Learn how to upgrade soldered RAM of MacBook Air (13-inch, 2012-2017) from 4GB to 8GB. Online courses at masterliu.online. Model: A1466 Motherboard: 820-00165-A
I understand everything until the resistor changing part, why do you need to change resistors are they changed on the board that has the original 8gb ram?
each RAM chip module requires a specific resistor value to function as pull up resistor. This varies according to manufacturer and chip model, type, etc. In this case however, the RAM chip wouldn't be properly connected without the resistors as they would be an open circuit
@@musken ok. so how does an actuall expansion RAM slot work then? Does the motherboard have internal ajustable pull up resistors which gets adjustet to the RAM module? 2nd i think the correct resisitor value corresponds to the Value of Voltage used for the RAM module. So the replacment module propably has a different voltage value than the orginal? Sorry that im confesed but for me than looks like the board is intelligent enough to adjust the voltage to the ram module but not the pull up resistor vaule, which in my mind makes not a lot of sence... im planing to work on a ram upgrade myself, so i could clarify that, that would be awesome...
What do you think if you install 16GB of RAM in the MacBook air 2013 and put strap-on resistors according to the MacBook 2015, will it work? The i5 4250U processor supports 16GB according to the Intel website
not about the cpu, it's about the bios that needs to know the memory type. If you don't know how to tell the bios your new memory chips, it's hopeless. And unlike DIMMs, the bios has pre-configured chips that are allowed.
An idea for you: take a cheap Android tv and upgrade ram. Most (all) Android TVs with chromecast buitin are very limited on what they do because of 1.5-2gb ram. Wish I had the skills.
Very nicely done. Thanks to you I can confidently say I will not be upgrading my ram. I have the tools, but I'd be very lost if something went wrong.
Thanks sir
Its very helpful. You doing a valuable work 🙏
Great content, please keep it coming
Thank you sir!!!! Very clear instructions! All the best to you from Buenos Aires, Argentina.
Hi master, how are you.. how can I contact you?
Is it possible to do 16GB?
This seems imposible to me. Very good Job, Master Liu
can you share the file for transfering resistor
hı Could you share the word file about transferring resistors
Great job. Please sir how do I purchase these ram chips / or can I unsolder ram chips from another mother board
did the new memory modules already have the solder applied on them? That's normally the F'd-up part.
where are you from? I really like your work for upgrade. Thanks a lot😊
Master Liu, it will be possible to share the document with the replacement information
They are on the schematic

Great video, can you please share the word list for resistor replacement
Liu, please, could you tell me, what resistors I should replace on my mac mini 2014(model A1347). I wanna replace 4g to 8gb memory, thanks a lot.
Find boardview for both of them, you can google. And, compare ;). Once you'll notice a difference, you'll know which ones you need to change :).
anyway to solder more ram onto surface go surface go2?

有料，請問多少錢升級
Can u make how to soldering more cpu cores m8
Please can you post your Word document
All the MacBook ram upgrade ?
The r1636 resístance is 100 k ?
Holly... without ir table...never try to repeat it)
How can I contact you master .....
I want to buy 100 of these ram. do you sell?
Can you upgrade it to 16gb of ram?

我想買 100 個這樣的 ram。 你們有賣____嗎
Hi master liu can you send the file word you used at my email?
32GB for MB air!
Great video tho looks hard :o
