    RTX 3060 Ti broken capacitor

    It's real easy to knock them off if you get liquid metal on the solder. The liquid metal dilutes the tin in the solder and makes it soft enough that you can just knock those little caps off. In other words, the kapton tape or nail polish isn't just there to keep the liquid metal from creating...

    High End Graphics Card Stock 6900 XT vs 3090

    For those in the market, Newegg has the Asus TUF 6900XT for $1599 today. That's $50 lower than the lowest price I've seen on a 6900XT previously that I could easily just order and receive without the need to camp outside of Micro Center like some sort of dystopian cyberpunk hobo. So, at least...

    RTX 3060 Ti broken capacitor

    It's cool, man. There's a Youtube channel out there with my real name on it where I talk about this sort of thing into a camera - if I didn't want to be asked, I wouldn't be screaming the answers to these questions into the void. My real job is mostly unrelated to this. I've wondered in the...

    RTX 3060 Ti broken capacitor

    Truth. I've not had the pleasure of examining an Ampere card, but on older designs, the function of those little caps is to filter noise out of the memory power supply. I happen to have the equipment to do it, so I'd replace it, but there is a strong case to be made for just leaving it alone...

    RTX 3060 Ti broken capacitor

    Step 1. Figure out which circuit that capacitor is part of. I think there are three or four on Ampere cards: * GPU Core power (should be about 1.1V) * Memory Power (should be about 1.3V) * Auxiliary rail #1 * Auxiliary rail #2 I'm not sure what the auxiliary rail voltage is, but it should be...

    RTX 3060 Ti broken capacitor

    It's not so much the model that you need as the capacitance. What I would do is use a real fine nozzle on my hot air station, and remove one of the ones next to it, measure it, and then put it back on. I can't say for sure without measuring, but the physical size is likely either 01005 or...

    Graphics Card too Cheap to be true

    Given that the memory voltage appears to be a little high, I think I'd be checking for corrosion or damage on the sense pins for the memory power controller. Hint: Look up the datasheet, and use it to figure out what the resistance on the sense pins should be. There's usually a formula.

    Safe to run GPU without VRM heatsinks?

    It'll be fine. I'd probably try to get some heatsinks on there for permanent use, especially if the idea is that you're going to mine this card to death, but if you're just testing to see if the system will work at all with this card in there, it shouldn't be problem. The metal casing on those...

    Where can I get a GPU Fan cable Y Splitter?

    Are you handy with a soldering iron? This would be pretty simple to make. I’d probably splice in a SATA connector to get the 12v from, if you’re adding extra fans.

    Alright, so your memory and controller aren't running either. As I recall, the memory power has its own controller. I didn't have to investigate this, because my problem was elsewhere, but I suspect that what happens is that the enable signal for the core and memory controller only comes alive...

    Graphics Card Necromancy - Sapphire Radeon R9 390 Nitro

    The 3.3V rail shouldn't ever be zero. It's supplied by the power supply. If you really have zero on that one, you need to figure out why. First, are you SURE that you're measuring the right spot? The best place to access it is the shunt on the back of the board near the display connectors...

    980 ti advise

    I would advise against cannibalizing the FDMF6823As from a used board. They fail because they ran too hot over a long period of time, so a used one may be worn out anyway, but also, they're very easy to damage when you remove them with hot air. Be patient. Get new ones.

    980 ti advise

    Probably related to the VRM. Fix it fully and then troubleshoot further if you need to. Consider yourself incredibly lucky if you were able to solder one of those FDMF6823As on the first try.

    Sapphire rx470

    The big pads in the center are probably supposed to be connected, since they're both ground. It's pretty common to see that pads for pins that do the same thing are actually connected like that, and then the coating on the board is used to make them look separate, and get the solder to make...

    Sapphire rx470

    Use more flux - get better flux if you need to - and a soldering iron to separate the pins. Clean the tip, heat each pad and soak up the solder, and then clean the tip. Repeat a bunch of times, being careful not to overheat the pads. As I recall, Amtech flux is supposed to be made in New...

