This is super helpful, thank you Bryan! Many over/under clocking tutorials assume user is already familiar with software, and your down-to-earth approach makes it much easier to grasp the basics.
This is the only one that went over basics and easy to understand- I know this is 7 months ago but it just came up in my feed- 4070 Ti went from stock .950 volts to .900 @ stock 2490 MHz with the flat curve to the right and wow what a difference. a good 80 watts less power and cooler too ( not that it was ever hot ) your GPU just seem to run better at the under volt in every way- great job !
My first attempt of OC'ing my GPU. Great tutorial for any card! Worked absolutely as shown here for my RTX 4070. I went with the under voltage option as my FPS is working plenty good for all my games I"m currently playing. Remnant2, Elden Ring, God of War, Mass Effect
Does that include 1% lows, frame times and overall stability? If so I may have to consider the 4070 for my next desktop PC. My intent is to build a desktop which has similar or better power and efficiency to my 3070 ti laptop without any of the noise. I want to prioritize power efficiency and price to performance for this build because I just want a smoother experience at my current settings and having the headroom should I try my hand at some newer games would also be a nice bonus.
@@_shadow_1 a 4070 desktop is miles better than a 3070ti mobile :) You can OC or UV, I would reccomend UV with same performance because OC could give around 10% FPS but at 210-220W while stock performance is achievable at around 150W. Low and stability is good, also depends on RAM and CPU ofc
Great video Bry ✊🥰🤩! Great to see a much better detailed undervolt / overclock video than the variety of less explained videos on the market currently. I used to overclock back in the early 486 AMD cpu days through to the Intel 3770k era ….. after that, undervolting took my heart ♥and been doing that ever since getting into the itx builds just after the Intel 4790k days 🥰👍🥳. Undervolting is underestimated imo.
*Good stuff, I always UV with a slight OC* *For UV I always started off with the -200/300Mhz & never pulled up the lower end to meet/go further beyond the original clocks, so will do that in future.*
Hi Bryan, instead of using a under volt curve try lowering the power slider on MSI Afterburner instead as it works better on Nvidia 40 series. The under volt on 40 series works differently than 30 series as it has a negative side effect of lowering the GPU Video and GPU Effective clock (you can see these in Hardware info 64). By dropping the power slider to your desired wattage you keep all the GPU various internal clock rates synchronized and FPS will be better than an under volt.
i just did that, well i did a mix, +200 on core +800 on memory and limited the power to 87%(not a big saving), so my 4070 can still hit the 3000 core while using 170W-175W max and i'm very happy for the results, of course i could lower the power if i don't enhance the core clock but i prefer this option

Excellent tutorial, best I've seen yet. My 4070 FE wasn't stable at 910mV at 2700MHz, but the tutorial gave me enough understanding to adjust from there and it ended up stable at 925mV at 2700MHZ. Not as good as yours, but it brought it under 160W, so it's still a win in my book.
The msi 4070s boost to 2850mhz. Which is higher than advertised. These cards don't get very hot at all. So with a good case with good air flow it will boost to 2850 95% of the time i found
Awesome man!! Big thanks! I already tried it by my own and was happy about the result but today i changed it to your settings and i was shocked 😂 Before 180watt at 75fps now 130 watt and still hitting the 70fps in starfield @4k!!! Appreciate it!
This mirrors my experience with the 4070. I think I wound up running 2600@900mV just to shave off a bit more power and keep the top freq a bit more stable. Mine is topping off at 150 watts and averaging 130 watts (when using an un-capped framerate). Super useful tutorial, I need to edit mine to bump of the base uV freq as I do have occasional instability when idling.
The 4070 is not stable at 0.9v and the GPU ends up releasing more power than at 0.925 to maintain stability. The sweetspot is 0.95v, and please do not change the curve before 0.950, it will cause instabilities
My Gigabyte Gaming OC RTX 4070 is a pretty wicked overclocker, I was able to go +235 core +1700 memory. GPUz reporting 2800mhz Boost, 1525mhz Memory. This was the highest I could pull in TimeSpy/Port Royal without crashing. The VRM is way overkill on this card. You can crank up the power limit to 148% (320w) which is crazy considering it's a 200w card. Even with my max OC the most I was able to get it to draw was 236w. I wish the voltage wasn't locked down... I run a light OC for my normal usage though, just +35 core +700 memory (2600mhz boost 1400mhz memory). I care more about temps and longevity than a few more FPS.
