Memory Need to find the right 2950x ram kit

[O_and_N]

Hello guys
I have a amd 2950x and a asrock x399 taichi and i need to find a 64gb ram kit ,quad channel, composed of 4x16gb sticks that will run at least at 3200mhz xmp stable.I checked the asrock qvl list but there isnt enough info/tested stuff there.Which gskill kit coud achive that speed stable with that amount?
I did saw this kit :
https://www.gskill.com/en/product/f4-3200c14q-64gtz
But it says that is dual/quad channel kit and i dont understand this.It means that is dual channel if i use only 2 of the 4 sticks and is quad channlel if i use all 4 sticks?

There is also this thing
https://gskill.com/en/product/f4-3466c16q-64gtz
but is cl16 and that is not a samsung b-die, and i understand that that is what threadripper likes.


Any way, what coud you guys recommend me?
Thank you.

Have you tried the B-Die finder?

Never knew about this page.Thank you.
Does this finder really finds only Samsung b-dies?Im asking as its showing me some cas 16 memories and 18 and I was left with the impression that b-dies were only restricted to cas 14?(or this is wrong info that I got)

Cheers

Typically, the higher CAS numbers are on the higher speeds. Click on the >3200 speed settings and the CAS number goes up.

They are likely the same chips with different XMP profiles.

You can match these with the QVL list for your motherboard. They usually verify if b-die is used on the ram but not all speed/sizes are checked.
