The Elmor EVC also works for a huge amount of other cards. If you ever want to try something like this you can get it here:
elmorlabs.com/product/elmorlabs-evc2se/
(this is not paid, but I love Elmors work!)
It is so weird that you just hit 100K subscribers. Man with a bigger knowledge than other youtubers. I wish you all the best and hope your channel will quickly grow to millions. I like your videos , great job!
thanks for featuring this @der8auer... but does the elmor EVC work for the 4090 founders edition? because maybe it uses different VRM controller (the new 16 phase one). compared to these other AIB cards?
another question... does the asus TUF share the same PCB as the STRIX? (and with same voltage VRM controller?). Since I can afford the TUF here but not the STRIX, is too expensive. Of course you cannot know this without having both cards to compare.
They've intentionally designed these cards so you cant undervolt them(thats the take i get with the less preformance doing it) and thus have them last
thats evil
and another reason to pass
which one do you recommend more? Aorus master or Strix?? I am planning to build with one of those two and can't really decide
you are on a completely different level than other tech youtubers.
You have know Teclab channel, they are the best moders.
Because the market for delidding CPUS and soldering 2000€ GPUS is like 0.00001% of the population
@@DuBstep115 but that's the fun part :D
@@der8auer-en just now realised you do these videos in both english and germany, not just dub it. Hats of to you, insane dedication
@@DuBstep115 actually cuz most of them are just reading the spec sheet and running some benchmarks, and creating bs thumbnails, anyone can do that, but it takes experience and electronics knowledge to thoroughly review something like is the VRM design good, power delivery, components used etc even though der8auer dosent get everything right myself being an electronics enthusiast i just really appreciate that the content at least goes into the hardware
As someone who cringes at new GPU prices, I would never attempt this on my own.
But seeing you do it is like watching someone drifting in a Ferrari, it's ludicrously enjoyable.
This is just on the whole new absurdity level of power consumption
It’s impressive that manufacturers are dialing in their chips so well. The golden days of crazy headroom seem to be in our rear view mirror.
Undervolting did make the GPU a bit slower, but 17% more efficient
I almost always undervolt my cards a little bit, the last small % of performance are rarely worth the extra power unless you really need them for something special.
@@kevinmalk
How far did you go?
My RX470 went bollocks if I lowered the voltage beyond -30mV. I've heard people go as low as -100mV. Is that true?
Dont think 90 series buyers want efficiency
@@cor74 sure, they was inefficient from the moment they bought it 😂
That GPU is just a huge overkill.
@@Talkshowhost23 nothing is overkill if you're rich enough
Damn!!! Why board so short? Feel sorry for the textolite on a video card for 1600+ Euros? And it's Asus Strix! I can't believe my eyes, why is this happening and what is the reason?
As always another Great Drill Down. You always get to the point. I think you need a couple million Subs. Unfortunately there arent enough geeks. Thanks for all you do. Thanks!
Thanks a lot! Will invest in more snacks for Shiek and Makita :D

Great stuff. I love when you push the limits of hardware!
That's what she said
LOL. Limits.
This is why I love der8auer.
Was looking forward to you doing a voltage mod since you put out your last video! Excited to see how far you can push this card with a power mod 😀
This is the type of content no one else is doing. Interesting. I like it! 👍
that is because the rest of channels and overclockers are still investigating on how to break world records, roman is just first, you kow that gamers nexus eventually will do it on ln2, probably jayz2cents too between others
@@arch1107 they don’t do voltage mods like this. They might use LN2 but they openly admit they don’t know the pcb parts like Roman.
@@mikezappulla4092 iirc they do some basic stuff, but yes, a engineer and overclocker like roman is the only one with the time, money and knoledge, follower by few other youtubers, like the guy on actually hardware overclocking, i think he matches in knowledge roman
steve knows alot of things but interpret pcb designs is not yet on his reach
I can't wait to see you power mod the card!!! You're freaking awesome dude!!! It's so fun to watch you work, & figure things out!
Its always a joy to see you do modifications, you're so dedicated.............thats what I like about a person doing what he likes with the utmost dedication.