Thanks for this data, Bryan! Really nice video! I've also looked at the under volting and OC of my 4070 but i have a single 8 pin dual slot card and it's a bit more limited than these 2 8pin configs.
I have a 4070 asus dual OC white, it was already quiet and cool stock, got it solid with +1600mhz on the memory, undervolt +OC not sure how to explain how I did it, 1st I added +240 on the core, and on the curve editor I flatenned everything from 1000mv to the right. This is what I found it to be stable at or lets say the sweet spot. No crashes after several stress tests, core frequency goes up around 2885, with peaks over 2900. Using same power, same temps and noise(same fan RPM, even maybe slightly lower) as stock.
This is so useful when running this card on flex psu with only 1x 6+2pin connector that is rated for 75w + pcie slot rated 75w for total of 150w. This is such a game changer as i can now run undervolted 4070 in my ITX safely.
i do that different. testet a lot rtx 4000 cards. i apply -220on the core, the curve, let it there, tham drag by 975mv up to 2900mhz, that is working an all tested cards and yes 1400 on the memory is also working on all tested rtx 4070 cards. the boost is huge and the power draw is super low 🙂👍🏻 love that stuff
Please do not apply -200 to the core, in addition to causing instability you are wasting energy, if before 1400mhz it was running at 0.700, now 0.700 is running at 1200mhz, it is a waste of power
Mine only starts to run stable at 2700Mhz if the voltage is at 0.925V. It still reduces the power by 40-50W and of course runs way cooler and actually faster than stock. Ingame the 40 Series is just so efficent. My old 1060 ran always at like 110-115W at low settings. The 4070 runs almost max settings with DLSS at like 70-80W. Of course it depends on the game. Once Human on everything max brings the card to like 170W with undervolt!
Cheers for this Brian i learnt a few things from it. I went into the video thinking "meh I'm not your average neck beard i bet i know everything he is going to say". I was wrong.
Hi Bryan, thanks for thsese oc/uv vidoes. Can we get a comprehensive RAM tuning guide for ddr4 please ? Most of newer games push hard on cpu/ram , so it will be very helpful for ppl still using ddr4 to see some performance gains XD
I'm not sure Furmark is a particularly good choice of load, what with it being a special driver case for a number of generations now. I'd probably use a different program, like one of the recent 3D Marks, to ensure that the results are skewed by the driver artificially limiting load during testing.
@@techyescitywitcher 3 maxed with RT (optionally portal RTX) are my go to game for stability. It has translated to stable gaming across other titles. 3dmark and furmark simply doesn't do this. I've done this on a 4070, 4x 4080s, 2x 4090s
Yes, this aggressive undervolt loses almost 2 thousand points in 3DMark, sweetSpot is 0.950v losing only 500 points, it went from 195w to 121W, losing 11°C in the GPU, 6°c in the Memory and losing only 4FPS, with 0.910v makes 119W only 2W difference and loses almost 10 fps compared to 0.950v
Excellent video! I personally like to undervolt so that I don't lose any performance. I've done this with my 2070 super and between undervolting the gpu and overclocking memory I get the exact same performace as default settings where I consume much more power.
My asus dual non oc I couldn't get it below 1.040mv but the power draw is still impressive. Drawing average of only 160w (3k-4k 60 fps locked) , and when I enable Dlss it even goes below 130w 🙀. My 550w psu couldn't be happier 🤗.
Bought my 4070 Gigabyte as a open box from best buy for $459 as a back card for my 4090. Sweet spot for the 40 series power target of %50 -85%. Strange to play 4k 80 fps @ only 90-120 watts with the 4070.
No need to set it manually on that meter when you already set it on the graph. "Curve" means the curve that you have set in the curve editor. If you raise it to 3GHz and the stock is like 2.6GHz, that means you're already applying +400MHz but you're the one who's specified the curve.
Nice video! - With OC you would also like to increase to power limit to get even more FPS - With UV I would mix it with OC so in the end you would end up with exactly the same performance as stock but will less power usage.
