DEFINITELY Undervolt the RTX 4090.
HTML-код
- Опубликовано: 21 авг 2024
- The RTX 4090 can throw some curve balls when it comes to undervolting, however overall, especially for gaming, it will bring big gains in power efficiency. Today we take a look at a variety of scenarios from Furmark, to requiem to horizon zero dawn, and discuss the results in deb8uers video and optimum tech's video.

#Undervolt #Overclock #RTX4090
Also in the overlay the RTX 4090 Vulcan OC refers to the model name of the card, it was tested in the reference bios (no OC) for today's video (except the test at the start!). Enjoy!
You did not know the can of worms you opened.
Can't wait for you to drop the time bomb of all era so far.
4090 is the only strong card 3080 vs 4080 i think 12% in raz pref 4000 for me is a big fail
amd or intel must have something in the gun thats scaring nvidia to do this. they normally havent been this crazy with power targets up until the raytracing generations... aside from the fermi days... a generation where amd pulled ahead very much... makes you think/hope
@@hellbringer09 i dont think so… what jensen did is a gpu for mining he dont care about the gamers but the minners are gone and now its only gamers
Undervolt in summer = cooler room; overclock in winter = 4090 works as a great space heater
This is the way
@@Tofuey yes but no. In my are electricity is 30% more expensive than gas. So it makes more sense to use gas heating for me. That said I like your idea.
well said !
I don't enjoy gaming on my gas heater as much as on my 4090 tho ;) @@pistopit7142

Optimum Tech: Definitely DON'T Undervolt
Tech YES City: DEFINITELY Undervolt
Wut
EDIT: both videos have good points. Undervolting might not have quite the same performance benefits of the past. But you can get dramatically better efficiency if you do undervolt it.
they are youtubers so not smart to take advice from them al the time
Optimum wants to undervolt to extract more performance. You can't do that on this GPU it seems. It still works fine for cutting down power consumption though, but at that point you're better off just setting a power limit. According to derbauer power limits are the way to go this generation.
I guess don't do nothing then.
@@rdmz135 Yeah like PBO limiting the 7000 series ryzen... also seems like doing small mods on this generation is good too
@@rdmz135 More or the same performance. But it wont do that even when its running at the same clockspeeds you get less performance when undervolting unlike the 30 series which hold the same performance when undervolting. Still seems to work to sacrifice power usage if youre also fine with sacrificing some performance for it though but its no longer free atleast according to Optimum Tech.
Actually losing 1-2% with huge power saving is worth... i dont understand what optimum tech think... you cant see the difference between 200 fps 196fps when playing games, but you can save 70W which is really huge saving
Don't forget the RT and Tensor cores are part of the GPU power limits. In games not using these, it's easy to drop power target and NOT see a difference because the RT cores are not active.
Exactly right. Throw on raytracing in portal and watch the wattage go way up. This type of tune is only good if you are never going to use raytracing. You need a good RT bench mark and then see what results you can get with a undervolt.
Interesting comment. Thanks!
I did undervolting and game with RT on and no problems.

Both of them are undervolting wrong tho
@n n how is he an elitist for liking ITX setups? do you even know what that word means?
I've been undervolting my cards for ages now, I just ordered a 4090 and will be undervolting as well. If I lose 2-5% fps to get 20% more power efficiency (dropping from 450W to something like 400 ou 380W) it's totally worth it in my opinion, gpu is going to run cooler and quieter (although it's already a cold gpu in stock setting).
Maybe u can skip doing this in winter. ;) helps warm the room and at the same time getting those sweet fps.
Maybe his power isn't directly coming from Putin and it's expensive?
@@yyorophff786 Sometimes I would overclock just for winter and then switch it back to stock when winter was over. xD
@@salikali2 smart.
Yeah you prolly need an 4090 to get 500 fps at 1440p in over watch...... realy worth it..
Oh and 250 FPS at 4k....i bought mine (water cooled) to play minecraft RTX :)
I used curve editer automatic OC, then applied a 80% power target and i get the exact same performance to stock with 55watt saving. At 90% i get a 2.3% performance boost with a 12 watt saving. Vs traditional overclocking with +210 / 1510mhz got me a 9.2% performance boost at a cost of 83 Watts additional power!
Always tune your GPU! You can get better perfomance than stock consuming less watts!
Hey, loving these undervolting videos. I have a suggestion: make all the graphs start at 0 please. So that that the difference in height of the lines is proportional to the actual change. Thank you.
thanks! for discussing the results in deb8uers video and optimum tech's video. I was really intrigues by their claims
The problem with power limit ‘undervolting’ is that when a game or benchmark doesn’t fully utilise the gpu, there is no power saving compared to stock. Say, a game requires 65% gpu load. When using the powerlimit, the gpu will be running as stock. So, about 1050 mV at 2800 mHz. When using the voltage/frequency curve undervolt which has the same maximum performance as the 80+ powerlimit, it will run at about 950 mV and 2700 mHz. 80 watts less, with the same performance. This is what my testing concludes. So, using power limit is suboptimal, even when using +120 mHz core clock.
This
I enjoy undervolting. On my 3080, I undervolt and instead of consuming 300-350 watts by default. Which generates XXX amount of heat, which means the fans spin more, which creates more noise.
I undervolt, I get about 95% of the same performance, which is negligible to what I can see really. But only run 200-250 watts. Generating way less heat, which makes it a way quieter computer.
I know stock it would be around 1950mhz, undervolted I could run it pretty constant at 1900mhz.
You actually lose performance by undervolting? I thought it would just crash
I already undervolt 150-170W GPU's, so you can definitely expect me to undervolt this heavily when I get mine.
I have undervolted the i7-4510U, the 1500X, the GTX 1070, and the 7600X.
You bet your ass I will undervolt my next upgrade CPU + GPU when they come out.
@@ShadowbannedAccount Very nice. As a follow up to my original comment I will say that my undervolted 4090 is drawing between 200-250W at full load depending on the game. That's a decent drop from the stock 400W so I'm very happy.
@@Krenisphia Mind sharing some more information? Like undervolted how low, how much you OCed the memory, and how your performance is compared to stock?
@@dadsaysimcool Of course. I played around with different voltages and eventually found the sweet spot for my particular card to be 2400Mhz @ 0.825V. Performance loss is only around 5-10%, considering the massive power savings that's very good. I also OC'd the VRAM +1000Mhz to get some performance back.
So where is guide how to undervolt and adjust vram? :)
I see the curve is -161 but what Mhz did you drag 950mv to? I was unstable 950mv at 2800mhz but I used -240. I'll have to try -161. It was stable at 975mv but I increased to 1000 to be safe. Stock is 1.1v. Edit: Playing a bit more I'm getting a 0.8% loss at 385W. Less than 1% drop in performance for a 65W drop in power usage.
That was a bit confusing for me too, so the stock was 1.111v (1111mV), and the whole curve was pulled down -161mV, ending up at 950mV.... I'm understanding this correctly... uhh, right?
For a brief moment, seeing R9 7950X on screen made me ask "wait, what year it is? why did we get back to a 10 year old gpu"
Same when seeing Intel discrete graphics cards; "Wait, is it 1998 again?"
In South Africa we are subject to scheduled power cuts that last for 2-23h at a time. I am going to try and get close to the absolute minimum power to performance on a 712Wh budget , CPU is in ECO mode and then a sensible undervolt when we do have electricity.
I would never have thought to boost the vram clock when undervolting. This is great!
Indeed the VRAM overclock is the performance equalizer, what you lost by lowering core power can be some what be giant back by maximized VRAM speed.
Yeah, the point of undervolting has always been better performance per watt, reduced temp is just the bonus. It's just that the sweet spot shifts depending on the silicon quality and your performance goal.
As long as temps are in check, undervolting the gpu for an increase in its lifespan (at least in a reasonable period of years) , i doubt it, less power draw, for sure.
Good video Brian, 👍
I have ran my 970 for 7 years (now on my work pc) and it's had heavy use. 5 of those years was with a heavy overclock and it still works a charm. Saying this, every AMD card I owned before has dies within a few or so years. Thinking of the HD series.
Thanks for this video. I recently picked up a Windforce 4090 and immediately power limited it to 60% (using GPU tweak III like Derbauer suggested). It still obliterates anything I throw at it in 4K ultra and I've not seen the power usage rise above 350w. Edit: also, the fans never spin up to max and temps sit at around 55-60°C even after prolonged use. This performance uplift is like a whole new Sandy Bridge moment. Excellent tips, cheers! 👍
Thank you, keep up the good work! I used MSI Afterburner's Voltage Frequency curve editor to lower voltage and power consumption on my RTX 3080 Ti. Have done it on previous video cards as well, including an RTX 3090.
WTF the 4090 can easily be a 350w tdp card if Nvidia didn't purse the extra 5% or so extra performances and they can even save on BOM cost by reusing 3090 FE coolers and heatsinks
I love how we have 3 Desktop GPU brands now and the competition is good.
And now we have Tech tubers having competition how to undervolt, we like this guys keep going!
Do you have data on 1% and .1% lows and how undervolting impacts that?
Do you have a Samsung Odyssey Neo G8 you can test with the 4090 at 4k 240hz with hdr turned on in windows 11? Thanks
I don’t know why people are confused about this video compared to Optimum Tech’s. He says to not under volt as a form of overclocking, which makes sense when the last GPUs got more performance from undervolts. This video says to undervolt to get similar performance for less power, not overclocking, which makes perfect sense.
It's the best thing for many years, always preferred underpower to undervolt. The best thing to do is core oc + memory oc + temp limit (usually 65 degrees or lower, so as to have hot spots and memories at 75 degrees maximum in gaming and under stress, not mining. In short, adjust the temperature so as to have memories and hotspots at no more than 75 degrees).
So the PL is based on temperature but you have to remember to choose to prefer the temp limit to the PL in MSI afterburner.
The thing is that GDDR6X is already 80C on stock speeds on the RTX 4090. I have seen copper shin mods drop temps by 20C on the RTX 3090s. So this will be the case again I guess for RTX 4090 for max VRAM speeds.
@@N0N0111 Put 60 degree on max core clock and memory drop to 70
You should do a video just showing how to do the undervolting.
For me its not really clear how to do it.
i wonder if we'll ever see underclocked cards from one of these companies..a lot of people prefer lower temps/low wattage. they don't even have to lower or higher the price..could simply be a marketing strategy that actually does something positive.
Imagine buying a £1800 GPU and worrying about 3p electricity an hour 😂😂😂😂
Higher clock speed and slightly lower FPS sounds like the GPU correcting for instability. Sometimes in Overclocking, you’ll speed something up and get lower or equal performance and that’s an indicator of instability. There are some methods of error correction in BIOS and I don’t know what they are or how they work but they do result in lower than expected performance. Ex: if you add 200mhz to a CPU and it doesn’t crash but your cinebench score is 300 points lower than before, chances are you would be able to detect instability in a prolonged torture test
Have an RTX 3080ti EVGA, undervolted it to 220w max. My PC draws 300W with the CPU/GPU. The RTX 4090 alone draws more power than my PC. LOL
How to undervolt inflation?
Wow, the gains are impressive!, almost 100watts...
What about doing the auto curve oc and just reducing the power target 10 or 15 percent?
Just bought a 4080 for my latest PC build, which I’m about to embark on and this video is greatly appreciated for how I optimise my system. Many thanks:)
Very useful information. Any advice on undervolting a rtx 3080 gigabyte oc? Running on the recommended 750w psu but would like to take the wattage down a notch just in case. The temps on stock settings hover around 65c so thats not a problem. Would ofcourse get less agressive fans when it gets down in temps more.
run it on 1900mhz with a vcore of 0.85. i do that and it sucks up to 270 watts. if it crashes take vcore up to 0.875. that should work perfectly fine.
@@Embreh89 Thanks man. That seems to work. In cp2077 getting 275watts instead of 320watts i saw before. Unigine heaven for some reason pushes it still over 330watts but i dont see it in any games. Stock it was running max 1875mhz before when it pulled 320w. Temps have reduced 2c and the fans seem to run quieter.
@@alvar891 now fine tuning is up to you and depends on the card itself. ive seen cards that can do 0.8 vcore on 1900mhz
@@Embreh89 need to find a way to push it to crash. Heaven and cp2077 do feel heavy stressing it but no crashes yet.
my 3070 aorus master was the first card i ever explored undervolting on and it pretty much saved the temps hotspot would easily reach 90c+ and core would be in the low to mid 80s after the undervolt gpu sits in the low 60cs hotspot is low 70cs usually about 10-11c higher than core ezpz gpu is at 2025mhz @956mv mem +1020 card pulls 200w max it was 350w+ before didnt lose much performance either definitely worth doing especially these days! :)
rtx 3070 pulling 350w? did u mean 3080?
You're the undervolt master.
I'm the crashing master
I'm the broke one
Tech YES vs Optimum UNDERCLOCKING BATTLE!
Okay so I Undervolt always. This is a biased topic but generally widely accepted. Pls explain the performance differences (at 4k mainly) when running at 8x vs 16x while undervolting. I got a gen 5 ssd that shares lanes. But I was curious to see if I change to x16 and just run the ssd in gen 4, and undervolting, if my 4090 will run even better. Or should I just undervolt and keep it at 8x ?
Looking like my evga 750 watt PSU is still good to go. Cheers Brian.
With G-Sync, Free-Sync and even classical V-Sync. If you have a grfx card that's faster than your monitor. Enabling it significantly reduces power consumption. Since the card isn't rendering frames and it csnd display.
On my RX6900XT. It certainly reduces the heat output.
Here I am learning to undervolt a 4090 when all I have is a gt710
Man 1 question please, what is the maximum voltage of Ada (a.k.a. RTX 4000-series) IF you put/set the voltage slide in MSI Afterburner to +100%. It's 1.000V, 1.050V, 1.100V or more? Thank you. For example I remember if I'm not mistaken that in GTX 1000-series the maximum voltage is 1.093V so I wanna know that (the maximum voltage) in RTX 4000-series and RTX 3000-series if possible, thank you.
1.1v is max voltage for every nvidia gpu since pascal, competitive OC gpus sometimes push it further but nvidia is very strict with changes to any voltage across the card.
This is good news for the 4080 12G since it should be really a 200-220W card that can inch out some playable 4k or ultra smooth 1440p with the curve optimizer while running relatively quiet on air cooling.
They cancelled the "4080 12GB"
I think the Performance Difference is because of EFFECTIVE Clock.I have noticed this with 1660ti,1080ti Rtx3070/3080.
I use Msi Kombustor to check the Difference between Clock and effective Clock and make different Profiles in Afterburner
The Asus 3070EKWB i currently use has only 250w PL but with my Curves i can beat Cards with 300w+ because the Chip only needs 0.950v for 2000mhz instead of running into Powerlimit at 1.075v default...Insane Powerlimits are only good for Benching,for 24/7 you go with the Sweetspot.
btw there is a Zotac 4090 Trinity with "only" 450w PL waiting for me at a local Shop,Time for some Curve Magic ;)
Just when everyone got to an agreement that you can't undervolt it properly and it's better to just set the power limit ... this video happens 😅
Save power! Save Money! The Tech YES Way!
Corsair platform 860 watt i7 9700k 32gb ddr4 you guys have heard the story it was only 200 more for a 4090 so I got it and now everyone online is uh worrying me quite a bit lol. Should I just turn the 4090 down and put the 9700k back to stock until I can replace the psu? I have 2 hdd 2 ssd and 6 fans no rgb no opticals 760 load wattage 810 watts on the exact calculation. Cpu at 1.2v and i put extra oh the calculations to be sure.
Setting the 70% power limit is easy, I don't really understand what you're doing or how you're doing it with the curve optimizer. Maybe it wasn't in the scope of this video. Could you explain in more detail what you actually did to get better results?
trying to figure out as well what his final settings are, and if the curve optimizer bar graph is including the 70% power limit or what? i hope someone can explain. noob here
@@juan-in3cw Using the curve editor I was able to set 950 mV to 2805 and 960 to 2850. When hitting apply it seemed to help flatten everything after 960 mV to the same value. I also added 1000 to the memory clock. Using unigine Heaven as a benchmark I saw modest improvement over stock. What was interesting was that at stock it didn't go north of 80% power often anyway. With stock at 70% power limit, sometimes it briefly went above the power limit. But after using the curve editor, regardless of power limit the card never hits 70% on this benchmark. So it's running at a consistent 2850 Mhz with 11501 Mhz memory with power usage in the %60s, temp is averaging around 60 c as well. Still don't know what I'm doing though, basically just copying him.
using curve editor gives you the advantage that you can accurately optimize voltage and frequency
Just reduce the power target and don't touch anything else let the GPU do the job.
excellent video on explanation, one of the best currently on youtube, can you please also discuss the bottleneck affect of display port 1.4 on the 4090 ? Does getting a high refresh 4k monitor in the future actually do anything when 4090 is hard locked to 4k 120Hz due to DP 1.4 ? No one has done a topic on this yet and I think it's a critical one that questions the future proofing ability of 4090
It’s really not a big deal, 4K 240 monitors with Display Stream Compression on DP 1.4 exist right now, so the 4090 isn’t really “locked” to 4K 120. You can test this yourself if you want to buy a 4090 and Odyssey Neo G8.
@@joemarais7683 ah ok, ya, I don't have an extra kidney to test it myself so I'll just take your word for it
using 0.915 @ 2700mhz, i tried to use 70% pw at the same time.
but.... but... but... Optimum Tech told me not to? ;.;
what do i need to dooo?😂
dont believe youtubers to much xd
Pick whichever youtuber u believe more and seems to help with performance more... i personally would just try undervolted vs non undervolted for the games u play tho.. :)
Theres this crazy idea going on right now, its where you actually try them both. mind blowing right?
I only just started playing with a RTX 4090 today and I was pretty much seeing the same thing only briefly playing with the power slider in RDR2 and Cyberpunk. Even when I start by sliding my core clock as high as can without crashing and then start sliding the power limit back I can go down to 70% with seemingly no change in games I do notice the core frequency not remaining quite as steady resulting in slightly lower score in 3D Mark but it seems like something you are more likely to see in synthetics than normal gaming.
Thanks so much for your thoughts on this topic, super helpful. I noticed for your tests, that you are using a 850w power supply (which I know is what Nvidia recommends for a base line). I was curious what your thoughts are on people that are wanting a 4090 and needed power supply?
I have seen such a wide range of advice on this from 850w being enough to needing a bare minimum of 1250w power supply. I have a 1000w power supply and at the time I was purchasing it I wasn't considering a 4090, now I am. I would get a 4080, but knowing the dollar to value is so poor compared to the 4090, I want to just go for the 4090(assuming I can get it). But I fear I wont have enough power with 1000w(And a 7950x cpu) to run it without problems. Your videos give me hope, with just the base line for what power draw looks like out of the wall, our systems are not that different. I plan to seriously look into the undervolting you talk about in this video, assuming I can with a Asus motherboard. My machine is more for productivity (Motion design and hopefully 3D), gaming is secondary. Besides most of the games I enjoy playing these days are nothing new, so performance would almost be no different for me.
