And that's for Micron b-die not Samsung that was being discussed? I don't have first hand experience of clocking either but from what I've read e-die seems to be a consistently highly binned IC, whereas for example Samsung b-die has the potential to clock higher still but it was always more of a lottery as to whether you got a good batch on your modules.
>>> Yes I meant Micron B-dies. Now it makes it clear when people say "It is a lottery" for some memory kits... Thanks for pointing this out for me. Now I know why they say that.
There's an old but pretty comprehensive list of RAM dies and their performance here on reddit. They are mostly tested on 1st gen Ryzen on which the memory controller is pretty awful so you should see markedly better results with Zen 2/3.
>>>Wow nice page. I'll be checking it out for a while now ;-) *Oizon's level of Die knowledge rises to Level 2* I wonder how many levels there are haha.
As you say, dual rank modules can be harder to OC than single rank and this can be an issue on ITX motherboards where 2 DIMM slots are the norm so there's usually a trade off between OC potential, memory capacity and cost. For example, you're much more likely to be able to hit that 3600 MHz sweet spot with x2 8GB single rank sticks compared to x2 16GB dual rank sticks. The memory controller on Ryzen does seem to struggle with this although it appears to be increasingly alleviated with newer generations of CPU.
>>> Aww bad news for me. I'll just hope that 5000 ryzen can do this right. Also some guy said that it's better to have dual rank memory and get that extra little bit of performance with 100% chance than play this silicon lottery. So I'll stick with that too. Anyways thanks for this tip!
Unless you're loaded or have a very particular use case where by you need the fastest RAM available, my advice would be, don't go spending obscene amounts of money on RAM modules. Yes, 3600 or higher with 1:1 infinity fabric is the goal, however the gains past 3200 MHz are diminishing. Between 3466 and 3600 is negligible. If your build is for gaming, remember timings are just as important as frequency and you can certainly achieve better FPS by striking a balance between high frequency and tight timings. For example, a clock of 3466 @ CL16 is likely going to yield better performance than 3600 @ CL22.
>>> Yeah I've seen some tests on how RAM frequency and timings affect games. And surprisingly 3200Mhz with 14CL on ryzen 5000 / 3000 / intel 10th gen were doing better than 3600Mhz 16CL and 3800Mhz 18CL. Can't remember other timings but that was interesting to see. Also that guy who was testing it said that memory have higher effect when you are CPU bound. He tested same setup with AMD RX580 GPU and there was basically no difference at all between ram. Here is a link to that youtube video. This guy will explain everything much better that I can ;-) [MEDIA=youtube]AGux0pANft0[/MEDIA] ( Hardware Unboxed - best reviews / Gamers Nexus - best indepth reviews / Optimum Tech - SFF GOD / Gamer Meld - most accurate and fresh leaks ) - channels I constantly watch ;-P So I reealy hope to get something like 3200Mhz CL14... may be. And other timing set to some "good" value
Hopefully some of that is useful to you. Good luck!
>>> Oh yes thank you so much for this! I'm very grateful for your help.