I hate this thing where people use some program to test the oc settings but then they say in games it crashes, for example, I've found outer wilds to really force the crap out of my rtx 3060 so why are people not using games to test this lol, you can put games in windowed mode too... So is there any reason to not use a game in the first place and use furmark or such instead?
exactly, the best way to Overclock or undervolt is to play the games you are usually playing, so it differs from people to people and games to games, but benchmarks are the tool to use to see where things are going qickly, meaning how effictive is your OC or UV, fps change, temps change, power draw and etc
Zotac makes great graphics cards for anyone curious. I've got a GTX1070 Mini Zotac I purchased in 2016 and only last year had to replace the fan motor but I just used another fan from a old graphics card to jerry rig it. Still runs perfect and for over 7 years now!
I prefer the frame chasers method: Up clocks by 15mhz Play game Up clock by 15mhz more Repeat till crash Lower clocks 15mhz Flatten curve at stock speed with lower voltage Takes a bit longer but you get stock performance or better with lower power.
I did this with my 4070 super today at 975v , I did try 925v but it was being very glitchy and artifacts where all weird. 975v at 2760 and memory at 1000.
Hello, I should have listened to you earlier a year later, the card began to warm up, the thermal interface became worse, the hotspot is hotter by 10 degrees at the peak of loading compared to the Bulk state, in the future I will lower the voltage of new cards.
Thanks! Just built a ASUS 4070 DUAL SUPER and I was trying to decide if over c or Under V was the best option. I have incredible airflow and cooling with my Fractal case, Especially with Nactua giant dual fin with fan cooler for CPU. I think it runs well enough that Under volt is a great idea, coming into summer.... BUT will save a little OC setting as well, for the winter time gaming😄
adding more info- I thought my high speed fan was from my GPU, it wasn't -the stock CPU fan on my 12400 wasn't cutting it- 40c plus at idle and worse under gaming- switch to the deep cool AK400 digital air cooler and with the GPU changes and new cooler- CPU now 31c while watching this- huge difference- I was crashing 2 or more times playing division 2, thought it was my GPU but it was my CPU running too hot- after doing both the GPU under volt and a new cooler- night and day difference, didn't crash once last night and cool steady- a big thank you
People should keep in mind that the best way to Overclock or undervolt is to play the games you are usually playing or run the professional softwares you are usually running, so benchmarks are only a simple tool to use to see if things are going in the direction you want them to and by how much, meaning how effictive is your OC or UV, fps change, temps change, power draw and etc. You can spend hours testing different numbers and benching on furmark or heaven or 3dmark and etc and then you enter your favorite game and it crashes on the 5th minute. My way of Undervolting is to keep the same(ish) core clocks and undervolt as much as possible while pushing the memory as much as possible. The results are slightly better fps like 2-5% depending on GPU model and silicon lottery and 10-30% less power draw and temps again depending on silicon lottery and GPU model. P.S. Great Tutorial and decent content as always.
I hear that the RTX series are all good for underclocking. What about GTX 1650super, GTX 1660super are these not worth it because of no headroom or is there potential with lower end cards?
what am i missing? i have the same values on the graph on the undervolting and when i hit the checkmark, absolutely nothing happens. idk what to do, i also notice a lot of settings dont really seem to save.
First set the settings, and left click the check mark. unlock the profiles by clicking the lock symbol, then right click on the number to save. If a profile is already saved then it will clear on right click. Click again to save.
Hi Bryan! Great video, as always! I have a question. Is this not too stressful to the memory? Do you have any remarks about memory longevity when applying these overclocks? Thank you!
You should never give up performance unless you are overheating. You can actually undervolt and still overclock you just can’t undervolt as much. Much better solution where you save some power and get a little more performance
Honestly at the numbers shown here, you should always undervolt. You save so much electricity, for a difference you won't be able to see at all. Also running on less power, means less heat and thus increased lifetime of your card. Fps past a certain point are just there to increase your virtual sexual organs, kinda like massive cars. Not going to argue about it, if the difference between undervolt and stock/overclock starts to be in 20 fps territority at under 100fps.
I mean... half of the good coming out of the 4070 compared to the 3080 is that it uses less power so when you get the same fps with 100 watts less power and then come and lower the power even more you are just starving your GPU in my opinion @@peterfischer2039
standartboost on 4070 is arround 2.5ghz, shouldn't an undervolt to 910 and ramping up to 2700 + 1200 mem not be better then stock ? why is everyone talking about lowering the voltage and also loosing 5% ?
