He was an engineering undergrad, who watches a lot of KZbin videos of actual engineers. He thinks if he watches those KZbin channels, uses their terminology, and gets Linus to buy him the tools that they use, that he can do actual engineering and fabricating. That half a million dollar shop with $150k worth of welding, machining, and fabrication tools and machinery, and he can't even solder a resistor on to a PCB. Everything he does turns out like trash. He couldn't even get the chiller to do anything more than look pretty with a laser cut sheet metal case and some LEDs. They need to get an actual engineer/fabricator on the payroll. He's just not it. It took him like a grand worth of cast acrylic and days (over several weeks) worth of labor just to machine the reservoir for the desk PC. He made like 20 failed prototypes. I don't get how or who he convinced that he has more abilities than he actually does. Had to have been Yvonne. Was an engineering undergrad, you learn almost zero engineering skills, and next to no fabricating/practical skills. It's mostly math and physics classes and that's why you don't become an engineer just because you have an engineering degree. You need to work at an engineering firm to become an engineer. Like doing rotations and residency to become a physician. He's like most engineering students. They may do really good in the physics/math classes, but couldn't screw two pieces of wood together. But I suspect that he didn't do good in classes either, considering he didn't finish.

[@Jibberish81]

Yeah that was some of the worst soldering I’ve seen in my entire life. They go through all the effort of making a video about overclocking a card that very few of us can hope to obtain right now, and then just haphazardly glob some solder on the board, talk about how they could have done it correctly, and then just call it good for the lol’s. They didn’t even bother to use any cleaner on the board when they were done. Also, if you’re just going to solder another equal value resistor in parallel to cut the resistance in half, just desolder the original resistor and install a half value resistor. That would have been much more simple.

[@Jibberish81]

@@robertbrainard5651 That Hakko wasn’t really a bad soldering iron. It’s no Metcal, don’t get me wrong, but it’s not bad. Their big problem, as they correctly pointed out, was that the board was doing a very good job at syncing away the heat faster than the iron could heat the solder joint. They’re just too freakin spoiled and lazy to follow their own advice to preheat the board before soldering, or take other measures to get enough heat into the board fast enough to properly heat/flow the joint. I used to solder at an aerospace company and this heat dissipation issue is not anything new. They’re just lazy and spoiled.

[@han5vk]

@@Jibberish81 I share your frustration. I'd say desoldering the old resistor is definitely not easier though, at least in my experience. You run the risk of ruining the pad, and even if you don't you gotta clean it and all that. Piggybacking on top of the old one is faster and easier. Especially considering you have less thermal mass to heat up with more thermal resistance to the board, fighting its heatsinking capability.

Not surprising, the non leaded solder is suppose to take a higher temperature to melt, it saves the planet and your graphics card from dying. But is impossible to work with as leaded and unleaded solder don't form good joins, that's why Louise removes it and starts fresh when rebuilding a circuit.

[@israelmxc]

It doesn't really save your GPU, good old leaded solder is actually way better (in therms of long lasting lifetime) modern electronic solder joints can easily fail within 5-10 years while old school stuff still works. As far as I know its just a thing of saving money more than a enviroment or safety thing. Leaded solder must be worked with active air suction. If not the companies are legally accountable for medical problems. So not leaded means no legal responsability and saving money on not needing air extractors.

What I want to know is, if you stuck some passive heat sinks on basically everything that makes heat, then put the card outside on a bitter cold day (or maybe in an industrial fridge) with some blowy-mactrons maintaining air circulation; how much of an overclock could we get?

[@Incommensurabilities]

I wonder if really cold, high-velocity air would have enough thermal mass to cool the GPU die using a passive heatsink. Everything else would be fine

[@WorldLaughsWithYou]

@@Incommensurabilities The thermal conductivity of air is very low, it would do well in a hydrogen environment as well as eliminating the concern of condensation.

[@petervernia5074]

FYI, Weller sells tweezer irons for these types of SMD resistors. They heat both ends of the resistor at once, and keep it from sliding around.

[@phlooke]

Now that sounds like something I should have bought or invented 10 years ago, I must have one

[@Spritetm]

Those are not super powerful though... probably wouldn't have worked to heat the solder up enough with that huge GPU ground plane wicking away all the energy.

