Memory Upgrade

Dear Community!

I would like to ask, if it's to possible to upgrade non-whitelisted RAMs? I've got my hands on a stock Samsung 4GB module, but i feel it's bottlenecking my system, and suffering a lot with stutters, major fps drops, google chrome crashing and no way to multitask like this.
As my best knowledge, this laptop has 2 SO-DIMM slots and I can upgrade the capacity up to 32GB (checked in lenovo diagnostics). I found these modules, and I would like to ask your opinions about it. (I'm not sure if this forum shows my specs or I do have mention it separately, but I can attach my specs if it's required)

These are the modules that I'm thinking about to get:

OR

https://www.aqua.hu/8gb-2400mhz-ddr4-notebook-ram-crucial-cl17-ct8g4sfd824a-546232.html

I know, that the first one is Single Ranked, and the second one is Dual Ranked. Both modules are CL17, 1.2V, unbuffered non-ECC, 2400MHz, 260pin. My plan is to get 2 "same" (so 2*8GB=16GB) from one of the links above, as I could find no kits for this laptop.

 

Questions are:

  1. Could they work?
  2. If so, should I consider choosing Single or Dual Ranked?
  3. Will I void my warranty, if I remove the iron plate covering RAMs?

Thank you for your time, feel free to share your thoughts. Sorry for any misinformations shared or typo, I'd gladly ask you to guide or correct me.

Re: Memory Upgrade

Go for it, as for warranty....If you dont break anything they cant know if you opened the laptop since theres no warranty sticker anywhere.
As for the RAM, you can go even lower latency, frequency must be 2400mhz(any higher will make it work at 2400mhz) and ddr4, thats it.

Thank you for replying!

Couldn't find module with lower latency at this price range and this is optimal for me. Is 17 too high?

Re: Memory Upgrade

Its alright, not much difference between them, only if you compare cas 17 to cas 9 there is an increase in performance. But is 10%

Glad to know that!

What about Single or Dual Ranked DIMMs? I've seen a picture explaining it, but can you feel the difference?

Re: Memory Upgrade

of course its better, you can even get quad, performance increase is 20 to 30 %
if you see this on the sticker 1Rx4 its single, if you see 2Rx4 is dual.