I have a Zotac 4070 Twin Edge. When trying to make undervolt below 910mv (flat curve in the MSI Afterburner curve window), the voltage does not go below 910mv. When locking voltage and clock ("L" hotkey in the curve window) below 910 mv, the clock of gpu and memory drops to 405 MHz, at that time GPU-Z and HW-Info display the idle (utilization) state of perfcap, even if some game or furmark is running (of course, performance degrades). How to solve this problem, reduce voltage below 910mv without clock drop?
My psu is 600watt and i have a 4070 with a i910900k I feel like my psu is low for my pc components so should I undervolt my gpu to save it from damage ?
Great tutorial here! Just curious what you'd recommend for MSFS2020? Flightsim has always been more CPU dependent (limited), so I'm curious if this would even help in it...
I always use the Bright Memory Infinite RT Benchmark to test my settings, cause with Raytracing the card has veeery different clockspeeds (4070 Super). I didnt undervolt too much (985mV 2805MHz) but the power consumption still went down from 220->180W. If i go lower I'm getting "Rendering Device Lost" problems in Overwatch with every 3rd driver iteration.
I just leave mine at stock, no idea what the power consumption is for my PNY xlr8 4070, but I do know the average boost clock speed is right at 2790 and it rarely ever varies. temps on my GPU? of course YMMV depending on your setup. I have an old Antec 1100 OG case, and have a nhd15 CPU cooler, so my airflow is weird. My wife would absolutely slay me for spending anymore money on my pc, so m temps of low 70s while gaming are good enough. I suppose I could try to UV, but honestly I just don't have the time(and now that I'm a bit older) and no desire to eek out that extra bit of perf or lower power usage. When I do have free time, I just want to play some games on my pc and only spend time tinkering when a problem does come up(which is rare). Anyway, he has a good guide, almost tempts me to go home and try it, but then I remember that I might have an hour each night and i just think 'nah'
I didn't touch the memory clock or the first dot to raise the bar. I just took the last dot dropped to 2300 and raised 950mv dot to 2700mhz and got better test bench scores. 54 degrees c max, max fps 144 that matches my monitor, min 30 fps. High quality settings used.
When undervolting, I keep getting LIM POW, LIM VOLT and the occasional TEMP LIM. BAck when I was still using my laptop(RTX2080) I just lock it in a frequency and below the voltage to remove it. Now I dont know if it still is advicable with the rtx 4070 ti...
Just got a new PC a few months ago and I’m having this issue now ever since I started playing stalker 2, but it now happens in other games where I’ll have a black screen crash fans will kick on very hard like they are trying to cool something down. And then PC crashes I’ve been reading everything from GPU hardware issues to software issues to CPU issues overheating. I’m at the point now where if it is the GPU the only thing left to do is figure out if it needs to be under voltage or overclocked does anyone else have this issue with 4070s?
I followed the same method, but without any changes you're getting ~190 frames, while my Windforce OC is getting ~160. Not sure why there's a massive difference with the stock performance.
This is the control method, my personal favourite, hopefully you guys enjoy this one!
gross, water cool don't be a bum!

Mine only starts to run stable at 2700Mhz if the voltage is at 0.925V. It still reduces the power by 40-50W and of course runs way cooler and actually faster than stock. Ingame the 40 Series is just so efficent. My old 1060 ran always at like 110-115W at low settings. The 4070 runs almost max settings with DLSS at like 70-80W. Of course it depends on the game. Once Human on everything max brings the card to like 170W with undervolt!
Cheers for this Brian i learnt a few things from it. I went into the video thinking "meh I'm not your average neck beard i bet i know everything he is going to say". I was wrong.
Such a great video!
Hi Bryan, thanks for thsese oc/uv vidoes. Can we get a comprehensive RAM tuning guide for ddr4 please ? Most of newer games push hard on cpu/ram , so it will be very helpful for ppl still using ddr4 to see some performance gains XD
With energy prices as they are right now, power consumption on cards becomes a pretty important metric for deciding which card to buy.
I'm not sure Furmark is a particularly good choice of load, what with it being a special driver case for a number of generations now. I'd probably use a different program, like one of the recent 3D Marks, to ensure that the results are skewed by the driver artificially limiting load during testing.