[@derekcheyne7066]

Also were they in “A” or American mode or C? Im curious if there temp wasn’t actually the temp they thought. Or someone fiddled with it and accidentally reset their calibration curve. Ive seen that in more than one lab before before and you had to reset it to factory settings on those hakkos.

[@tiegert1]

These are garbage, the best solution is to use a heatgun to warm up the board and then use two soldering irons so you can connect both ends at once.

[@Robertkopp84]

2 times 40 watts are maybe enough to get some wieners hot. And you can get the big jbc with 2 irons for the price of a micro tweezers set.

[@kajin807]

Alex + overclocking = this is gonna be an amazing video

[@vitor900000]

4:05 You can also remove the old shunt and solder a single new one with a smaller resistance. In the your case that you want to increase the power limit by 100% all you have to do is solder a 250mΩ resistor. 100% is a lot more power so If you want be more conservative you can REPLACE the original resistor with one those resistors instead: 4.5mΩ = ~11% more power 4mΩ = ~25% more power 3.5mΩ = ~43% more power 3mΩ = ~67% more power 2.5mΩ = ~100% more power

[@BeatsbyVegas]

If you aren’t running a modified bios/ hard modding the component its extremely difficult to damage things with overclocks. You have more control with cpu overclocks so you can technically crank way too much voltage and fry your chip, but killing a graphics card via just changing sliders in something like msi afterburner is almost near impossible. If a gpu dies after running it at the highest allowed power limit then it wasn’t long for this world, and it would almost certainly have died under more stock conditions pretty shortly after anyway.

[@rasmust8044]

@@rasmust8044 you are not likely to fry a cpu by entering too high a voltage and POOF the magic smoke, but within a couple months that thing will be toast.

Quick nerd trick for soldering! Melt the soldering wire above cold hard surface like a metal block or tile. When it hits the droplet will flatten. Use scissors or snips to cut a nice strip to lay between your contacts. Apply a little flux between the contacts and your solder strip. Downward pressure from and apply heat. no mess!

[@Derragon]

Honestly a heat gun works quite well for this - if you are able to set it to a lower speed and use a finer nozzle you can replace SMD components quite a bit easier (and safer) than using a toaster. I think you could do it with the Hakko (I have the exact same unit myself) with a high thermal mass tip. The one you guys were using looks pretty light for that sort of PCB. You can also try pre-heating the board to assist the soldering iron in the future (so you're not bringing the whole thing up to temps that can damage components).

[@hernerweisenberg7052]

I also had good results with those plier type soldering tips that grab the component from both sides, put a drop of solder on each end to use it for thermal mass and just place it ontop- done.

[@jthomas.]

Those soldering skills though... For those blaming "cheap" equipment here, I assure you that was absolutely not the problem, simply a lack of training/experience. I would highly recommend taking a community college soldering/assembly class or at least studying the old Pace videos. Like most, I always thought I knew what I was doing too. Once I took a class at JC, I learned how wrong I had been doing it. Now, I can make pretty (and reliable!) joints with even the cheapest Weller firestarter.

[@acatch22]

yea it looks like they didnt have advanced experience but idk if i agree about equipment not being the problem I had a quick certification training at a manufacturing plant I used to work for. With proper equipment i was able to do some pretty good soldering if i do say so myself. tiny smds, super thin and close processor pins, bgas. At home, i tried to unsolder the broken power jack on my laptop, i was using a $10 iron with no temperature control. With unleaded solder it was pretty much impossible to unsolder it because the iron just did not get hot enough, along with the fact that the jack was acting as a heat soaker, the solder just didnt want to melt. i spent 3 hours trying so I bought a cheap but adjustable iron from amazon and i was able to do it in less than 5 mins. my point being, if your iron doesnt get hot enough then unless your a real expert. its going to be really hard if not impossible

[@ActuallyHardcoreOverclocking]

if you don't have a powerful enough soldering iron the only thing that will save you on high power boards like GPUs is a ton of preheating(PCB at or above 100C).

[@ohne_speed]

I would say both... We have very good equipment at my workplace and it's simple sailing to solder even with 6-8 layered boards and huge groundsinks. While when I have to do half hard stuff at my crap-mediocre soldering station at home, it is a struggle sometimes.

