The thing here is, even if you were able to successfully install new RAM chips onto the Apple Silicon SOCs, I’m pretty sure the RAM config (similar to SPD data on x86) is actually a fused value in the SOC and cannot be changed... Therefore completely preventing the upgrade in that regard. Also, the other issue here is the chips themselves are a completely custom Apple design, and cannot be sourced anywhere.
they possibly can be sourced from donor board... problem is still apple's clever design to make it impossible or not feasibly/worth the upgrade due to the risks associated with either laser etching off or cncing the chips! both still very risksy and also labor and chip prices added will make this only a hobby or bragging rights project rather than a customer work i think.
hey bro :) there is no resistors or anything to upgrade it. say you where to cnc off the ram clean , then take a 16 gig . 2x8 add all the power delivery to it and pit new ram, still won't work??
@@mytester6208 we have tried replacing/upgrading m1 ram ics but dosdude1 is right. spd/ram config seem to be production fused and cannot be changed. in other words -- you can replace faulty ram ics with working identical ones from donor, but you can't replace them with higher capacity ics.
great video! I lmao when I saw that the only way to u;grade M1 RAM is with laser destroying layer-by-layer the RAM chips :D :D oh, apple, you really could of had it all until your greed overpowered inside
Hello iBoff! Quick question about the 2017 A1534 12inch Macbooks. Is there any difference between the motherboards of the 16gb models and the 8gb models? I tried to find any information about any possible chance of a ram upgrade for this model and I can't find any. Not even the schematics show a possible 16gb resistor configuration, but then how do they have 16gb model? Me and I believe many others would love to know if this upgrade is possible. With love from a wannabe teenage repairman :))
18:30 the glue used on the ram ic's is the same as the glue used for the die bonding, 450c/500c won't be enough to soften it , it would be safer to use a cnc with a verry fine tip to gring off the ic's
I also tried, for the sake of science to remove the RAM of an M1. I gave up after scraping the glue: given the amount of heat needed just for that, I knew it wouldn't be possible to remove the RAM. I believe a safe way would be to drill out the RAM with a CNC machine (not that expensive). It's the same idea as that laser you showed.
There are cnc machines that removes cpu from iphone, so if you make it to remove till the solder balls then clean the glue and solder balls by yourself. Then find the new ram ic and solder them with 150c or 138c. Could work
maybe you can try again but this time, cover the M1 wafer with kapton heat resistant tape and since apple uses Lead free solder, its removal temperature is much higher so you should increase heat gun temperature
I thought the memory was directly on the wafer, but it's on separate chips. Apple chose to limit its upgradability. So even the high-end Apple Silicon MacPro's RAM can't be upgraded.
@@ibrahimMorteza no, this is standard POP package on package like $30 raspberrypis. HMB has 10x the ball density. Apple totally did it to control second hand upgrades market.
@@rasz I am the biggest Apple fanboy, but this combined with soldered SSD is a bit rapacious and abusive. Considering the ever increasing memory footprint of OS updates and the limited lifespan of the NAND storage, they've designed their machines to fail. This is one of the many reasons why the 2013-2015 models are a better value. They're slower, but not significantly slower for most tasks.
@@bobweiram6321 they have been going this path since acquiring the custom chip company and arm licenses. it was inevitable to control their profit margins by going custom. also hackintosh community was a big threat so they did what they (one of the greediest and most control freak company) do best! make custom chips, make it in a way so impossible/feasible to repair upgrade or replicate! with m chips, they did all three! never been a fan of them from the getgo, not sure why people still surrender to their will and support their business and business model!
Amazing as always.. maybe theoretically a better way to upgrade the RAM on M1 is by removing the M1 SoC off the board to the side and then do the RAM upgrade?
@@mechamicro thats the purpose of this design, dont think it is an afterthought or by chance! they make it near impossible or feasible to repair-upgrade-replicate... 1 ring to rule them all. now tying all of them together under a common db of components and seal it, so only apple approved replacement parts can be done, it s full circle of control of entire money!
The SSD doesnt have Special Firmware. the Management Chip for the SSD chips is inside the M SoCs. Apple Basically cut out the SSD Controller Chip u usaly find on NVMe SSDs and directly integrated them into the SoC. so they need to be aranged in specific way so they match the Controller.
@@bennaambo2716 What about the video about SSD's from IBoff? He mentions that the SSD has special code which needs to be present to work. Also there are 2 versions of the T2, one of which only supports upto 512GB if memory serves.
Apple is the worst company. They corrupt their designers to ensure repairability and upgrading is impossible. I'd like to see Tim Cook and his friends get theirs.
You need to do a compute benchmark otherwise you cant tell if the GPU is faulty or not. It seems to work fine until the OS makes a compute request. The faulty GPU will work fine forever if compute is not requested at all but if its faulty, the computer will crash when compute is requested. This is totally irrelevant to CPU operations or 2D GFX.