I have found as long as you don't go too heavy on the MSAA (x8) for example or too little, it can actually be quite solid.
@@techyescitywitcher 3 maxed with RT (optionally portal RTX) are my go to game for stability. It has translated to stable gaming across other titles. 3dmark and furmark simply doesn't do this. I've done this on a 4070, 4x 4080s, 2x 4090s
Yes, this aggressive undervolt loses almost 2 thousand points in 3DMark, sweetSpot is 0.950v losing only 500 points, it went from 195w to 121W, losing 11°C in the GPU, 6°c in the Memory and losing only 4FPS, with 0.910v makes 119W only 2W difference and loses almost 10 fps compared to 0.950v
Excellent guide ,thanks.
What about Zotac 4070 Twin Edge?
I'm guessing if you are customer water-cooled and have good temps then the underclock is pointless as you have the thermal headroom?
Mine crashes when I set 910 to 2700.
Guess I won the silicon lottery backwards
Awesome video. Hope you do one with the 4070 Ti!
Excellent video! I personally like to undervolt so that I don't lose any performance. I've done this with my 2070 super and between undervolting the gpu and overclocking memory I get the exact same performace as default settings where I consume much more power.
god i love this vid, thanks man
I would very much appreciate a guide for the 4080 as well
My 4070 founders edition needs 950mV for 2745 but memory above 1100 is unstable in cyberpunk
Great guide, my Asus DUAL needs .925 for 2700 to be stable, it's artifacting at .910
Great guide, I couldn’t have done it better myself.
My asus dual non oc I couldn't get it below 1.040mv but the power draw is still impressive. Drawing average of only 160w (3k-4k 60 fps locked) , and when I enable Dlss it even goes below 130w 🙀. My 550w psu couldn't be happier 🤗.
4070 in 550 watt rig 💀
Bought my 4070 Gigabyte as a open box from best buy for $459 as a back card for my 4090. Sweet spot for the 40 series power target of %50 -85%. Strange to play 4k 80 fps @ only 90-120 watts with the 4070.
So what was the core clock mhz, +100,+200,?? It just said curve
No need to set it manually on that meter when you already set it on the graph. "Curve" means the curve that you have set in the curve editor. If you raise it to 3GHz and the stock is like 2.6GHz, that means you're already applying +400MHz but you're the one who's specified the curve.
Could you maybe do a Raptorlake, 13600k undervolt guide? I heard those undervolt pretty well
Nice video!
- With OC you would also like to increase to power limit to get even more FPS
- With UV I would mix it with OC so in the end you would end up with exactly the same performance as stock but will less power usage.
Not worth it on the 4070, mine can pull 250w and it only gets 1 or 2 fps more.
I hate this thing where people use some program to test the oc settings but then they say in games it crashes, for example, I've found outer wilds to really force the crap out of my rtx 3060 so why are people not using games to test this lol, you can put games in windowed mode too... So is there any reason to not use a game in the first place and use furmark or such instead?
I guess they are lazy, games can take hours to crash sometimes
exactly, the best way to Overclock or undervolt is to play the games you are usually playing, so it differs from people to people and games to games, but benchmarks are the tool to use to see where things are going qickly, meaning how effictive is your OC or UV, fps change, temps change, power draw and etc
5:30 how do you know there is no memory correction in that oc? You should test and explain that to people, they may lose perf without knowing.
Zotac makes great graphics cards for anyone curious. I've got a GTX1070 Mini Zotac I purchased in 2016 and only last year had to replace the fan motor but I just used another fan from a old graphics card to jerry rig it. Still runs perfect and for over 7 years now!
I had both amp extreme airo and trinity 4090, they are the best 4090s you can buy. Use less power that asus tuf and gainward ghost.
I dont get it. Running furmark stress test and there is a big decrease in Power. When running furmark benchmark the Power consumption are identical 🤨
ur default curve starts at around 1700@700mv, mine is 1500@700mv, MSI Ventus 3x 4070 here. can this be card specific? that big of a difference?
I prefer the frame chasers method:
Up clocks by 15mhz
Play game
Up clock by 15mhz more
Repeat till crash
Lower clocks 15mhz
Flatten curve at stock speed with lower voltage
Takes a bit longer but you get stock performance or better with lower power.
