Synology RS1219+ RAM Upgrade Question?

[Enquiries]

I'm preparing to upgrade the NAS I requested for my workplace, and I have the doubt if I can install ECC RAM on it. It's a Synology RS1219+ and while Intel (https://ark.intel.com/content/www/us/en/ark/products/77981/intel-atom-processor-c2538-2m-cache-2-40-ghz.html) lists the server as ECC-compatible, I've yet to see any comments on actually installing ECC memory to this NAS (like 2 x CT102472BF160B).

Also, I want to add a 10GbE card like the Intel Intel X540T2, but heard on another video guide that another intel card failed to work on this server. Is it possible to use?

Thanks!
