  • What do you expect from running 10 and more amperes through a cord?

    Well , I expect enough engineering behind it that the cord and connections don’t melt. I am an auto electrician, I routinely deal with 12v systems that draw much more than that without melting, using connections that aren’t much bigger. It’s not like it’s some mystical technology, it’s just that this setup has been done on a budget.

    But it doesn’t help that every single logic gate in a graphics card is run at a speed/currents that are literally just below meltdown.

    People don’t just leave leaking apps out there for consumption.

    Ha! Welcome to corporate, where vendors sell you software and say that the hardware has to have 128GB of ram and when you poke around a bit you discover a single JVM with constantly growing memory usage with a script that restarts it every time it runs out of resources.

    AND a log file that describes - in typical Java excruciating detail - the precise lines in each module where the devs allocated resources but didn’t free them. About 40 times a second.


  • It’s only one wire in the cable, and it’s not the wire, but it looks like the pin, or possibly the crimp point on the female pin.

    So a few possibilities:

    • Bad pins. Female pins (sockets) have internal wipers that grip the male pin and there is also the crimp connection. Bad QA on those leads to hotspots in the pin under high current draw. I’d probably go for this explanation, looking at the photos.

    • Bad electrical layout on the card that means that the bulk of the current goes through this pin. Milliohms on the track traces are enough to cause imbalances. This might be balanced out by having a small-but-still-larger resistance in the (standard) cable, which leads to:

    • It looks like thicker cabling is soldered and heatshrinked to smaller cabling that actually goes into the pins in the connector. There’s a reason why industrial cable connections aren’t soldered. Possibly a solder connection on another cable has broken and hidden in the hearshrink leaving more current to pass through this one.

    • Following from this it’s also quite possible that the thicker cable with less resistance , now has less voltage drop across it, and simply allows more current then designed through a connection already at its limit.

    • It’s quite possible that there are different pins/connector sets for different current draws. This cable might be using the wrong connector with the same physical size but lower current rating. The fact that the cable has been soldered to skinnier wires in the actual connector suggests this, but it’s quite possible that the connector is the right one.

    Consider yourself corrected then. I’ve skimmed your comment history. Your go-to insult is “bootlicker” or alternatively, a simple clown emoji. In your comments you seem to provide very little context as to why you think that, it’s just, “I deem you to be a BOOTLICKER! Next!”

    So maybe a little guidance for you:

    The very, very, first thing you do when dealing with perceived propaganda - be it on mainstream media, online, or wherever - is to remove all the emotion and insults and see what’s left. You know what I see when I parse your comments like that? Very little.

    Thus I conclude you have nothing of importance to say, and you become background noise that gets tuned out.

    Actually your comments do have some small value. I check your bootlicker-comment-score and if it’s greater than 5, I know the community you posted in isn’t worth my time.









  • And holy shit does their algorithm latch onto any minor interest in their content.

    Accidentally tapped on a floor tiling video the other day, three days of tiling and handyman videos jammed into my feed and me pressing the “not interested” button on every single one.

    Facebook, I am there for the rare post from my 150 or so friends and family. That’s it. Nothing else.

    The reason we don’t use it anymore is because actual posts from real humans we know are buried under a torrent of shit. Sometimes their posts take days to surface leading to all sorts of chain-mail posts on how to “get your feed back”. None of which work because the whole business model is about jamming sponsored shit down your throat.
