Memory compatibility is down to the board, or the CPU?

For Science!

Dear All,

 

We are considering buying some Threadripper 2 CPUs, but I was wondering since the X399 boards are largely unchanged, whether supposed improvements in memory compatibility with Zen+ is expected for these CPU/board combo. For instance I have a X399 Asrock Fatal1ty board with a 1920X that really struggles with the particular 128GB Kit that I have, If I upgraded to a 2950X is it reasonable to expect any differences or is the motherboard the sole determinant of memory compatibility?

 

@The Benjamins?

According to AM4 experience, memory OC depends more on CPU, but mobo also has some effect.

 

New X399 boards share the same microcodes for the memory controller as old X399 (AMD said memory OC gets better because of microcode updates, the imc remains the same on all Ryzens). you should get all the benefits of 2nd gen Ryzen without being hampered by the motherboard.

It might be better with the 2nd gen Threadripper but you have no guarantee of that so it's a bit of a lottery. Though I believe that it can't be worse.

I am not 100% sure but both motherboard and CPU effect memory compatibility. But the new generation 2 TR should help improve compatibility.

It is the same improvements as 1700x to 2700x.