    Your Google-Fu is weak. ;) As it happens, I have a few of these 980 Tis lying around. The only one that works and has the Samsung memory chips shows 13.8 ohms to ground on the memory rail. The card in my thread about the 980 Ti Classified that you alluded to in your original post shows 9.xxx...

    Sapphire rx470

    0.6 ohms is a bit low for a GPU this small, but not necessarily a short. Now that you've cleared the short, the card should probably work, but I'd advise replacing any components you removed first.

    GPU Suggestion for while I wait..

    Just a thought: Radeon 290Xs are going for about $150 on ebay. It's still kinda steep, but not as outrageously expensive as most other cards, and it's a way more powerful card than the GT730. I know you said you wanted to buy new, but I'm not sure you'll like the experience of playing Skyrim...

    I like the radiant ones, myself, like the Aoyue 866. I've never seen one that used forced hot air like a heat gun. The hot plate type ones probably wouldn't work that well for graphics cards. I've repaired a few graphics cards using just hot air, and smaller cards like the 470 may be a little...

    Graphics Card too Cheap to be true

    The first thing he should do is make sure the card has the proper BIOS image, if there's any suspicion it might not. This requires knowing what "brand" of 980 Ti this is. Download it from TechPowerUp and use nvflash to compare it to the one on the card. My guess would be that they'll match...

    Graphics Card too Cheap to be true

    First, 150 degrees Celsius isn't hot enough to reflow the solder on this card. All you did by "baking" it was (probably) make the problem worse, whatever it is. In order to reflow the solder, you would need to get the solder up to at least 225 degrees celsius. Do not attempt that - it won't...

    Sapphire rx470

    If there's no visible damage, it's kind of unlikely, but there is a mode of failure where the FETs get so hot after they fail that their terminals actually weld themselves to the copper in the board. In these cases, no matter how hot you get them, you can't remove them without also lifting the...

    Gotta get the board hotter. Either warm it up with a heat gun first or use a real PCB preheater. It makes a huge difference.

    Sapphire rx470

    It's possible that being subjected to 12V damaged the GPU, but there's a pretty good chance that it didn't. I've seen a lot of cases where the GPU worked just fine after clearing the short. You need to use your knowledge of how the VRM circuit on the board works to figure out which FETs are...

    Advice on components to purchase for 2080ti with Byliski block

    The size of the reservoir doesn't really matter, but the size of the rad(s) does. A larger reservoir will give you a bigger coolant volume, increasing the time it takes for the temperature to reach equilibrium, but this will really only be a difference of a few minutes. Thermaltake makes a tube...

    Sapphire rx470

    Check for continuity between the spot you soldered the wire and the output of the GPU core VRM. If you have zero, then most likely you have a high side FET failure. I'd just start removing them until I cleared the short, and then replace all the FETs I removed. Use a preheater to remove and...

    I don't see anything out of place in those. Check the fuses for 0.000 resistance, though. You should have a total of five, I think. The next step is to hook the card up to the system and check each power rail for the expected voltage. A setup like I showed in the photos in this thread is...

    GTX 1080 strix no output / 5V rail missing

    Your problem is definitely not those capacitors. Remember, you have a short from one power rail to another. The capacitors should never be connected to more than one rail. The controller is most likely the square component to the right of the core phases - the one not labeled "ITE." The one...

    Ok, so if you have less than one ohm of resistance between the memory power and GPU power, that means you have some sort of catastrophic failure somewhere. This can occur in a few places, but the most likely is the GPU die. The second most likely possibility the PCB itself. A remote...

    Yes. In the picture you posted, the two large inductors at the top of the row are for the memory power rail. 0.9ohms is probably a short. You should have at least 30 or so, as I recall. So, your next step is to hunt for a short on that rail.
