also fluctuating. Don't remember the temps, but the difference was huge. After setting up the curve on 1810 MHZ with 0.9V the clock became stable and max consumption was reduced to 190 Watts in Heaven. And I lost like 30 points in performance (like 3550 => 3520). So the gain is huge.

Here I set up the curve much lower than the standard boost, in order to limit more the consumption as 250W is too much for the case.

Ok understand. I will make some test.
But what I'm wondering is why we can't play directly on the voltage like for CPU. He we have a curves that goes like to the limit for voltage.
I will check if it keeps the minimum voltage only.


1/ Standard configuration
Furmark 9570 points
Max GPU power is 199W - Average 138W
Average voltage 0.91V

2/ MSI afterburner with clock at 1700Mhz (below standard curves)

Average voltage 0.86V
Average freq 1074Mhz

3/ MSI afterburner clock at 1600Mhz
Furmark 8840 points
GPU - 14°C compare to standard
Max power 155W

4/ At 1200Mhz
Furmark 7250 points
Max GPU 91W - Max voltage 0.69C

Still to go deeper into this test

Ok same behaviour. But that's nice to see how you win some watts and degrees by keeping performance.
I just don't understand as when I'm doing myself why at stock the clock is not higher than when we down clock.

As I recall correctly nvidia's boost take into consideration thermal and power limits. Default curve for the same frequency go well beyond official tdp of 180W.

As you probably know, there is a silicon lottery. 2 same GPU can perform very differently. So in order to make all GPU work out of the box the manufacturer sets the standard curve like for lower performer GPU. Otherwise, some worse GPU will crush with a standard curve.
So depending on your luck, there are big chances that you GC can perform better if you tweak the curve (lowering voltage creates bigger temp headroom).

So our goal here is to find the real needed voltage for a given clock (most times it is lower than standard curve sets). For your tests, don't lower the clock, but find the lowest possible voltage that your GC can be stable maintaining 1774MHZ for example. In this way, you will not lose any performance, but will gain in consumption and thermals.
If you are lucky like Nordl1ng you can even overclock the GPU and lower the voltage in same time =)

Hi! I purchased the second-hand monsterlabo unit, and nicolas asked me to share my experience building it. Before I get into that, I'd like to say that their packaging was extremely sturdy and personal, and no major flaws with the second-hand unit.

These are my specs:

Gigabyte Z390i
Intel I7-9700k
32GB ram
EVGA GTX 980 ftw acx 2.0 (reused from my previous build)
Corsair SF450 + additional atx cable
140mm fan (random one on clearance at my local store, NOT from noctua)

It was quite difficult to build starting from scratch - the videos were very informative but it was lacking some gotchas (like changing the back panel to the 3D printed one before starting the build). And initially, I was getting high thermal throttling because the gpu and cpu block weren't aligned correctly (the only "minor" flaw). However, nicholas and elisa were very helpful and responsive to my issues, and we were eventually able to get it working!

I do not receive any throttling at stock speeds, with my gpu and cpu hovering around 60-65 C under load. Unfortunately, it doesn't seem to perform well under some minor gpu overclocks, probably due to the VRMs overheating, so I'll need to purchase the vrm heatsink once it's available. (I have not tried cpu overclocking but it does full turbo just fine.)

Attaching an image of my setup! At this link... https://photos.app.goo.gl/U6HvkfDmxvnk43qv7

Thank you, this is a well thought out case design!

Hi, thank you for shearing.
Did you tried to stress test your CPU? I also have 9700k, but it is overheating under prime95 for exemple. I had to limit the TDP in order to keep the temps in check.

By the way, thanks to Nicholas et Elisa! They helped me a lot also!

Yes, I did stress test the cpu! For small FFT prime95, the CPU does throttle. It does not in the balanced stress test. If you pay attention to the wattage usages though, it begins to throttle >200W which is way beyond the specifications of the case. Small FFTs are a weird test since it uses the AVX2/AVX512 extensions heavily. It's not a typical use case unless you're during scientific computing imo, so I'm not worried about that.

If it throttles in the balanced test, then you might have had the same problems as me though...
