NAS Build - ECC Compatibility

[DTV998]

Hello,

 

I'm planning on building my first NAS; this is the first time I'm dealing with ECC memory so I just wanted to get a 2nd opinion (in case I'm missing something...)

 

I'm planning to go with a 5650G + ASUS Prime B550 Plus + Timetec Hynix Unbuffered ECC (71TT24EU2R8-16G x2) // as far as I'm aware, these should be compatible (The Ryzen Pro supports ECC; the Asus Prime as well & Timetec is DDR4 ECC Unbuffered); however, I was unable to find any "official" compatibility as Asus' website doesn't seem to have a single Timetec product listed as compatible memory & the Timetec mobo support listed in the amazon listing doesn't show this motherboard (however it shows some very similar previous generation motherboards; I'd guess that's because the compatibility list was made before B550 existed).

 

TLDR; Should these components work & enable ECC;

Thank you for taking the time to read this!

Looks fine in theory, but in regards to the actual support and logging capability, I don't know. There used to be a list on reddit of motherboards with confirmed operable ECC.

 

I haven't seen the Pro CPUs tested much either, so I'd suggest doing some research there too.

Do you really need ECC memory?

tbh I probably don't REALLY need it; however I'd like to do it properly & it might become useful down the line with VMs/webapps/servers...

As far as I understand it, non-ECC would mostly only be a problem (TrueNAS) when you're writing files to the NAS (if a bit flip would happen while the file is still in memory, there would be no way to know that part of data is corrupted until you'd eventually check out the file yourself...)

Yes; quite annoying they were OEM-only for so long; mainly going for the 5650G instead of an X version CPU because of the high idle power consumption of chiplet CPUs (compared to monolithic)