Couple of protips for soldering annoying ground pins:
1. a higher power soldering iron (higher thermal power in watts, not hotter in degrees) will do the job better because it can apply more thermal power to the joint than the large plane can conduct away, thus overcoming the thermal conductivity and causing a higher local temperature increase for a smaller non-local temperature increase. same principle as TDP of a CPU vs. TDP max of a heatsink. the flipside of this is that the iron's temperature control feedback loop needs to be higher quality as to not cause overshoot. thermal overshoot causes your iron temperature to temporarily exceed the target temperature, and an iron that's too hot will burn off the flux and potentially cause pad delamination.
2. preheating the board with a little hot air as a "thermal soak" reduces the problem because the delta between the board temperature and the iron temperature is decreased. you're essentially saturating some of the thermal capacity of the plane so that it can't "absorb" as much heat from your iron (simplifying a bit here), which again results in higher local temperature increases vs. non-local temperature increases during soldering. this is my preferred method because you can use a decent general-purpose iron (e.g. FX888D) and a decent general-purpose hot air gun, rather than needing to buy a costly high-power iron with good temperature control. run the hot air at 150C or so, high flow, and warm up the board area in a circular motion, starting wide and far then moving inward and closer. it shouldn't melt plastic or lift any SMDs. only takes about 20 seconds of preheat to make these joints a ton easier.
I'm guessing you know most/all of this, but folks in the comments might not and I often see people trying to compensate by turning the iron temperature up! (super risky!)
awesome video brother as always you definitely take it to another level. love the fact you open something up and see what it's about. looking forward to seeing your next video
Other tech tubers can't tell if a cable has solid cores or stranded cores.
We are lucky to have der8auer and give us real world scientific experiments.
Congrats on 100k on the English channel, btw! Loving this "for science" content. It's great :D
This is just crazy, cant wait for the next video! :D
Looking more and more like nVidia have tuned these cards right up to the max. Great job on the video!
They didnt leave much room for improvement for their AIBs. Higher prices and very small improvement and smallish profit for the AIB. Nvidia going the way of Apple now.
It's more sinister than that
@@smugmode I don't know about sinister but it smacks of a weird mix of arrogance, panic and paranoia. Calling their new "feature" DLSS 3 is even misleading, since it's DLSS 2 with a separate additional "40 series only" insertion of faked frames. Looks great for benchmarks and makes comparisons difficult, of course.
@@halrichard1969 Tim Cook deserves the right hook
@@cherry_blast2984 Never thought much of Tim Cook. Not an innovator just a care taker.
I have worked in I.T for nearly 19 years full time and I still don't quite understand everything you talk of. I rewind, pause, Google, etc and I am really thankful and impressed. Thank you
Thank tou Roman for taking time to do actual testing on these devices.
Also it's a convention red/black is always supply, you can take ground anywhere on the card.
really impressive! great job! well done!
Glad you touched on the undervolting question.
The lower voltage same clock also happened when undervolting the 30 series. You basically end up clock stretching where it's not fully stable but it's stable enough not to crash
Probably why my gpu doesn't crash but flashes random rainbow blobs sometimes
Just love the soldering on a 1v old flagship gpu ❤️😁 power to the cutting edge tec tubers!
When will we get voltage hack?
LFG! Always bringing the good content!
Nicely done, and now I get why they locked the voltage.
I've been waiting for this!
Would also really appreciate a review looking at the amount of reduced power draw under constant loads while lowering temperatures, TSMC’s 5 and 4 nm processes seem to like that quite a bit.
The cooler is amazing! What a fantastic heater for the winter lol.
I love that the subtitles have "Founder's Edition" as "Furnace Edition"
Thanks for you efforts!
Thanks der8auer, you are absolutely awesome. I really enjoy how you ask questions about hardware and then test your hypothesis in the same video! Others simply ask the questions and shrug, never to find the answers themselves. You have a true engineers mindset, THANK YOU!
I'm just curious, now that we've removed the gaming GPU bottleneck at 4K, is it possible you could test some CPUs at 4k? I haven't seen others do this with the new 4090s. I'm wondering if we have a new value CPU king at 4K? Especially wondering if 5800X3D still stacks up well against Ryzen 7k series or how the 5900x compares! Do we have any values or must we simply pair high end GPU with high end CPU? Thanks!
This is insane 🔥🔥🔥 great work
Would undervolting the processor on the gpu help or would you just hit the wall of the boost clock speed set in the card’s bios?
