Windows 10: Looking for more memory

I want to buy & install more RAM in my PC. I currently have 16 gigs (8x2) and want to maximize it to 64 gigs. I guess that means I gotta get four 16gig sticks. I looked at Newegg and found these Crucials for around $500.
Crucial 64GB CT4K16G4DFD8266 - Newegg.com
Tomorrow is New Years Day so I'll wait until at least then before I make any buying decisions. They might be on sale then, who knows.
They're the right voltage (1.2v), don't want to exceed that. I don't know what an "unbuffered DIMM" is (UDIMM), I'm at a loss there. *sarc

Anyway, any ideas you can throw at me I'd love to hear them. Thanks!

Overclocking / Undervolting guide for Vega 56 or 64?

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

Step-by step overclocking in Wattman
Fan speeds
Power limit
Temp limit
Voltages
Core speeds
Memory speeds

 

Choice of memory and motherboard... a bit stuck...

No one who got some suggestions on this one, huh?

I've found out that the Asus M3A78-T needs to be flashed, so then that motherboard is excluded from my list. Which motherboard and memory should I then go for? Any suggestions?
