@@vojtech1797 please, northridgeFix will replace also the connectors(and repair up to 2-4 broken pads, if needed). In the past he was putting more effort in repairing and diagnosis. With fame, more work came, and he cannot scale his bussiness. So he takes the "easier" work and charges more for it. But overall, is a very talented technician. It's solder skills are better than northwestrepair. But for gpu repair and knowledge, northwestrepair is the master.

[@handyman1957]

Wow man, that's a serious deep dive in to that board. Mad respect, my hands would shake too much to do that kind of work. Truly amazing you can even fix such complicated multi layer boards like that. True talent : )

[@Alvin853]

On the 3 vs 4 connector adapter: Each connector is rated for 150W. Base model 4090 are rated for 450W, so 3 connectors are enough. Some higher tier cards are rated for more power, so they need a 4th connector to supply all that power. The 4 tiny pins on the side are for the card to detect how many connectors are actually plugged in, so plugging just 3 cables into the 4 connector adapter will limit the card to 450W mode.

[@Jasontvnd9]

What about the 75w from the pcie slot?

[@Alvin853]

@@Jasontvnd9 on the big cards the major components usually run fully off the cable. The slot power may be used for stuff like fans, LEDs, possibly audio controllers, HDMI/DP encoders etc. You can't just combine the power from the slot with the power from the cable, and dynamically switching based on load is very complicated, so it's easier to just run everything off the cable. Lower end cards might run the core off the cable, but the memory off the slot, to spread the load a little more and not require too many extra connectors.

[@HarmonRAB-hp4nk]

theres no pins on that tab, its the lockdown tab... great job fooling everyone but a pctech of 25_ years :-)

[@talon1706]

@@HarmonRAB-hp4nk Lol. Good one. 25 minutes?

[@Xanderfied]

Also most cards unless youre talking a modem or some Wi-Fi adapter tend to have dedicated power adapters so as to assure the device is powered correctly regardless of the load on the board or cpu. Kind of a cover our asses clause built in to the component. At least since pcb slots have become more versatile in the type of hardware they can accommodate.

[@HarmonRAB-hp4nk]

its the card retention tab.. no electronics in it lol

[@jarivuorinen3878]

@@HarmonRAB-hp4nk No electronic components, but on multi-layer board this kind of crack creates huge problem, and that is why the wires are essential he put in. And the way he laid them is essential too. PCI-E protocol is very strict on timing. Basically all the connections in the PCI-E slot must be exactly the same length, otherwise the protocol doesn't work. Latency isn't a problem, and this is why something like riser card can work. One could say that yes, there are no electronics in that tab, but there are signals running in the copper layers inside that tab. The phase difference the crack created in this particular card propably messed up relative timing of the signals, so some signals took longer to go around that crack made the card non-functional.

[@NewRetroRepair]

FYI, CW2500 is great epoxy for these kind of cracks. It won't soften as the card heats up like regular 2 part epoxy.

[@jarivuorinen3878]

Wrong. Properly treated epoxy will harden, not soften when heated. Final hardness after initial curing is achieved by curing the epoxy in 60-100 celsius, but after the baking epoxy can handle higher temperatures. Of course there are many different formulations for different use cases that have bit different chemistry going on, but the process is the same for all epoxies. Even PCB has epoxy as matrix, and this guy on the video bakes these boards for extended time in 200 celsius and even more when soldering, and PCB can handle it just fine.

[@AI_MicroSolder]

Fantastic work!! You asked why there's 4 wires for the 4090. There are the 8 main pins and 4 small since pins. If the card senses that there is only 3 cables plugged in . The card will limit the the amount of power available to the card. If it senses all 4 main power cables plugged in. It will allow for the full 600 watts to be available. That includes the 75watts or so from the PCIE lain. Nvidia has a video and so does Jay's Two sense. They show how the sense pins do what they do to protect the card and the stupid plug they started using. Thank you for all your videos! I'm going to tool up and start learning myself. You help tremendously and im very thankful for you putting all the time in and sharing your ways.

[@Aliens308]

Concerning your expieriences with the hardness of cured epoxy glue, at least with the ones im using, those that take longer to cure are better. The german made UHU Zwei-Komponentenkleber plus endfest 300 is a 12 hour glue that can be cured at up to 180°C for 5 minutes, and gets you a rock hard result. Also on the back of the packaging one can find a chart for curing times at different temperatures and the resulting hardness. For structural support, I always use some kevlar fibres, I salvage the kevlar contained in fibre patch cables, then using good a pair of scissors, I cut the fine strands into small pieces and incorporate that stuff in the epoxy resin before applying it, It also thickens the epoxy so that it gets less runny when heated.

The spec for PEG8 has a range of acceptable wire gauges. Some of them arn't enough to carry 600W with just two connectors. Since nvidia can't know if you have high gauge or low gauge wire, they have to assume the worst and send dongles with additional connectors.

The design of the PCI express system needs to be completely redone, it was designed for cards that weighed from a few ounces to a couple of pounds, now some of the cards need an industrial crane to be lifted, and the way it's going I don't see that trend changing anytime soon. Cracked PCBs around the tab will be a dime a dozen in the coming years.

[@jessicahunt6569]

the reason for shrinking the pcb even if its in a huge cooler, is that you can get more pcbs in one panel, reducing pick n place and other costs with manufacturing... aka they're cheap

[@pcbuilderlover4271]

Awesome repair videos. You may or may not know 5 minute epoxy dries hard as glass and can crack under extreme vibrations. 15 minute epoxy always stays just slightly flexible. Not that this video card wound undergo any vibrations. I fly R/C airplanes and helicopters and vibrations vs epoxy type make a difference. Just one irrelevant probably useless info for you. I also for a living was an electronic repairman. So I find your videos extremely interesting. You have some real nice equipment too. 👍

On such a large core wouldn't it benefit to spread the thermal compound out like icing so that way no area of the core gets missed.

I have a gigabyte 4090 OC edition from launch day. So far the connector has not melted or even shown any signs of issues. I noticed a month or so in, that I had SERIOUS GPU sag. I bought a gpu sag stand and jacked the card up until it was level. I am just realizing now that since I got the GPU stand, I was experiencing occasional random reboots. Only when light duty GPU work was being done. I relieved some of the tension on the card and now have the stand supporting it in a slightly sagging state. Random reboots seem to be alleviated. Long story short, I will keep watching these videos, and I know where to send my card when not if I have a problem. Or my motherboard, whichever gives in first.

Yeah not sure why they insist in making the 4090 so big, All the ones I've messed with you run pretty much any stress test and the things hardly go above 70C at 60 - 70% fan speed they could have easily made the card smaller and lighter, but I guess at the price point, they got to make up for it somehow... Good work either way, amazed how you were able to actually get that card working!

[@PineyJustice]

As a hint, nvidia doesn't calculate hotspot temps the same way AMD does, AMD hotspot temps display raw hottest sensor output while nvidia uses a formula to average, both are limited by mechanical properties, so real hotspot temp needs to stay below 110 or so, more than likely this is required to keep the true hotspot temp below that number.

[@teddp]

Hallelujah, you finally fixed it brother 😁
