QNAP x53D 16GB and 32GB Crucial Memory Upgrade Guide

How to Upgrade the RAM in your QNAP TS-x53D NAS to 16GB or 32GB

Back in early 2020 when the QNAP TS-x53D NAS was first announced, many users were surprised at the maximum memory limit that the manufacturers stated on the specifications. With the Intel J4000 series chip that QNAP TS-x53D NAS arrives with, it did seem odd that the maximum or 8GB of DDR4 2400 memory for this chip was listed firmly in the specification. On the face of it, 8GB seems like plenty. That will comfortably support the NAS tasks of a plex media server, all those productive first-party NAS applications and backups. However, as file sizes grow, as NAS surveillance gets popular, as virtual machine and container station applications grow in popularity, it will not be too long before you will see that memory use ALWAYS above 80% in the task manager. Sadly, we have asked the manufacturers and they continue to stand by the fact that you cannot exceed this limit, officially- understandable, as stability of your system is ESSENTIAL. However, I am pleased to tell you that I have been experimenting with several different sizes of RAM sticks and various brands, and am pleased to confirm that not only can you use non-official own-brand memory in the QNAP TS-x53D NAS (so that is the QNAP TS-253D, TS-453D and TS-653D), but also that you can install two 16GB sticks of DDR4 RAM (one per slot) meaning you can have a QNAP TS-x53D NAS with 32GB of Memory! Read below for my guide, it will detail how to install the RAM, how to check that it is installed correctly and how to test that it is working straight away.

Upgrading your QNAP TS-x53D NAS to 16/32GB of Memory – Pay Attention

Before we continue with the guide, it is worth highlighting that the QNAP TS-x53D NAS manufacturer strongly recommends that you do not exceed the stated memory limit on their specifications page. They also highlight that using non-official memory in your QNAP TS-x53D NAS may invalidate your warranty. We at NASCompares cannot be held accountable for how you use this guide. However below I will show you where to buy the individual memory and QNAP TS-x53D NAS NAS device you will need. Only attempt this upgrade if you are comfortable with the terms laid out above by the manufacturer. Alternatively, you can buy the QNAP TS-x53D NAS with 16GB or 32GB pre-installed from the NAS experts, ensuring your warranty is unchanged.16GB QNAP TS-x53D NAS Memory Upgrade – Step 1, Physical Installation

What you will need:

  • A QNAP TS-x53D NAS – 




  • 2x Crucial 16GB (32GB Total) Memory Upgrade – Link below

VERY IMPORTANT – The Links used in the article below towards the correct unofficial memory are occasionally changed (beyond my control) as it will direct you to the site in your own region/country. MAKE SURE to check that the memory module (especially 16 and 32GB SODIMM modules) are DUAL RANK or ‘DR‘, as Synology NAS typically have trouble with SR/SINGLE RANK modules.

  • Small Phillips Head Screwdriver – (kinda optional but recommended for chassis

  • (OPTIONAL) Antistatic gloves and Envelope – useful to eliminate static charges and also to store the removed older official memory sticks)

First, we need to ensure the QNAP TS-x53D NAS is completely powered down/off and the mains power has been disconnected. It is recommended that you remove the Hard Drive or SSD that you have installed before accessing the RAM as it may block the slots. Additionally, you should remove the hard drive media as the unit will be moved around a lot during the memory installation and this could damage the drives. Be sure to keep a note of the drives that you remove and the order they were installed (HDD Bay 1, HDD Bay 2, etc) as installing the drives in the wrong slots could damage any existing RAID you have set up internally. Next, we need to access and remove the existing memory, as the new 16GB / 32GB of memory upgrade for our QNAP TS-x53D NAS will occupy both slots. Be sure you eject the official memory sticks using the clips either side of the slot, as well as only holding the memory sticks by the narrow side edges, never touching the chips or board of the money or NAS

Once you have removed them, they can either be stored away for a later project, installed in a compatible laptop or sold on eBay etc to make a little cash back! Once they are clear, install an 8GB or 16GB DDR4 Crucial Memory stick in each of the now available slots, making sure that you click them both in with the clips either side. Once down, replace the QNAP TS-x53D NAS chassis lid if you removed it for ease of access, as well as the hard drives. You have now concluded the physical installation of 16GB / 32GB of Crucial DDR4 memory in the QNAP TS-x53D NAS.

16GB / 32GB QNAP TS-x53D NAS Memory Upgrade – Step 2, Checking the 16GB Memory is Recognized

What you will need:

  • The QNAP TS-x53D NAS NAS – Obviously
  • DDR4 2400 or 2666mhz SODIMM (non ECC) Memory
  • A web browser (Chrome, Safari, Firefox, etc) on a Windows, Mac or Android Machine) accessing the QNAP TS-x53D NAS user-interface as you normally would.

Next you need to power up your QNAP TS-x53D NAS NAS and access it as you normally would. If you are buying this NAS first time and have yet to set it up, there are numerous first time set up guides and tips on the SPANTV YouTube channel here – that will get you from the hardware installation to set up the QNAP TS-x53D NAS NAS for use. Once the NAS user interface (UI) is ready to go, head over to the hardware specification page shown here:

As you can see from this CPU and Memory display, the QNAP TS-x53D NAS has recognized and made available the 16GB of crucial memory. It will be immediately available for use and you will see that the % amount of use of the RAM in the resource monitor will be much, much lower, as there is significantly more memory available for the system!

