Upgrading memory on the QNAP TS-873

Since May of 2019, I’ve been toying and using the QNAP TS-873 at home. I haven’t pushed its limits due to my heavy work schedule and after work projects but I’m starting to play with it more and more as of recent.

When I purchased the TS-873, I opted to go with the lower spec memory configuration of 4GB DDR4, knowing that I would eventually get the upgrade bug.

I looked at the utilization of the CPU and memory in default configurations and although it was not terrible, the memory utilization could sit at medium-high depending on what was being performed on the NAS.

At first I wanted to eventually max out the 64GB memory configuration on this QNAP. I wanted to buy 2x16gb sticks first and then buy another pair down the road. But I stopped myself. I spent some time reading the QNAP forums and reflecting on my plan and decided that for my use case, it was overkill. Severely overkill. At t his time, I don’t have any intentions of running VMs off the QNAP and I don’t see any plans for that in the future. That is not what I purchase it for. If you recall my previous post back in May, I never intended to run VMs on this. I want the QNAP for it’s NAS duties, data storage and VM storage with iSCSI and NFS.

Reviewing my decision, I opted to purchase 2x8GB sticks from Amazon.ca. The memory is: HyperX HX424S14IB2K2/16 Impact Black 16GB Kit of 2 (2x8GB) 2400MHz DDR4 Non-ECC CL14 260-pin Unbuffered SODIMM Internal Memory Black.

The reviews overall are very strong and positive and the pricing is reasonable. This prepares me to eventually move towards a max capacity of 32GB and that is fine with me. At most, I may dabble with Docker and containers but that won’t be much of a memory hog. I have my HP ML150 G6 Server to do any server related/virtualization duties.

Anyways, the memory was purchased and delivered. Here are a few pictures of said hardware.

Unfortunately I didn’t take any screenshots of the QTS operating system showing the previous memory utilization.

Here are a few photos of the unit and the insides.

If you have a keen eye, you will spot the official QNAP 10GBe card installed 😉

When I purchase the unit, I also found a fantastic deal on eBay for the official/original QNAP 10GBe card so I scooped it up. I’ll discuss 10GBe in the future. I’m not there yet nor testing it.

Anyways, those few photos give you an idea of how the unit looks like inside. Nothing overly complex.
When I went to install the 16GB of memory, I choose to retain my 4GB (2x2gb) so that I would have 20GB of memory recognized.

Before installing the memory, I wanted to confirm with QNAP about memory placement. I followed QNAPs official user guide located here.

QNAP States the following:

• A module is installed in slot 1.

• Modules are installed in pairs. When installing two modules, use slots 1 and 3

Being careful and identifying the slots properly, I installed my memory as shown below.

After powering up the QNAP, the memory was as expected, working and recognized.

Here is what I currently see for the hardware and resource monitor. My memory currently is sitting at 12% as I write this.

That really covers the extent of my memory upgrade. I have yet to run memtest or some kind of memory test application to make sure everything is fine but the NAS has been operating without any issues.

Last thing I want to briefly mention and this is regarding the installed AMD processor and ECC memory.

Referencing this website and it’s information on the AMD R-Series RX-421ND specs, it shows under Integrated Peripherals / Components:

Memory Controller

Memory controllerThe number of controllers: 1
Memory channels: 2
Supported memory: DDR3-2133, DDR4-2400
Maximum memory bandwidth (GB/s): 38.4
ECC supported: Yes

Interesting, ECC supported!?!??!!?!??!?!

Looking at AMD’s’ website regarding the AMD Embedded R-Series SoC, I see a similar mention of ECC memory under their Overview heading:

  • DDR4 / DDR3 up to 2400 MT/s with ECC

Under Additional Key Benefits:

  • AMD’s first embedded processor with dual-channel 64-bit DDR4 or DDR3 with Error-Correction Code (ECC), with speeds up to DDR4-2400 and DDR3-2133, and support for 1.2V DDR4 and 1.5V/1.35V DDR3 

See for yourself here.

I’d love to test this out but I can’t justify the cost of DDR4 ECC memory right now, especially for a test. If this finding would be actual, this would really win many user’s towards this QNAP/AMD box. From what I’ve read online, the TS-x73 series is great but some users want their NAS to accept ECC memory. I’m not going to debate if it’s needed or not for a NAS but I’ve seen user’s online mention that due to the lack of ECC memory in the QNAP line, they will pursue other options. *Cough* Synology DS1618+ *Cough*

If this TS-x73 line is ECC capable, I think that’s a fantastic find and something that will make this even more appealing to other users.

Thanks for reading 🙂
