What problems can arise when resoldering DDR3 memory?

Question

Electronics

Good afternoon,
Please tell me what problems can there be when replacing a soldered memory on a laptop with another one?
The new memory will correspond to the old one in terms of voltage, power, frequency, possibly the manufacturer (or does it make sense to be tied to the manufacturer?), but with a larger capacity.
Basically, it is not so much the question of the soldering itself that is of interest, as the subsequent picking up of this memory by the BIOS and all the rest of the hardware.
Links to the results of such a replacement in any language are very welcome.
I would be grateful for tips and opinions.

Answer 1

Info about banks is recorded in SMD - ROM, it should be somewhere near the banks.
If you solder twice as many memory chips, then the pisyuk will still repeat that nothing has changed.

Answer 2

A dangerous undertaking, there is also a strapping around these modules, what if it does not fit. Plus, it is not known what is happening with the controller and soldering is also difficult. On the net, I could not find any mention of such manipulations.

Answer 3

Well, at least the lack of equipment will make such delicate soldering a living hell. In general, it is very difficult and if the hands tremble even a little, it will only get worse. Super thin stings and tricks with needles will not save here, but nothing will save. Unless the device is special. What can happen? Nothing, in the worst case - you will burn something, although most likely you will just make a brick. But the BIOS with memory works a little differently, so the trick should work.
From what I found .

Answer 4

Yab took the memory of the same manufacturer, etc. In general, so that all the parameters match, but the volume is larger. And it's probably worth replacing all the memory chips so that there is no conflict.
You can try, if you don’t screw up when soldering, you can always return the old chips.
