tvs-675 RAM upgrade

QNAP TVS-675

First of all_THANKYOU for brilliant information in your reviews. If ever allowed out of this C19 caused police state and visiting mates in England, I’ll buy the beer!
On your advice I placed an order for a TVS-675 NAS to replace my old TS-669Pro.
I live in the country and need to drive to sydney to pick it and the 6 IronWolf Pro 8tb drives, but BEFORE I leave I need also to update the RAM to 64gig and the two SSDs.
Your review was RUSHED and I could not make out what you were saying re the correct TYPE of both RAM and SSD.
Would you PLEASE make it idiot proof for me and give me a specific brand and model number for each?
Armed with that I can then be specific and the boffins behind the counter supply me with EXACTLY the CORRECT goodies.
The last time I built up a computer was ovet 10 years ago (and it’s still working fine!) but things have moved ahead so much in that time that I couldn’t understand most any tech stuff you mentioned.

Qnap TVS-675 comes with a not much tested Chinese CPU. We have not tested it and have no hopes this is a very future proof model. But it might be.
TS-669Pro was an Atom-based model which is not actually that much different performance-wise. But Intel chips do last longer.
Adding more RAM is rarely speeding up the NAS. People add more RAM when apps actually demand for it. Especially when they run things like docker,VMs or webservers.
