Can soldered RAM be Unsoldered?
If removing/upgrading the soldered ram is as easy as melting down a solder joint or two, then that’s a very easy obstacle to overcome. Or is it something where if you were to do this, it would mess up the mobo? Well, you can unsolder the RAM, but Apple won’t fix the damage that you _will_ cause under warranty.
Can soldered RAM run in dual channel?
Having two different RAM formats, one soldered one in a memory slot, this RAM can not run as dual channel. You have to have 2 ram modules of the same speed AND the same size for it to run as dual channel.
Is RAM soldered to motherboard?

Why do laptop manufacturers solder RAM?
The room gained by using soldered memory helps keep the laptop slim and can be put toward other purposes, like cooling or a bigger battery. These benefits likely take precedence for manufacturers compared to enabling user-serviceable RAM. Thus, you’re more likely to find user-replaceable memory in these machines.
Can a ram stick be soldered on a motherboard?
Unless you are a real expert you can’t. First it’s likely not a “ram stick”. It’s likely a collection of memory chips surface mounted on motherboard. Unless you have an SMD reworks station, a steady hand and experience with surface mount soldering you can’t get the chips off without destroying everything.
Why are the RAM slots parallel to the motherboard?
Because the form factor of a laptop precludes the desktop orientation where the memory is perpendicular to the motherboard, the RAM slides into slots that allow it to be parallel to the motherboard once installed.
Can a 4GB RAM stick be upgraded to 8GB?
You can upgrade your 4GB stick to 8GB, but it will most likely lose dual-channel compatibility since it typically requires both channels to be the same size. Lenovo has one model with a max of 16GB, but that’s without a soldered RAM module. Since you have 4GB already soldered on, the max you can add is 8GB.
What do you need to know about RAM slot order?
Make sure the RAM you install is the same (same type, same capacity, same chip) across the pairs, or in the case of a triple channel motherboard, across all three slots. Modern motherboards all come with a feature called “Interleaving” which will bring down the performance of all RAM to the slowest RAM on the board.