I did this with my 4070 super today at 975v , I did try 925v but it was being very glitchy and artifacts where all weird. 975v at 2760 and memory at 1000.
Hello, I should have listened to you earlier a year later, the card began to warm up, the thermal interface became worse, the hotspot is hotter by 10 degrees at the peak of loading compared to the Bulk state, in the future I will lower the voltage of new cards.
Thanks! Just built a ASUS 4070 DUAL SUPER and I was trying to decide if over c or Under V was the best option. I have incredible airflow and cooling with my Fractal case, Especially with Nactua giant dual fin with fan cooler for CPU. I think it runs well enough that Under volt is a great idea, coming into summer.... BUT will save a little OC setting as well, for the winter time gaming😄
I have the same model, do you have coil whine?
adding more info-
I thought my high speed fan was from my GPU, it wasn't -the stock CPU fan on my 12400 wasn't cutting it- 40c plus at idle and worse under gaming- switch to the deep cool AK400 digital air cooler and with the GPU changes and new cooler- CPU now 31c while watching this- huge difference-
I was crashing 2 or more times playing division 2, thought it was my GPU but it was my CPU running too hot-
after doing both the GPU under volt and a new cooler- night and day difference, didn't crash once last night and cool steady-
a big thank you
I wish you put the numbers in the description
Why not overclock and undervolt at the same time so you get the same performance as Stock but with less power consumption??
People should keep in mind that the best way to Overclock or undervolt is to play the games you are usually playing or run the professional softwares you are usually running, so benchmarks are only a simple tool to use to see if things are going in the direction you want them to and by how much, meaning how effictive is your OC or UV, fps change, temps change, power draw and etc. You can spend hours testing different numbers and benching on furmark or heaven or 3dmark and etc and then you enter your favorite game and it crashes on the 5th minute.
My way of Undervolting is to keep the same(ish) core clocks and undervolt as much as possible while pushing the memory as much as possible. The results are slightly better fps like 2-5% depending on GPU model and silicon lottery and 10-30% less power draw and temps again depending on silicon lottery and GPU model.
P.S. Great Tutorial and decent content as always.
I hear that the RTX series are all good for underclocking. What about GTX 1650super, GTX 1660super are these not worth it because of no headroom or is there potential with lower end cards?
You do have the option most times to get a bit of an overclock while undervolting. I have my RTX 4080 running at 2.8 GHz on 0.975v and it's fantastic
try ion 3d printing (in a vacuum tube) diy chips at home, similar to electron scanning/transmission microscopy, or crt.
When I undervolt furmark ignores it and pushes the GPU with higher clock and temperature
Best explanation
Tried a few 4070's and a 910mv seems to be the minimum voltage for 4070
Bryan said that several times.
what am i missing? i have the same values on the graph on the undervolting and when i hit the checkmark, absolutely nothing happens. idk what to do, i also notice a lot of settings dont really seem to save.
First set the settings, and left click the check mark. unlock the profiles by clicking the lock symbol, then right click on the number to save. If a profile is already saved then it will clear on right click. Click again to save.

How about 4070 super. Could you make a video?
Using the preset at 8:00, my power consumption is still over 200w according to furmark. Also furmark crashed almost instantly.
my furmark fully stops working and freezes completely as soon as i press check at that point, im not sure what i need to change
@@dcgamester.Check your GPU temperature, if it goes over 90°C to about 92-95°C it will freeze. Always keep it under 90°C.
Hi Bryan! Great video, as always! I have a question. Is this not too stressful to the memory? Do you have any remarks about memory longevity when applying these overclocks? Thank you!
You should never give up performance unless you are overheating. You can actually undervolt and still overclock you just can’t undervolt as much. Much better solution where you save some power and get a little more performance
Honestly at the numbers shown here, you should always undervolt.
You save so much electricity, for a difference you won't be able to see at all.
Also running on less power, means less heat and thus increased lifetime of your card.
Fps past a certain point are just there to increase your virtual sexual organs, kinda like massive cars.
Not going to argue about it, if the difference between undervolt and stock/overclock starts to be in 20 fps territority at under 100fps.