16GB QNAP TS-x53D NAS Memory Upgrade – Step 3, Checking the 16GB Memory is Working

There are several ways to check the memory is working on your QNAP TS-x53D NAS correctly. First, you can perform as many actions and processes as possible (scans, copy/pastes, thumbnail generation, transcode a 4K file, RAID changes, synchronisation, etc) at once to see how the task manager and resource monitor behaves in the QNAP TS-x53D NAS. It should spike each time and at a greater height as you do more and more and once it exceeds the memory you had previously installed, this is a good confirmation that the installation is working fine.

Alternatively, you can temporarily allocate chunks of memory and then that is a much more reliable test. Install the virtual machine application for the QNAP TS-x53D NAS (P.S. for Synology users it is the Virtual Machine Manager and for QNAP it is the Virtualisation station). Then you can create individual VMs (it is alot easier than it sounds and the QNAP TS-x53D NAS VM software is very user-friendly) then allocate 3-4GB of memory to each one. When you have created 3 or 4 individual virtual machine containers on the QNAP TS-x53D NAS software, then you can run them all at once and that will immediately use almost all the memory at once!

If there are any issues with the memory, it will show here almost immediately. If no problems, then you know the QNAP TS-x53D NAS 16GB or 32GB of DDR4 crucial memory installation as successful. You can then delete the VMs in the virtual machine software and then free up all that memory again.

    1. Could you please advise if Kingston HyperX Impact DDR4 16GB x2 (HX426S15IB2/16) will work or not?

    2. Intel, not QNAP, says that the CPUs in this series will not function properly with more than 8GB of memory. QNAP is simply passing on this information to customers. I suggest that the reason you are able to successfully install the elevated memory is a failure on the part of QNAP to block its recognition.

    3. Intel specs say the J4125 (in TS-453D) supports max 8GB RAM.(its not just QNAP, I would understand if they go lower than Intel, but they obviously don’t).
      Is intel lying in this case? Or is it by luck whether it is supported by the CPU and just the guaranteed max is 8GB?
      How would you explain this discrepancy of 8GB in the CPU spec vs 32 as per your upgrade guide.


    4. Thank you!! Worked for me! I ended up taking my TS-453D from 4GB to to 32GB with https://amzn.to/2LulQNo . Thank you for reassuring me that it would work and for the tip about the importance of Dual Rank (DR).

    5. Very interesting, indeed! Would you be so kind to check if it can be done with Asustor’s Lockerstor 4 and Nimbustor 4, please? They use the same CPU but maybe there’s more than that to it. Thanks a lot!

    6. I’m the bearer of bad news unfortunately…

      My TS-453D won’t boot with new Crucial CT16G4SFD8266 (or CT2K16G4SFD8266 if you purchase them in combo) – I have tried 4 different modules separately, none will work. So that removes pretty much the possibility of having a bad module.

      Firmware is Build 20210107

      BIOS Version is Q04MAR12

      Putting back the original OEM 4GB module makes the TS-453D boot again correctly.

    7. I am curious if it’s the crucial brand or if Qnap blocked the upgrade. Has any one tried a differnt brand of ram other than the crucial?

    8. TS-453D with Firmware Build 20210107 & BIOS Version is Q04MAR12

      There seems so little stock around at the moment (especially reasonably priced near rrp) so I thought I’d risk Crucial Ballistix from Amazon:
      Crucial Ballistix BL2K8G32C16S4B (2 x 8gb)
      https://www.amazon.co.uk/Crucial-Ballistix-BL2K8G32C16S4B-Laptop-Gaming/dp/B083VWCZLQ – in stock with Prime for £65

      Plugged in and worked off the bat – booted fine and 24hrs later no problems (so far).

      Yes, I know this is “gaming” ram and the 453D isn’t going to use the 3200MHz speed, but slower speeds were out of stock and more expensive!?! As far as I could spot, this was one of the cheapest branded 2 x 8gb kit available in UK atm.

      As it seems the majority of people with problems seem to be trying to run 2 x 16gb sticks, could it be an 8gb limit on each slot issue?

      As for other brands – I think I’ve seen a few on the Qnap forum using HyperX and GSkill Ripjaw, but you’ll have to check which sets.

      1. I agree about the 2x8G. I tried several brands of 2x16G with no boot up. I backed of to 2x8G and it boots no problem. As for how others are getting 32G I have no idea. IMO I think 16G will suit my needs for now. I will keep an eye here in case I need to upgrade in the future.

    9. I also was not able to get 32GB total to work. The NAS just would not boot up. Running on 16GB just fine. FYI I bought Crucial .

    10. Dear Rob, thank you for this great article. I have just one question: This is clearly about the x53D and which RAM is compatible. But in the list of RAM the reference is the NAS DS920. Is this a mistake or is it something I am not getting.

    11. I can confirm that TS-453D (BIOS: Q04MAR12, Firmware: works with 24GB RAM (1x Crucial CT16G4SFRA266 + 1x Crucial CT8G4SFRA266). Prior to that I was running 2x CT8G4SFRA266 for about four months without any issue at all.
