Swift 3 SF314-54-55JD RAM

Is the RAM for Swift 3 SF314-54-55JD upgradable? If yes, what RAM model/module can be fit on it? Thank You.

Upgradeable to 12GB max with the addition of an 8GB DDR4 laptop module. Jack E/NJ

When in doubt, resort to YouTube, it's a pretty good resource for these sorts of questions. This vid would be the relevant one for you:

Also, as for the RAM amount you can use, you'd need to check 2 things:

• The kind of RAM you're running, which could be seen in HWiNFO for example (a free info and diag program):
  
  
  
  You'll be looking for the memory type, speed and module type. For the system in the screenshot for example if I were to replace the RAM I'd need to look for a stick of DDR4-2666 SO-DIMM.
  
  
• Aaaaaand the max amount the processor can actually deal with, in the same program you can see which one is yours, in this case it's an i7-10510U, so off to the manufacturer page you go:
  
  
  
  So it supports 64 GB max and the types can be either DDR4-2666 or LPDDR3-2133. If this were the system for example, don't you go buying LPDDR3 RAM since it has DDR4 already (their pinouts are different and they're not interchangeable, Acer chose DDR4 for this model for example).

And that's about it, in your case at least from what I could see in the video there's 1 slot (like mine) so even if the processor could run in dual channel unless there's some RAM already soldered into the motherboard you'll be running single channel only.

As to whether you could put all of the memory the processor supports in one single slot (e.g. a DDR4-2666 SO-DIMM of 64GB for me if that even existed) or not, I wouldn't know. Never tried it myself, half of it for sure (I could probably put a 32GB module in there).

Aaaaaaaand regarding memory clock speed, that 2666 you see there, you could go higher and lower. The memory controller would choose the appropriate one, for example I were to find a cheaper DDR4-3200 module instead of the 2666 plugging it in should be no problem, each memory stick has a set of speeds at which it can run and it's all automatic (even XMP most of the times).

See the one I have installed for example:



This stick could be plugged into a machine that only supported up to say DDR4-2133 and work perfectly at that speed. If I ended up buying something that maxed out at DDR4-2133 for example I'd be missing out on the benefit of having faster RAM, but it'd work just the same.

I hope this has answered your question and doubts