My monitor is 165 refresh rate. Doing his settings gave me zero performance loss. Still at 165 fps
I mean... half of the good coming out of the 4070 compared to the 3080 is that it uses less power so when you get the same fps with 100 watts less power and then come and lower the power even more you are just starving your GPU in my opinion @@peterfischer2039
standartboost on 4070 is arround 2.5ghz, shouldn't an undervolt to 910 and ramping up to 2700 + 1200 mem not be better then stock ? why is everyone talking about lowering the voltage and also loosing 5% ?
I have a Zotac 4070 Twin Edge. When trying to make undervolt below 910mv (flat curve in the MSI Afterburner curve window), the voltage does not go below 910mv. When locking voltage and clock ("L" hotkey in the curve window) below 910 mv, the clock of gpu and memory drops to 405 MHz, at that time GPU-Z and HW-Info display the idle (utilization) state of perfcap, even if some game or furmark is running (of course, performance degrades). How to solve this problem, reduce voltage below 910mv without clock drop?
So why didn't you add core clock in the overclock profile and undervolt profile? i don't know much about overclocking or undervolting. Thanks
My psu is 600watt and i have a 4070 with a i910900k I feel like my psu is low for my pc components so should I undervolt my gpu to save it from damage ?
is it ok that undervolt doesn't affect furmark but only other apps?
Gday from Adelaide 👋🔥 Stay Classy Bryan EZ
Great tutorial here! Just curious what you'd recommend for MSFS2020? Flightsim has always been more CPU dependent (limited), so I'm curious if this would even help in it...
I was a bit scared about my kfa2 with 0,910 volt, so i went for 0,950 volt and 2655MHz and 11000 memory and it works fine so far 👌🏿
What are you scared about if less is only safer
Why don´t you put +xxx mhz in all the curve? Also, at lower voltages you can overclock a little more than at higher ones.
I always use the Bright Memory Infinite RT Benchmark to test my settings, cause with Raytracing the card has veeery different clockspeeds (4070 Super).
I didnt undervolt too much (985mV 2805MHz) but the power consumption still went down from 220->180W. If i go lower I'm getting "Rendering Device Lost" problems in Overwatch with every 3rd driver iteration.
I just leave mine at stock, no idea what the power consumption is for my PNY xlr8 4070, but I do know the average boost clock speed is right at 2790 and it rarely ever varies. temps on my GPU? of course YMMV depending on your setup. I have an old Antec 1100 OG case, and have a nhd15 CPU cooler, so my airflow is weird. My wife would absolutely slay me for spending anymore money on my pc, so m temps of low 70s while gaming are good enough.
I suppose I could try to UV, but honestly I just don't have the time(and now that I'm a bit older) and no desire to eek out that extra bit of perf or lower power usage. When I do have free time, I just want to play some games on my pc and only spend time tinkering when a problem does come up(which is rare).
Anyway, he has a good guide, almost tempts me to go home and try it, but then I remember that I might have an hour each night and i just think 'nah'
I didn't touch the memory clock or the first dot to raise the bar. I just took the last dot dropped to 2300 and raised 950mv dot to 2700mhz and got better test bench scores. 54 degrees c max, max fps 144 that matches my monitor, min 30 fps. High quality settings used.
great tutorial
Good video!
what happend if u set low volt and higher clocks on the curve editor? Like 950 locked 2800?
how'd you get all the 2:33 settings so you can see all the ones you want on top?
click and drag
When undervolting, I keep getting LIM POW, LIM VOLT and the occasional TEMP LIM. BAck when I was still using my laptop(RTX2080) I just lock it in a frequency and below the voltage to remove it. Now I dont know if it still is advicable with the rtx 4070 ti...
Just got a new PC a few months ago and I’m having this issue now ever since I started playing stalker 2, but it now happens in other games where I’ll have a black screen crash fans will kick on very hard like they are trying to cool something down. And then PC crashes I’ve been reading everything from GPU hardware issues to software issues to CPU issues overheating. I’m at the point now where if it is the GPU the only thing left to do is figure out if it needs to be under voltage or overclocked does anyone else have this issue with 4070s?
Does undervolting cause gpu any damage ??
why nvidia and amd doest do this default?
please do a video on 4070 super undervolting too
I followed the same method, but without any changes you're getting ~190 frames, while my Windforce OC is getting ~160. Not sure why there's a massive difference with the stock performance.
