I ordered and received the QNAP TS-464-8G in December 2023 (shipped and sold by Amazon) and the memory WAS upgradeable. I noticed other reviewers complaining that their 8 GB QNAP was not upgradeable with regards to memory, but mine did not have that issue. Finding that was the case, I decided to upgrade the ram. There were two so-dimm slots on the motherboard; one slot populated with an 8 GB stick of ram and the other slot was empty. There was a sticker on the stick of ram that was pre-installed in the unit, with a note that the warranty is void if removed. So I decided to leave that stick of 8 GB memory in place in order one stick to add to the machine. Normally I would have two matching sticks, but I did not want to void my warranty. I went to crucial's website, used the find compatible memory tool, and ordered one of the 8GB single stick part numbers from Amazon. My TS-464 is now purring along with 16 GB of ram with no issues to report. I have only been puttering around with this NAS for a few days and I'm new to using QNAP so it is a little bit of a learning curve to find my way around. It could/should be easier to set up and configure. Part of the reason I ordered this particular model is because the processor has 4 cores and supports hardware transcode with the integrated graphics, which is good for Plex. Performance seems good and everything runs okay so far. At the moment I rated this four stars but I will be back to update if I encounter anything else bad or good to share.
After getting more experience with the TS-464 and a TS-664 I'm changing this review to 5 stars. I like these NAS very much.