Thank you for quoting weight data; this confirms my suspicion that these cards weigh more than an entire 15" laptop, lol. I'm excited to see what these cards will do on water cooling/sub-zero...
I don't care that much for overclock anymore these days (loved the days where it could easily give you insane gains). Still like to see your videos for it's very informative and you never know, there might be a chance there is performance increase to be gained.
I run my old AMD Ryzen 7 3700X 3.6 GHz at 4.2 GHZ with the box cooler. When you only have to run the Ryzen Master program, the extra performance is well worth it.
@@Varangian_af_Scaniae Yea but back in the day with some old intel CPUs you could go from like 3.2 ghz to something like 4.6ghz with just simple OC and all you needed was some typical air cooler. Back then overclocking was very worth it and made the cheaper CPUs great deal.
seriously. overclocking the crap out of my 6800xt, air cooled, gains so little for such a huge cost. honestly i dont know if thats a good or bad thing. probably good since the assumption is that out of the box you are getting the most out of your card without doing extreme overclocking with super cooling which in my case is overkill unless im doing it for the fun of it but not practical at all.
@@megapet777 is it worth overclocking the cpu though? personally i dont see any difference in gaming. i have the 3700x as well.
@@godw1ll99 i have 5600x and its like 2-5 fps increase. Really no point, same with GPU rather just leave it
Thank you for your videos!
I want to see that power limit mod. Sounds next level
Good work Sir, I can see you smiling :)
amazing mod, roman. thanks bro
Would be curious to know what kind of effects pushing the limits like this has on longevity of the gpu.
Damn man this made me miss the 8800 GT/GTS/GTX days where we used to solder on a little turn knob to adjust the voltage :) Or pencil mod on old X1950 for 1.4V :) keep up the high tech overclocking bud !!
Thanks you for doing the English version of your videos.
Really want to see some of these cards pushed to breaking point with shunt mods and water cooling!
You're a madman! Love it
a tips for that small voltmeter, add a diffuser sheet to make it easier to see under light.
This is some next level stuff my friend YES let them know what hardware is all about !
Can't wait to see the next video with the power limit gone 🍿The amount of power this card will draw is going to be insane with the limits removed
when I watch your vids I get reminded why I pursued my course
Awesome I have the evc2 will definitely be interesting to test. Curious how these cards act on ln2. Hopefully the memory doesn’t go to crap cold.
What was the actual power draw (in GPUZ) when you hit the PL? Did it get to 600w or something lower? My TUF OC seems to limit around 550w with the 600w bios.
Wireview could come with a very small extention cable from the wireview to the gpu. you could use if the gpu power connector was backwards. Maybe better than making a hole new model.
What was your 3D Mark score or some game framerates? I'm curious what a 3GHz overclock gives you in terms of performance on top of stock.
No idea what you did there, but.... interesting stuff! 😀👍
Thanks
The point of the three adjacent through-hole pads next to the voltage readouts is so you have an accurate local ground reference to measure from. Due to the high current flowing through the ground plane (primarily return currents) there will be a small voltage drop across it, so if you measure from the far side you're not necessarily getting an accurate reading. The 90mV you measured between those those pins and the grounded screw pad is exactly that - both pads are connected to ground, but the ground plane has a nonzero resistance/impedance so there's a voltage drop between the left and right sides. If you measure that ground plane drop during operation you'll find that it shifts a little as the current draw increases and decreases.
If you connect a differential oscilloscope probe across those points you'll likely see some high frequency noise caused by the dI/dt from each VRM phase switching in sequence. The voltage of that noise is the summed vector magnitude of the currents flowing through the plane multiplied by the impedance of the plane. In designs where there's a high-current section alongside a low-current section containing sensitive (often analogue) electronics, and where all the signals between those two areas are differential and isolated (e.g. with an optocoupler or galvanic isolator), they'll often split the ground and power planes for those two regions and connect the high-current and low-current ground planes with a ferrite bead to prevent the ground plane noise leaking out into sensitive circuitry.
I have no idea what you just said, but it sounded smart.
Thanks!
With the IPC/Watt efficiency of the 4090, could a moderate performance gain be achieved without making a space heater out of my pc? Or is that within the realm of the card running with G/Free-sync on and fps limited?
This is insanely helpful video for evc2 and strix users. Can you do sams for suprim if possible ?
Jeremy Clarkson, for once, seems appropriate:
"Speed, and power."
I do remember one day, when my friend bought a GTX 580, he did what i did not expect.. he got an another GTX but this time, broken 590 which is dual chip card, he just cut the mosfet board out of this card and made every connection needed for get a working 580 card, he also moded a bios and hoked some programming probes to the 8 pin chips on the board to manually increase voltage to the card. He pushed this 580 to its absolute limit, core clock was 900MHz higher than what card gives you by stock and the powerdraw was increased from 250W to 390W. The card was faster than dual 590 in some games and benchmarks and equally fast like GTX 780 back in these days. And also he removed stock HS and replaced it with water cooling..
Reminds me of the old Intel P4 days and the Abit IC7-Max doing volt mods.
Excellent! Subscribed 🙂
Can't wait for that to come💪.
very good you are very strong i hve question wich model rtx 4090 is best and faster ??
Fyi 900w is the rating for most small bathroom heaters... Yikes
winter is coming :D
How much power can the PS connector supply? It would be interesting to see the VD under load. It might be a good test to see if an automotive voltage stabiliser and battery could help when going extreme with overclocking.
But if you drop voltage then surely the performance can only decrease slightly at some point ?
Strix: *Uses all the power*
This guy: *Somehow uses more*
I wonder if I should buy 4090 or wait for the possible 4090ti. Also would be nice to see what the temps are with ek-waterblock, since I need to get one due to my old 1080ti is watercooled too, so would be too much work to not just add new card into the loop.
Buy the 4090, sell it and buy 4090 ti
Wondering where you got the Digital LED multimeter..!
so do these 3GHz overclocks match the prerelease rumours of huge power consumption? i am wondering if a 600W power target was in the mix early on in development and was later reduced by Nvidia since the performance was good enough at a lower voltage.
Looks like a mad science experiment.
That's exactly what happens when I get my 4090 rog strix oc over 3090 MHz - black screen. Sometimes an ad shows up as well.
In 1440P, if you run games at 200% render resolution (4k?) Does that life the bottle neck? Or does it have to be native 4k?
Always new sensations. A new threshold.
@der8auer-en Thanks for the video. Can I ask you if this kind of controller would also work on hardware-side undervolt mobile ryzen apus?
I'm trying to find that WireView device but coming up empty, who makes it? It looks really nice.
Master class in overclocking. Cheers for the share mate!
nice, card looks great, more powa!
Shoutout to Optimum Tech! Nice 👍🏻
This man over here about to unleash the demon
i have been searching about this topic for the last two hours and gave up , then i go to youtube to find something to sway me away from this and see der8auer uploading this
this channel for me is high end just likeGamers Nexus hardware unboxed and digital foundry Thanks for the content.
How the hell do you only have 138k subs? That’s a lot but should be much more for what you provide…
Great video.
what about clamp meter at the 12V cable to monitor it atm ?
The only one that does Overclocking on another level, everyone else is basically only relying on software only.
Cant wait to see what he will manage to achieve in future with this card.
I can't get over how freakishly huge these cards are.
We need more hardware overclocking and tweaking videos like that.
so what was the maximum board power wattage of it?
I still can't figure out why they don't put the power connector at the end of the card to keep cable flex and plug strain to a minimum
some good content right there
Every generation, you are the only dude i fully trust as far as testing the new hardware.
thank you again!
What about GN? They also have great reputation and they do pressure tests, Schlieren imaging etc.
How come the 16pin power connector didn't melt at almost 600watts?
I'm confused, shouldn't the card have dual bios with 500 and 600 watts tdp?
I see the board power TDP is 98.2% at 491, what is going on?
Awsome video. But i wonder is the Power connector going to be the limiting factor? 600 watts through not so big cables is already something. If you could get it to say 800 watts, what will happen to the rail of the PSU? If they are all equal it will be fine i guess but if there is an offset between eachother that might be a big issue!
People have been getting 1000 watts out of 2080ti and 3090s.. not sure how orc where the juice is coming from
Just Remember guys With Insane power comes Insane responsibility!
The voltage reduction loss tracks Ohm's Law. If the voltage drops, but the resistance remains the same, there's a corresponding drop in current. When one is talking about 3 billion or so operations per second, any slowdown in the ability to charge & discharge gates on the tiny FETs in the die, will tend to net a performance decrease. Gotta watch those thermals though.
