I have watched more than a few videos where someone tries to upgrade soldered RAM at home, only ending up sending the laptop to the same repair shop they hoped to skip after a failed experiment. Unless you can put money on your words and provide some sort of guarantee, nobody is going to take that.

The point is you can do it yourself , you don't need anyone else's guarantee.

If the untrained "you"'s failure rate is above about 25% with the failure result being a merely inoperable but repairable card, it's not an acceptable outcome for most people, who quite reasonably see it as an unacceptable risk.

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.

Tl;dr: https://xkcd.com/2501/

The average techie is a coward.

My 2008 MBP had a motherboard failure due to bad factory solder, but you could sometimes fix it by taking the motherboard out and putting it in the oven for just the right amount of time to reflow it. I still remember how scary it was putting the logic board in the oven - but it wasn't really bravery, when the alternative was a non-functional laptop anyway. I did eventually give up on it after it had relapsed two or…

My MBP had the same issue and was eligible for a replacement but since the computer couldn’t boot due to a GPU issue they couldn’t run the GPU test to verify it was a GPU issue. Even though you could clearly read the logs and tell it was the GPU.

The RAM in your desktop could run at much higher frequencies if it were soldered. The RAM the M5 Macbooks use runs at 9600 mbps. The base spec for DDR5 is 4800, and I rarely see people running at much higher than 6000. There's probably someone who's gotten a 9600 mbps overclock running on their desktop, but it's unatainable for a normal consumer outside of machines with soldered RAM.

This doesn't explain why non-soldered RAM isn't okay for graphics cards when it is still considered perfectly acceptable for desktop computers.

Because you can't sell more graphics cards if consumers get more use out of them.

At least in Australia, anything outside common phone repairs goes in to the "not worth it" basket. I had a USB-C port snap of a microphone, PCB pads were still fine, just needs someone to use a hot air gun to attach a new port. Repair stores didn't want to touch it. And I can see the logic. Wages are so high that anything that they can't exactly know the repair time and success rate can easily exceed the device value…

I don't entirely understand why they "didn't want to touch it"? Surely they were capable of soldering a new port. I'm sure they'd have had to charge a lot. There's unlikely to be much difference in cost between the repair and a replacement microphone. 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?

> I don't entirely understand why they "didn't want to touch it"?

Customer: it’s just this specific solder job

“They”: that’s what you say, but there might be other issues, and we cannot tell without spending lots of time checking things

Customer: no, it’s just a solder job.

“They”: OK, we’ll solder that, but the risk is on you, and you’ll pay regardless of the outcome.

Some time later:

“They”: operation succeeded, patient still dead.

What do you think happens next?

A: customer thanks “them” for their effort, pays and leaves

B: customer starts bickering that “they” destroyed their phone, leaves negative reviews online, etc.

I expect a significant percentage for option B. Even if that’s rare, it requires only a few negative reviews to not be worth it.

I can see people wanting to avoid that, even if it effectively leaves money on the table.

So good, did this 3 times, everytime it would fail faster haha. Another trick was to run a benchmark, disable sleep and wrap it in some blankets until for an hour or so until the gpu solder was reflowed, didnt try that haha

No, he's right. Techies are cowards. Those poor but educated people in the slums of Shenzhen are reverse engineering Nvidia GPUs to find out how to add more RAM, so what the fuck are we doing to have less results?

…well put, and their tools are basically beetlenut and long finger nails

HN crowd is treating this as some sort of sorcery. Meanwhile it's just everyday business in China. People send their laptops or graphic cards with soldered RAM and get the device back with double RAM/vRAM.

HN crowd is treating this as some sort of sorcery, you can do it at home with a $60 hot air station. The only thing approaching "secret sauce" is the BIOS modding, which varies in difficulty depending on the device. For many devices it's just a case of reconfiguring strap resistors.

this bios modding, you just get a boar supported by coreboot or something similar if you want to make it easier. if you like to tinker its an option to avoid certain things. uefi firmware can be pain to extract and unpack i think and often its signed. u need to modify the firmware because anything after is already loaded into ram and from there u can not reinitialize ram controller

A longer time ago, sound cards used to have expandable RAM too. Go back far enough (486) and cache was off-chip on simms too!

Yep. Soldered is just the best manufacturing process (besides on-package). Moving things close together simply delivers better outcomes and that will always trump openness concerns.

I would imagine that something like LPCAMM2 for GDDR is entirely possible and will never, ever be seen because people already accept replacing an entire $10000 GPU to get another 32GB VRAM on the next generation, so why give up that guaranteed revenue stream?

You can definitely do it by yourself(after all, the tech worker is just a person like us). But it will definitely cost more than $60.

Hot air station, stencil, stencil frame. preheater, etc. Even board view sometime need to be purchased.