[@jeremyfernicola6985]

I have one of those Hakko digital soldering irons; in fact, they are not cheap or unreliable. If I'm not mistaken, by holding down the adjustment buttons you put the iron into calibration mode where you can tell it what temperature it is running at. That is a sure-fire way of making it too hot/never gets hot enough, depending on how you adjust it. Been there, done that, got the t-shirt.

[@recoilrob324]

I was trained and certified to do military grade soldering on ASW equipment....but they used lead based solder ONLY. The 'lead free' stuff is absolute crap and the US military won't use it which causes the EPA to give them grief all the time...but the prints specify the solder and it ain't lead free which takes WAY too much heat to melt. I hate the stuff, but anything consumer available now a days will be lead free which is a pain in the ass IMHO.

[@TheOriginalFaxon]

Wow, I have that iron and I've never had nearly those problems soldering things that sink a ton of heat, i've even used it to repair video cards that had SMD caps knocked off of them. When I ran into finicky spots, i'd use a hand held butane heat gun to heat the area around the joint for a few seconds, and then id pull out my iron and go to town. Generally this wasn't needed though, I just fluxed it heavily and then got a nice glob of 60/40 on the end of my iron, and then cleaned it up after if necessary. Yea, sometimes it's a bitch on surfaces that sink heat particularly well, but I've used that iron to solder things with a lot more thermal mass than a 3090 PCB

[@ProjectPhysX]

@@alexanderclark6889 yet if there is liquid solder on the soldering iron tip and fresh solder/flux on the connection, a liquid bridge forms upon contact and the heat flux through the liquid solder is enough to melt all the remaining solder on the pad.

@@alexanderclark6889 Use a heatgun to preheat the joint, put leaded solder on the joint and wick it up right away, then replace with leaded solder. Also moving forward get yourself an iron like the FX-951. Tips with thermistor + heater core are so much better with heat soak.

[@renchesandsords]

In my experience soldering to power planes, a lot of those style of soldering irons suffer from the heater cor not properly touching the coper tip, so the core isn't directly heating the tip. I've have much better result shimming the PCB inside the iron so the ceramic core sticks out more and butts up againts the base of the tip, I also add some liquid metal to the inside of the tip to help with thermal coupling

[@AsdfirePL]

I got a cheap aliexpress iron that uses T12 tips (Integrated heater, sensor and tip) eliminating this issue. It's also quite powerful (managed to solder 6mm2 wire for testing, the power is 120W and it also has some controller that is not dumb and gives more power if it sees temperature dropping to maintain it. The tips are kinda expensive 4$ each but then how often do you change tips.

[@daskadse769]

​@@AsdfirePL Honestly, a mid-size company like LMG could and should probably just go for some professional brand iron (be it JBC, Weller, ERSA or something else). They're expensive, and you're easily gonna be out up to 1k for a station and a few tips, but compared to salaries or other business expenses that should be very doable, and you get decent warranty and service on top (which is valuable in a business setting). For personal DIY stuff aliexpress irons are _probably_ fine (unless you have bad luck and get one that randomly catches on fire or exposes mains at the tip), though I personally would still prefer to DIY something like a unisolder as a cheap but good PSU/station and hook up JBC irons and tips to it (mainly because I really like them). When going for bang for the buck, there's also the miniware irons (TS80/TS100) which are great value and handling (low grip-to-tip distance) and really do hold up even on large ground planes.

Suggestion: do a video on why overclocking works to begin with. It's far from obvious for many of us. Why would giving more voltage and current make it faster instead of simply hotter or more smokey? The clock must be involved somehow given the name, but the actual technical mechanism is not at all clear.

[@paidlogic]

Overlocking is literally changing the clock speeds higher than stock. Typically to do that you need to overvolt as well. Doing that causes more heat due to conductivity.

[@nem3sys]

Higher clock speed = more data processed faster. This consumes more power, meaning it then requires more voltage to be stable under load. This then produces more heat, which must be dissipated effectively or the card's thermal protections will throttle back the performance. How much wiggle room you have in each of those factors, and how much measurable performance you gain from it, varies hugely between models, and to a lesser extent even between the specific piece of silicon your card has vs another of the same model.
