RTX 2080 Ti Memory Upgrade to 22 GB

In practice, it's more like a 75-90% failure rate if you're unfamiliar with ball-soldering techniques, which most are since it's been considered impractical to do soldering in the US since the through-hole days, and so there's not a professional tradesman class to teach kids. What does exist of soldering is stuck in the far past from an electronics manufacturing perspective.

This can be a result of unexpected and costly if not worse, surprises.

Not to mention that the bar of acceptibility is moving. We had RAM in slots in laptops for a long while, but it's (not so) slowly going away. You can still find laptops with SO-DIMMs, but it's not a given anymore.

512 conductors that have to be exactly the same length. Make them longer you'll say- now you just lost your high memory clocks to propigation delay and parasitics.

Seeing the problem?

A modern cellphones have only about 10 replaceable assemblies[1] - repairers aren't typically replacing individual broken chips, an entire assembly/part. "[knowing] what you're looking for" is easy of you know what broke the device, or following basic troubleshooting steps.

Getting into repairs these days is easy; YouTube, Alibaba, Forums/File-sharing sites, USB-C and Open Source firmware-flashing tools have conspired to lower the bar of entry. If you have an old phone in your device drawer with a damaged screen or unusable battery, you probably can fix it yourself, with the right tools and some patience.

1. Cover, chassis, screen, digitizer, mainboard, speaker, mic, daughter-boards, variously cables/ribbons

Or from a previous customer who had to replace a whole power supply module, and those parts happened to be perfectly fine on the otherwise broken subassembly they left behind for disposal.

That's how repair efficiency enabled by scale looks like when you zoom in. They'll replace your broken screen in 5 minutes and for 10x less than the price of the replacement screen (!), as long as you let them take the damaged one, because someone will actually fix that damaged part and use it as replacement for the next customer, etc. There is enough volume they can decouple and time-shift actual repair and replacement.

(And of course should they not have a freshly repaired part of a kind, there's probably a booth selling those very parts within 50 meters of where they sit, that's also a direct line to some factory in Shenzhen. You know, the kind of booth where they look at you funny if your answer to "how many pieces" has less than three zeros in it.)

so I did a search for anyone doing microsolder repairs nearby, picked the closest, and found someone who diagnosed, quoted, and then replaced both ports, and a chip that had vaporised itself along the way, for a couple hundred AUD.

But why not offer that? All else being equal I'd rather fix something than put it in landfill and buy a new one. Am I the only one?

The only thing I can imagine is that there is an underground repair business buying broken items to repair them and resell them that was efficient enough to keep the margin between non-working and working that low.

You may be thinking of "memory manager" utilities like QEMM and EMM386 which tried to maximize the amount of conventional memory available to programs (i.e. below the 640KB boundary). These programs worked primarily by causing drivers and TSRs to run in upper memory - they didn't actually provide more memory.
