Not all Samsung B Dies are made same. I have a kit that is B Die alright, but does not go past 3200C16. It was originally rated for 3000C15.
I have tested around 50+ different kits in DDR4 with Zen+, Zen2 and Zen3 on B450, B550 and X570 boards.
But if originally rated for C14, then this kit is the better B die. Since it is 32G kit, most likely dual rank too.
Fact that it does 3600C14, means this is simply the 'best of the best of the best'. You simply can not get anything better than this.
Even though the market for extreme high end DDR4 RAM kits is niche (Mainly Ryzen 3000 benefits the most, 5000 sees diminishing gains), for the price, I feel it is pretty good.
Micron E die are the next best thing, I currently run a kit for 3800C15 with 1:1 for Infinity fabric, for my 5900X on X570. I purchased that 2x16GB kit for around 8000 from TheItDepot (new).
