I own a MSI B350M Bazooka motherboard and this RAM is made with real 16 Gb chips and 16 chips, 8 on each side. A measly $245 a stick right now but price rot will bring it down to where I like it. JEDEC has 16 Gb in the spec so this is now the top deck for DDR4 unless JEDEC amends the standard.
M378A4G43MB1-CTD may be a part number but nothing on NewEgg or Amazon yet
Amazon has the server version but Samsung has unbuffered in their catalog.
So I wonder if MSI and AMD are going to let me install these on my B350 based motherboard and have the insane 128GB of RAM on an AM4 rig
Cram it with RAM.
