Ballistix Sport LT 32GB (2 x 16GB) 3200 $165 (w/ $15 instant savings)

Available on Newegg :-
It is not Samsung b-die; rather it is Micron memory with reasonable timings
Compatible with Ryzen
A lot of memory deals available, but this one caught my eye:-
1. I had narrowed my 64GB kit down to the 3200 Ballistix Sport 4×16
Seemed to have the best Ryzen compatibility at this $400 price point
2. You can purchase 2x of these kits to get 64GB (you can get $30 instant savings)
Fully supported by Micron
Anyway, $330 for 64GB of 3200 Ryzen compatible memory seemed like a good deal for today.
