I Copper Modded An RTX 3070 Ti. Memory Temperature Dropped 45 Degrees! This Is How. (110C to 64C)

hey hey it's dj and today we're going to be copper modding an rtx 30 series gpu now when i say copper modding i'm talking about these these little copper shims and apparently they're supposed to solve all of our overheating problems on our memory and if you know about the 30 series memory you know that's gddr6 gets ridiculously hot whenever it's put under any kind of intensive load so i wanted to test out little copper little copper squares and see if that magically solves every single one of our overheating issues now choosing to use copper over something like thermal paste is a bit riskier because as most of us know copper is a very good conductor and if you're going to have something conductive touching something else that's conductive well you're going to be having a very bad time i think the purpose of this experiment is to number one not have an exploding gpu number two have much cooler vram temps under load both gaming and mining and number three having something that will last in the long term because you don't want these moving around alas if they do move around we'll run into the shorting issue with that being said i think i've found a way that will be good in the long term and provide adequate cooling all with no issues now before we do any modding at all we're going to run some benchmarks on this 3070 ti just to see how it kind of performs without any modifications to it that way we have some sort of baseline to work off of once it is mod i'm obviously a little concerned here i'm barely even pushing this card and we're already hitting 108 106 degrees on the memory basically that means this sucker needs some new freaking copper shims instead of thermal pads because it just loves to overheat i don't know why there's a few things you'll need before you can get started modding the first are copper plates of a specific thickness the asus tuff rtx 3070 ti has 1.5 millimeter thermal pads therefore i will be using 1.5 millimeter copper plates next you'll need 70 or greater isopropyl alcohol for cleaning the gpu die in the memory modules you'll also need a screwdriver perhaps a few different sizes depending on your gpu the asus tough rtx 3070 ti in particular has a few different sizes of screws next you need kapton tape kapton tape is highly resistant to changes in temperature and more importantly it's completely non-conductive there is absolutely zero risk of this tape interfering with our gpu and its operations at all you'll also need 4 to 5 grams of thermal paste i am using arctic mx4 but any reputable brand should work you'll also want the paste applicator lastly 400 grit sandpaper for sanding down copper plates if they're too pointy some copper plates i have found on amazon have sharp edges which are definitely not what we want so of course the first step is going to be removing the screws to get this back plate off we're going to start with these four screws right here because those ones are directly into the heat sink and through the pcb on these and then we're gonna make our way to of course the little cross plate here and then we'll take out these over here and the gpu should just come right apart the actual process for taking apart your specific gpu may differ significantly depending on its model if you're unsure of how to do that or uncomfortable with doing that then you can look up a tutorial by looking up your gpu name and then followed by tear down and you should find some good results that walk you through exactly how to do it without destroying your entire beautiful back plate or heat sink or whatever if you have trouble getting enough torque on these screws you can always go with the old pliers and screwdriver technique like so it is quite annoying to have such small screws but basically you push down and you twist this should give you a lot more torque to get these small harder to reach screw down one thing you may notice is that the way that i unscrew the cross plate is very specific and that is that i go one across two over that is if you were starting in the top left you'd go top left bottom right top right bottom left alas there's just a few more screws to undo until we finally get the great reveal and this right here is why i was so specific on wanting to use this asus tough gaming 3070ti versus a different gpu you can see that there is actually a sub heatsink that is exclusively for the memory and this is both a blessing in the sense that it tells us or will tell us very soon whether or not our copper plates are positioned correctly but it's also not great for cooling not even gonna lie it's probably the reason why we were seeing 106 plus degree temperatures earlier next we're going to undo the fan wires or whatever connectors they may be and we're gonna focus exclusively on the pcb itself okay so basically the plan here is to remove these pads you can see that they're a little ripped we'll just get them cleaned up here remove the paste and then we're going to surround these gaps around the memory chips with kapton tape you can see here i've got three different sizes and we're going to put that around the outside of the chips so that we don't short any components such as capacitors or resistors you can see if you look really really closely here there are components all around the outside of these chips we do not want to short those with our little copper shims here and so begins the somewhat arduous and somewhat annoying process of removing thermal paste thermal pads from this entire gpu i won't lie i don't know of any better way to get it off of this gpu because the pads were literally stuck on there like glue and every time i tried to remove them with my fingers they would just rip immediately which is really great because i did want to reuse these but you know i guess you get what you pay for and i'm not really sure what i paid for here judging by the fact i was getting 106 degrees celsius this is where that isopropyl knot for drinking alcohol will come in handy as you can see i just apply some to a shop towel and i wipe off the gpu die and i try to get some of the thermal pad residue off of the memory