Single Rank vs Dual Rank, Samsung E/D-Die vs Samsung B-die.

[purrfected]

Decided I finally want to get some real memory, atm I have micron b-die 2400 Mhz. And it's impossible to get them above that sadly. I use a GA-AX370-Gaming K7 motherboard.

So, I started to look into something with samsung b-die originally, that's when I started to learn about SR/SR. Always wanting to min/max I had to figure this out.

I found this reddit post:
https://www.reddit.com/r/Amd/comments/7780t3/single_rank_vs_dual_rank_ddr4_benchmarks_at/

And from other forums I've also heard DR is actually better.
I've been trying to find a similar test with samsung b-die though, specifically samsung b-die dr vs samsung e/d-die dr.
But samsung b-die sr vs samsung e/d-die dr is also of interest.

Problem with samsung b-die dr is that there are hardly any sets with that chip in dr. They are only in 32 gb packets. And I really could survive on 16 gb, but, if it will give me an improvement in score, I will go for the samsung b-die dr for sure.

So, what do you guys think, are b-dies so much better from samsung than the e/d die?
Also considering binning and possible subtiming tweaks.

I didn't benchmark anything but I just recently went from DR E-die @ 3200C16 to SR b-die @ 3466C14 and the difference was noticeable. Dual rank is harder on the IMC though so might not clock above say 3333 as easily. If you have a good IMC though, dual rank b-die at 3333/3466+ will blow everything away.
