Upgrading RAM on N50-600-EB16. Which RAM is supported? / Motherboard RAM Speed Throttling?

Hi all,

I am planning on adding additional RAM to my N50-600-EB16 and I am wondering, what RAM is supported by the motherboard and if there are any obstacles to creating a Duel channel RAM set up? 

I currently have a single 8GB DDR4 strip of RAM.  I am considering adding another 8GB of RAM of the same kind already present, or purchasing two 8GB strips of identical RAM to completely replace what is currently in the machine.

I have seen a video on YouTube where an issue was raised regarding RAM speed throttling in Acer N50-600 computers, and something to do with JEDEC verifications playing a role in how the motherboard of the N50-600-EB14 identifies RAM.  Is the motherboard the same in the N50-600 EB16?  Am I likely to run into speed throttling or other issues, if I purchase faster RAM?  In the video I saw it is mentioned that the BIOS options for N50 computers are quite limited due to locking, is this the case?  If so, is there any method for unlocking options or otherwise safely over coming any RAM speed throttling?

Am I best to seek another stick of identical RAM with the same speed as what is already installed?

Apologies for the barrage of questions, but I want to be certain that I install the correct RAM and avoid causing any damage or accidently worsening the performance of my PC.  Thanks for your help

    MB has nothing to do with the RAM speed as the memory controller is build in the CPU! So first let us know what is your CPU and current ram model and speed with CPU-Z.

    So if your model has this CPU - Intel® Core™ i5-9400F Processor, then look here:  https://ark.intel.com/content/www/us/en/ark/products/190883/intel-core-i5-9400f-processor-9m-cache-up-to-4-10-ghz.html
    it supports up to 2666MHz so as stated look what you already have and get the same.

    I am concerned regarding what I am hearing on this YouTube video.  The speaker is saying that the motherboard is reading JEDEC to determine clock speeds for the RAM.  He seems to be cautioning the viewer that its actually really hard to find and match the same type of RAM, because manufacturers do not generally list the JEDEC information.

    I don't know if Youtube links are allowed here so I wont add the hyperlink unless that's okay.  The title of the video was "Upgrading this Pre-built is way harder than it should be" Time stamp 3:55.

    Kingston list them in their datasheets for example, provide screenshot of the memory tab and SPD tab of the CPU-Z. Youtube links are allowed. Trust the random youtube guy who doesn't know what he is talking about (Base Frequency: PC4-17000 (2133MHz), Tested Frequency: PC4-21300 (2666MHz)) -  your choice. MB is reading JEDEC profiles -LOL

    I wouldn't say that I trust him, but his comments were cause for me to be cautious and concerned.  I hope my caution hasn't come across as insulting.

    I am a layman about this stuff, and he cited a post written by JordanB from this community who appeared to have two stars and was rated as a Pathfinder, (whatever that means). 

    I appreciate your efforts to clarify for me. 

    I understand the CPU-Z will be helpful.  I am not familiar with this program so I want to be careful before running it and check its reputability.

    Should I be concerned about the 1333 MHz listed next to Memory Frequency ?  That seems considerably lower than 2666MHz (precisely half, actually).

    Also is ACER capable of supplying customers with additional Memory of the same type for upgrading purposes?
  • batmalin
    batmalin Member Posts: 4,231 Guru
    DDR means Double Data Rate hence if you doube the 1333 you will get the real speed. Acer can sell you same RAM but you will not like the price. I still don`t see the screenshots requested

    Hi Batmalin,

    Thanks very much for identifying the correct RAM for me and even going so far as to locate a convenient source for purchase, you have helped me so much.  It truly was altruistic of you.

    You mentioned that I could purchase 1,2, or 3 more RAM sticks.  Does my computer support duel channel memory?  If I add 2 or 3 more will my computer operate in triple or quad channel?   Should I expect much in the way of noticeable performance improvements for adding more than 1 more RAM stick?  Could adding more RAM beyond an additional 1 more stick lead to lower performance?

    The  main performance increase will come from the amount not from the dual channel, best case scenario is to have overall 2 or 4 sticks of RAM.

    So, as an update, I have the new 8GB RAM stick, and I am prepared to install it. 
    I would like to know, if it is best to place the RAM into the slot immediately next to the current stick, or should I space it out one slot or more across the 3 possible open placements?


    I notice in this example image I found of another N50 that the RAM sticks are spaced out.  Is there a reason for this spacing?  

    Currently my system has one 8 GB stick in the slot closest to the Yellow Arrow ( the front of the machine and the CD Tray).
  • batmalin
    batmalin Member Posts: 4,231 Guru
    Yes, in order to have a dual channel you have to use slot 1 and slot 3 or 2 and 4. Put it like on the picture.