you'll see the end result in a moment but it's not too great that's okay though if there's a little bit of what looks to be like pieces of thermal pad still all over your memory i can assure you it will be fine it will not cause any thermal issues in the long term this is where we finally add the captain tape now there's a few different ways you can go about this i personally start from the inside and try to work my way outwards filling in the gaps as i go the way that you choose to go about filling in all of the gaps doesn't really matter it kind of more depends on your risk tolerance i for me do not want to be taking any risks therefore i filled in every single gap around the memory chips if you look very closely you will know that there are some components that are sticking out a little too far for comfort and those are the ones that we mainly want to be covering up with this captain tape to err on the side of safety you will see that i place captain tape completely around the outside of every single memory chip so that there is no possibility of making any kind of short anywhere the next thing i do is a test fit of the copper shims i kind of want to get an idea of where i want to place them before i actually put them on the gpu i'm not actually applying them yet so you see there's no thermal paste no anything this is simply a test fit to see where they should be going and if i need to make any adjustments after that test fit you can see that i definitely didn't err on the side of extreme caution and add even more freaking capped on tape is it capped on or is it captain you know i'm sure you guys can argue about that in the comments anyway this is the finished actual result for the camp on tape there is no more to be added and that means now that we've test fit we can move on to prepping our wonderful little copper shims for usage unfortunately my copper shims did come with some pointy edges so i'm just going to run over them for about 10 seconds on this 400 grit sandpaper and then after we've run each one through the sandpaper we're going to wash them off because look at this you can see there is copper dust all over these shims now and what do you know about copper dust it is conductive if this copper dust ends anywhere on your gpu it's basically game over so give them an extremely thorough wash wipe them off make sure they're dry and get ready to install them into your gpu we're going to be applying a generous amount of thermal paste to each and every memory die right on top just like you would the actual gpu die and then of course we're gonna put some on the gpu die as well because well if you don't it's going to turn into a fireball anyway do that and then next you're going to spread it all around with the thermal applicators until it's nice and even across the entire surface this is a very messy process but it is necessary so get to pasting and now it is actually finally time to add the copper shims we're going to put the copper shims on each and every spot where there is memory right on top of the memory where we just applied all that thermal paste one thing you'll notice is i do most of the copper location adjustments here because this is the most convenient time to do it while you can do it in the future i would advise that you do it here because the next few steps get especially messy and especially irreversible unless you want to mess this all up yes we are now going to add yet another layer of thermal paste but this time we're not going to spread it out that is going to be the job of the heatsink or in this case the sub heatsink dedicated to the memory you'll see in a moment when we put it on [Music] so one thing i figured i would do is a test fit with the sub heatsink attached you can see that i screw in two screws and then i verify the location of each of the pieces of copper i don't tighten it down all the way and i move the copper in just the location that i want it of course it's very important that i do this now because this is the last time that i'll ever get to move this copper unless i want to mess all of this up now believe it or not the modification is basically already finished now we just need to completely reassemble the card and we'll get it testing [Music] [Applause] [Music] and after a tremendous amount of pain and stuff i mean labor i present to you the copper modded rtx 3070 ti you know it kind of just looks like a normal 30 70 ti whatever anyway the point is that this has copper inside of it and not thermal pads so we've just started up here see we just loaded up t-rex we're at 41 and 60 sitting still at around 62 now i'm gonna wait for this to calibrate maybe give it five or ten minutes to mine we'll come back and look at the temperatures then okay look at this 57.29 mega hash it's not clock as high as it could be but look at that 45 on the core 64 degrees celsius on the memory you can see here in gpuz 64 degrees celsius that's a huge freaking difference like that's incredible you can see here we got copper and it's it's literally night and day i mean where we were getting 110 degrees 64. that is literally incredible i'd like to believe that the results here completely speak for themselves if you're struggling with a 30 series gpu and you've tried paste pads and just about everything else you can think of it may be time to consider copper modding and that's not to say that it's for everyone after all copper modding carries an innumerable number of risks that pads and paste doesn't however you saw 45 degrees celsius reduction in memory temperatures that is insane and it's not like mining is the only application whenever you might have to do this i know that personally whenever i'm doing something like an intense cycles blender render my memory dies in my 30 80. so even for someone who's just a workstation user this might be a good idea for you especially for creators like myself in fact i'd kind of like to know whether or not there's other people crazy enough to try this that it's not just me so please leave a comment if you do decide to try it and tell me what gpu you are trying it on anyway that's it from me i hope you have a wonderful rest your day or night or whatever time it is for you