Thanks again for doing these videos.
I am on 750w supply, runs fine even with no undervolt and 5800x3d (100w). Undervolt and curve optimized both to silence.
@@unotoli Thanks for the response and your experience. a few of the calculators, online say I will have enough overhead for my setup as well.
Nvidia pricing is outrageous, but this card is a mega bomb. Too bad they chose to not include DP 2.0. This card would have lasted you for 4/6 years.
The 240Hz 4k screen that exists uses DP 1.4 with DSC. No DP2 screen yet exists, and DP2 only gets to 144Hz uncompressed at 4k.
A lot of people have a 120Hz screen and they, like me, will be happy with that for years to come.
@@Safetytrousers wrong, dp 2.0 has the bandwidth for 4k 240hz with no compression, not 144hz. No display exists yet but they may come in the next 2-4 years and 240hz is quite nicer than 120 while playing fps games. So it’s not great to not have it.
always believe in tech yes city! king of undervolting
Hmmm interesting , saw OptimumTechs video about undervolting the 4090 although he had the founders edition card his results were worse in every game he tested.
I think he did not oc the vram, and that is the point really to get the 95% performance number and not awful 0.1% FPS down spikes.
So if we reduce video card consumption, we make it safe for the cable? Is the risk of melting the cable reduced?
yes
Even if loosing 5% fps, the dps this thing outputs anyway you wouldn't even notice..
He mentions a few times to make sure to tune memory, how exactly do we do this?
Sorry new to undervolting. So overall recommendation was to:
- use curve optimiser
- set power to 70%
- tune memory?
Add +100 memory clock, run a scored benchmark, see it finish and note the score, then repeat until you see artifacts, the benchmark is unstable or the score begins to decrease. Then fine tune the exact peak score with repeats at +/- 25 mem clock.
And you should do this last, and separately from testing stability with power targets and voltages/core clocks.
But what about all the benchmark queens and all the framerate princesses?
Hi Tech Yes City.
I'm looking at a Galax RTX 4090 SG, are they any good?
Hey yo bit late to the party but my MSI 4090 Gaming Trio X hasn't yet been over 48 degrees even on full load - this is in a 20 degree room as well. Still worth undervolting? Where's the voltage optimiser in MSI Afterburner? Thanks
This is so correct: Undervolting is not only limiting the core to a voltage for a MHz speed, but also testing for max VRAM speeds.
When you don't mention VRAM speeds than your undervolting guide is faulty.
undervolt ram make them run slower?
Undervolting is something nearly all of us should be doing. Any added efficiency is worthwhile, especially these significant amounts.
Interesting, I have had my 3060 at 950mv and ram at 8300 with better than stock results in FPS and power. I'm been surprised more haven't been on board with this method. And no one seems to talk about the limit that occurs and is shown in HWinfo at stock settings. Or the potential deficiency in the pci voltage regulator on the cards (opinion) via monitoring pci power vs voltage drop as measured/reported by the card (voltage drop more than desired, still within 5% spec but...).
With this said, we have great products that do the job and we seem to be getting there.
Stay cool ; )
Idk did Ali crank the mem clocks in his tests? Could be the clear reason for different results
I'll be undervolting myself in a couple weeks when my card arrives.
@Brendan nice to hear. My FE still hasn't shipped but I'll be stuffing it into a Dancase H2O so it'll be tuned down right out of the box
@8:20 there's GPU core clock and effective clock. The effective clock is why fps is not as high even though the core clock seems unchanged.
I'm having an issue with undervolting on Afterburner? It doesn't seem to save my undervolt, but instead bounces between the stock 1.05v and the undervolt I set it to. I checked the boxes for 'Unlock voltage control, monitoring, and force constant voltage.
