    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...

    Looking for a good asic miner repair service in USA

    Are the chips available? Can you post some photos of the damage?

    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.

    How often do you replace power supply?

    When it starts killing graphics cards.

    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.

    Graphics Card Necromancy - Sapphire Radeon R9 390 Nitro

    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

    Ok, so the core rail isn't running. What voltage are you seeing on the memory and memory controller rail coil terminals?

    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...
