ram Choosing RAM on a 2950X/ ASRock X399 Taichi

[demoan666]

Hello everyone

I am getting a PC built on ASRock X399 Taichi + 2950X Threadripper. confused with RAM (my requirement is 4x16 GB= 64 GB), I could use some good recommendations and advice  

Here is what i found out from various forums:

1. TR 2950X on an ASRock X399 Taichi can not go beyond 2933 Mhz
2. G.Skill** is the de-facto/ default RAM recommended for this setup to ensure most efficient and smooth running of this Processor and Motherboard combination

**Here is the most recommended RAM by G.Skill Official Website and their QVL for Asrock X399 (+ also recommended in different forums in the internet and youtube videos):

My puny brain can not understand the following:

1. I am making this to primarily (learn) run Simulations on this PC - what is the difference in speed between the 14 CL faster and 16CL CAS? (mybe in percentage or an example)

2. of those four RAM (in the above link) all are "for AMD" however only the 2933 Mhz QVL says "ASRock X399".

And on the 3200 Mhz there is no mention of ASRock X399 on the QVL.

Does anyone know if the 3200 Mhz is not in the QVL because the ASRock X399 can not go beyond 2933 Mhz (i,e. if i put the 3200 Mzh RAM it will run but only at 2933 Mhz)? and that is the only reason. OR there are other factors as well?

3. Does anyone have any experience if the 3200 Mhz RAM runs with TR 2950X on an ASRock X399 Taichi without any problem?
Basically i am asking if I buy this (https://www.morele.net/pamiec-g-skill-flare-x-ddr4-4x16gb-3200mhz-cl16-f4-3200c16q-64gfx-6470691/) will it will run just fine with the TR 2950X on an ASRock X399 Taichi ?

4. Why the G.Skill FlareX 2933 Mhz RAM Costs more than 3200 Mhz?!

 

I hope i made sense with my words!  

 

TL;DR: I do not want to spend a lot of money on RAM----> Also me: scared to get cheaper RAM and have significantly low performance/ incompatibility----> Desperately in need of advice! 

thanks a lot in advance!