Limit the power to 70% from msi afterburner and end the day. When you need more power just move the power slider, no headeche. Or what gamer nexus found just plug 3 instead of 4 8pin 😂
I'm undervolting and power limiting my 4090 for the sole reason that I do not want to melt the 12VHPWR connector. As a bonus, things run cooler and quieter as well.
As a bare minimum, power limitation is a must. But I find that I gain a couple of fps by also adjusting the voltage curve.
Ok we need Steve to do a video on this because THIS is wrong. OT is right in a way in that, with this much money spent why even under volt? Just leave it at stock and don’t over clock(not that there’s a reason anyway this thing is crazy fast without it) if you want it to live(hopefully) a full life
I dont seem to have voltage control on mine, but it rarely goes over 300w at 100% so it seems to be pretty good by default, its usingless than the 3070ti FE I had for a short time.
I can overclock a bit and keep it at stock 1.050v and run it at 3ghz, havent done to much with the Vram but I think the limit is around 500 but im not sure about that. ( overclocked the worst powerdraw ive seen was like about 450W)
DEFINITELY Undervolt your mouse, keyboard, mousepad and your dog. What the hell... Undervolt everything
I did it There is no real advantage decrease a little' watts but in some heavy games you see the difference in FPS at the end do an Overclock avoiding that the gpu goes to 1050 or 1100mv
But the temperatures are already low as standard in my opinion it does not make much sense especially on the 40/90 which is already a monster of Power.
Indeed I could say that in some games at 4k you lose a lot of FPS the fact of running the gpu at a lower voltage
I have always undervolt all cards. These 4090s don't overclocks well at all anyway
Thats because we are voltage limited this time. We need more voltage to OC lol
Interesting video 👍
All this video showed me was there isn't one setting that's better than stock.
Optimums point was undervolting shouldn't result in lower FPS. I agree.
Nice video mate
Any chance for a W11 22H2 optimization guide in the future? 🤔
Wait until you combine overclocking and capping the power. Let the driver handle the gpu frequency dynamically, just overclock the cpu by 100-150Mhz, and memory by 1250-1500Mhz.
I don't understand what he's doing at 6:54, is he substracting 131 mV from the voltage of 1.240mV and is he increasing the voltage cap by +259 at the 0.950mV margin?
80% power limit +1000 memory +150 gpu
Not a fair comparison against power targets when you also OC your mem to boost the curve optimizer numbers...
So... I plan to get a series 4k. What's better, a UV 4090 or a 4080?
Slight increase in FPS and TimeSpy Extreme score for ~50W less watts and 4 degrees cooler. PNY 4090 (by far the smallest of the bunch) 137mm height, still rocking my decade old case.
i would've liked to see a 700mV undervolt, just to push the power as far down as possible, and how much FPS you lose by doing that.
Hey Bryan, maybe you can do an Indepth video on Nvidia undervolting I got may clocks locked in at 900 mv @ 1920-1935 MHz, on the + 800 memory slider on by RTX 2080 super but sometimes the clock will jump up 1965 Mhz while gaming and the game crashes any pointers on how to keep it locked in?
I've read elsewhere than the uv wasn't that efficient on the 4090 and it was better to lower the Power limit?
Thanks heaps mate.
I usually OC the memory to the limit of stability and undervolt the core. This recipe just makes sense to me and has worked well for me.
Also helps crappy GPUs not constantly thermal throttle and eventually burn up their VRM and Memory.
To what university told you that that about golden samples? If the silicone is better that only matters for the highest pick frequency that is not achievable at any voltage. All 4090 will get the same results at @950mv and they will differ at 1.1v. Get the facts.
6:58 why is it -131 on the curve graph but -161 on his bar chart? sorry noob here, please explain
is it really needed? don't we need more to watercooled it?
Wtf, who cares about efficiency on the 4090.....
I don't get if you underpower AND undervolt the card OR just undervolt it.
How is the requem,Brian?
