Ryzen 3000 processors could very well support 5000 MHz DDR4 memory
Yuri Bubliy, also known as from 1usmus from the Ryzen DRAM Calculator posted on his Twitter feed that upcoming processors will support memory at a speed of 5,000 MHz.
A few days ago more specs already leaked indicating that a 16-core version indeed is in the works for AMDs 7nm fabricated processor line. He states that Ryzen 3000 could be able to manage very fast DDR4 memory, even up-to 5000 MHz. While that is a super high (and expensive) DDR4 memory clock frequency, we do know that Ryzen always has preferred fast memory for a multitude of reasons.
Bubily mentions that the UClk, the controller's clock speed, is equal to half the module. A module of 5000 MT/s, therefore, has an effective clock speed of 2500 MHz, so the controller should, therefore, achieve a speed of 1250 MHz.

Sure they'll benefit but at current ram prices it it's barely worth getting 3200mhz you will spend as much or more on just the ram as the CPU its self.

We wont even see 5000mhz ram until ddr5.

Didn't an earlier leak say that memory support should be higher then Zen/+, but no quite as exciting as some people were hoping?
Conflicting information. Background information to such claims would be nice.

So many leaks now, gotta oil up my rumors furnace and add some coal!

Theory that Zen3 will be able to execute in SMT 3 and maybe 4 threads on single core is one I like.
Those "leaks" of XBox shown something like 8/16/24 Thread mode and may be either Zen3 based on somewhere in between since AMD is willing to do custom modifications.

afaik SMT has always been a power of 2.
I think it would be hell to get 3 threads per core to work properly.
That said, there are probably a few custom AMD designs on the board for differing partners, that could explain the disparity in the various leaks.
Never know, Sony and MS might have pretty different ideas on the chip specs and layout.
I doubt they conferred with each other about it, and will obviously try and one-up each other
As for the memory speed, since its no longer on the CPU, it is quite possible that it could reach those speeds, the IO chip having been tuned specifically for IO throughput.

Yeah, 5Ghz is blinding masses from other interesting potential.
Anyway, 5GHz is not happening on air. No way. You can OC Ryzen 2700X to 5.5GHz with liquid nitrogen and that gonna be similar story with Zen2.
Give me stable 4.3 GHz on air with improved IPC and I am happy. I am sold.
I am all interested in how new design will affect single core performance and benefits of new technology.

From what i've read here and there, ~5GHz is becoming some sort of wall that is getting hard to bypass.
Back in the P4 days, 5GHz was a challenge, even though they were made to clock high with very long pipelines.
It could be that we will stay at around 5GHz for some time on consumer chips.

on my i7, with ddr3, the controller clock has to be double of ddr3 speed. ddr3 1600 (800mhz ) needs a uncore clock of 3200mhz.
How is that that in zen is the inverse? ddr4 4000, 2ghz real clock, 1ghz controller? seems weird to me.
Any link to explain differencies?

Hopefully the motherboard makers are able to produce a board that can handle 5000 memory.
On Intel they sometimes remove memory sockets to get better tracing and speed on the memory modules, maybe AMD board makers need to do the same.

Between Ryzen 2700X and Zen2 there is a new process and a new architecture. If all they can squeeze out of it is 4300 when the old one already ran at 4100, that would be a sad improvement in the clock domain.
And not that I trust leaks 100% or anything like that, but they have consistenly shown higher clocks to boot.

Not sure what you are going on about. Ddr, any of them, your rate is doubled, hence 800=1600, and 1600=3200.
If your intel system was showing 3 sets of numbers, that is what is weird, not the opposite. It should only show 2 sets of numbers anywhere.

I think DDR4 can reach 5ghz once a cpu and mobo can handle that speed although i really thought DDR5 would make it's debut for Zen2 and X570.
The best Zen was 4.35 so i'm thinking Zen 7nm will be around 4.5 boost and maybe even 4.7 on single or two cores but only the flagship chip will reach these numbers.
