64GB RAM upgrade on ts-873a and ts-h973ax


May I know if going to install 64GB RAM on QNAP TS-h973AX will it able to see 64GB RAM installed? as I watched your video (64GB, 32GB and ECC memory in the QNAP TS-873A NAS – Memory Upgrade Test) TS873A and TS-h973AX are using same CPU.


 


Yes, the limit is always based on a CPU, not the NAS model.


So in this video, we tested Kingston 32GB memory which worked and also could be used in virtual machines.


Kingston 32GB memory kcp426sd8/32 DDR4 2666MHZ: USA   UK 


Samsung 32GB (no tested but should also work)   USA   UK


 


 


Yes, you can upgrade this NAS with ECC memory. This will require removing the existing non-ECC module. But this is the right thing to do if you want a more reliable system. Not only ZFS files system can benefit from this, but any other file system too. Very useful for things like VMs, web servers etc.
Here is a list of Qnap ECC RAM:
