Is the whole B-Die thing with Ryzen CPU still a thing?

I have a 2700x running with a B450 Tomahawk board and a set of 3000mhz Corsair CMK16GX4M2B3000C15.

Research tells me these aren't B-Die. They work fine at the rated XMP profile, but I feel games aren't particularly smooth. This was the same feeling I had a few years ago before upgrading from 1600mhz DDR3 to 2400mhz.

Is the whole B-Die thing I'm reading about still an issue with the newer Ryzen CPUs? Would it make sense to ditch the Corsair RAM and get something with "b-die"? I'm wondering if this could explain the lack of smoothness I experience.

B-Die just comes with (typically) better out of the box timings and they OC better. If you run your B-Die at the same speed/timings as your Hynix/E-Die kit they're going to perform identical.

Though your games should be "smooth" at 3000 CL15. You'll get a bit better performance but I'd imagine your issues are elsewhere.

Ah ok... i thought there was an inherent flaw or compatibility issue with some types of RAM.

If it just means a better die from factory, then no need to change

It could just be the game is a big crap at running rather than my machine to be fair!

A lot of the Ryzen woes wouldn't have come up if people were checking the QVL. With the 1000 series pretty much all ram was optimized for Intel plus it was a new CPU and chipset so yeah people had issues getting rated speeds out of various kits. Since the IF benefits from faster ram it could have been a real issue for some people.
Now though it seems to be much better but even if it's B-Die I'd check the QVL first so you know you'll get the rated speed without any fuss.
B-Die in general is simply better ram, it's able to hold good timings at higher speeds pretty much.
3200mhz is the lowest kit I'd get with Ryzen but Ryzen or Intel I'd buy this kit in particular:
https://www.amazon.com/TEAMGROUP-T-F.../dp/B07H27C8JZ
Cheap, fast and b-die


However since you already have what you have you might as well try overclocking it first so you can see if it's really the ram or maybe something else. If it won't OC at all you could also lower the speed to see if the problem worsens.
Lack of "smoothness" could be something totally unrelated but I'd say you're probably right.

3600MHz (PC4-28800) CL18 is B die? I wouldn't think so. That is fairly slow ram. You can get 3200 CL 14 Ripjaws for a few dollars less than that which is confirmed B die.

That's weird, there's an identical kit that's cas 16 that I can't seem to find anymore, was on Newegg last month.
But yeah all TG 3600Mhz is B-die, most 3600mhz in general is.
Even being CL18 it's not a bad deal if you're planning on tweaking it.


https://www.newegg.com/Product/Produ...82E16820232476
3200mhz B-Die for $130 (next 6 hours)

So quick question leading on, when I bought the RAM for the same price Corsair offered:

3000mhz CL15
3200mhz CL16

Is one actually faster than the other? I assumed the higher speed, but slower timings would mean they are both about equal.

Thoughts?

Could be the same exact chip or not. You can get the same exact spec RAM and they can be different. Generaly you have to look at speed,timings and voltage.

If you want to see some results from my testing DDR4 Ram in some games at 2560x1440 with different speed ram

Or here is quick 3 games

Interesting results there. Obviously there is a significant difference in RAM speeds then.

Can anyone suggest a b-die 16gb kit that would run at 3400mhz out of the box?

I know there is a B-Die finder website, but it's a lot of links... So perhaps someone can recommend me a kit? I'm in the UK, but can also check amazon US links 🙂

Thoughts:

G.SKILL F4-3600C16D-16GTZR 16 GB (8 GB x 2) Trident Z RGB Series DDR4 3600 MHz Dual Channel Memory Kit - Black with full length RGB LED light bar
