micron e-die vs b-die for 3900x

[SnooPainting8310]

Which one do you think will overclock better with a 3900x ? (mobo : b550 aorus elite)

Apparently micron is better for ryzen 3000 end b550 mobo ?

Rev-E is easier on the memory controller compared to Samsung B-die, so it's a pretty good option for Ryzen.

You probably won't be going over 3733/3800MHz anyway though, and a 3900X will probably be okay even with B-die at those frequencies, unless you just get really unlucky with the memory controller in which case different memory ICs probably won't help you anyway.

no, not really. 

 

B-die does timings better, while Rev E does frequency well. 

 

and since you essentially have a frequancy ceiling of 3800mhz, you should tighten the timings as much as possible.

Is latency still that important if I don't game at all ? I have no interest in fps...

it helps overall performance if the task is latency sensetive. 

 

idk what work you are doing, if it needs bandwitdth, then you should go 2:1 ratio and loose timing Rev E. but it really depends on the task

The task I do don't use ram speed or latency the only important thing is the quantity of ram, but the software I use is only cpu reliant. So is latency very important for my ryzen ? more important than speed ?

idk,. it highly task dependant.

ok bought the e-die..

the Rev E. 

 

fair enough. its significantly cheaper, so why not get it. 

[SnooPainting8310]

Yeah the rev-e and I got them sold to me enough from redditors... as i also posted threads there to ask (also here and there)... As of now my final opinion is that b-dies have definitely better raw performances but they aren't worth the 30 euros diffs for my current usage.

 

But hell ram optimization seems light years more complicated than cpu overclocking...

Unfortunately that is also a benefit to b-die.  It's been around forever and since so many prefer it there's lots of into about what it can and can't do.  People are still learning on these newer die types.

How is that unfortunate ?

and people have learned that these newer dies might clock well, but they dont time well. and that newer ICs are generally made to yield JEDEC spec. so you wlll generally find that the older dies are kinda the "best"

In that you went with something else and that you won't have the data from others to help with the light years more complicated RAM overclocking.  Though that might make it a more fun endeavor.

Oh found quite a lot of people using rev-e on my quest on reddit... Some of them even shared their numbers set up, one was even running at 3800 c14 !!!!! to me that's exactly what I want to do and I won't make further digging when I will achieve a similar result.. (like 3800 c16 would be fine) That's litteraly my end goal with those ram, without going over 1.45v (is 1.5/1.6v daily fine thou ? for rev-e )

What do you mean by they don't time well ? I think someone pointed out something similar in that thread's comment (watch the "debate" between @MemoryDemonstration and @malphadour)

 

This 2 days old thread is also very interesting : https://www.reddit.com/r/Amd/comments/irjwaa/version_2_sorry_for_ryzen_zen2_owners_simple/

they dont run tight timings all that easily. 

 

something B-die does well, meanwhile CJR and Rev E clock fairly well.

Ohh ok... I see

 

Also I just learned about the FlareX rams (for amd)... How better a 3200 c14 kit would perform compared to a 3600 c16 on a benchmark like cinebench20 ?

as i said, ram is very specific to tasks. 

 

and cinebench is one that doesnt care a lot. 

 

also "for amd" is just regular memmory, id just get cheap rev E

The new die types, smaller IC, doesnt scale on voltage well. This fact is why mainly B die is an overclocker enthusiast choice over any other die make out there.

 

Woomack at OverclockersForums.com would be the guy to ask while this man has tested quite a good variety of memory. Pretty sure he has a dedicated thread too. I'd link it, but it seems like everyone here knows their shit.

 

Choose between E-die and B-Die? 

I'd choose the B.

The RGB is what makes the memory expensive.

For you Nick, look at Newegg business for a nice kit 16gb 2x8 - 3600mhz 16-16-16-36 1T for 99$ no rgb. They will do 4000mhz on the XMP timings.

Thanks for that.  I bought a 3600C15 kit recently for $125 and a 4400C19 kit which is $35 cheaper now so it's really an attractive deal at $159.

When my 4267mhz kit was released 2x8gb was over 300 bucks. Now about half of that. 

 

I run them at CL 14-14-14 for benching 1.60v

That new 3600C15 kit was half as much as I paid for my first kit.

Thanks for that.  I'm pretty sure I stumbled across that before buying my 4400C19 kit, but I didn't really give it a read as it didn't have the kit listed.
