AMD Ryzen 3000 "Zen 2" a Memory OC Beast, DDR4-5000 Possible

[JAB Creations]

Being able to overclock the RAM with all four dimms is important to me. I doubt I'll have 5GHz RAM though as things improve for me I'd love to benchmark the RAM differences and release the information myself about how much it's worth buying faster clocked RAM plus the difference between two and four dimms. I'm very grateful that they took the time to really iron out the issues that have been mentioned and it's my hope that the 3000 series Ryzen Two generation will be as rock solid as possible.

So you'll need a new mobo for this?

Maybe. Obviously you'd need a Ryzen 3000, since it contains the memory controller.
Judging by how I at least presume the information was collected, I'm guess it's from a UEFI update for current boards, so it might stil be possible on non X570 boards.

AFAIK the main reason of using high speed memory in Ryzen (gaming) setups is to pump up the speed of the Infinity Fabric, because if it can't hit at least 3-3.2GHz, there is a slight lag every time the scheluder throws a thread from one module to another.

As a Ryzen 1700 user I never had issue using it on stock speed, but since I use it with stock memory speed, there could be a spight jitter on less multythreaded (older) games. For example: MarMax.

Highly multythreaded applications are less affect d, because if it uses all 16 threads, the scheluder can't throw any of it to another.

And honestly I failed to see the advantage of a 5GHz memory in comparison to a 3GHz one under gaming applications.

I'd assume top tier boards only that have the necessary power delivery.

Let's get past 4.2 GHz for CPU and 3600Mhz for RAM first before making up fairy tales

Yes fairy tales cause its unlikely they would improve the ram capability and base clock like they did even with the interim ryzen +

 

[Midland Dog]

Wouldn't the 1/2 divider pose a small problem with decreasing IF clock when it gets enabled?
Assuming without divider memory goes to 3600 (roughly how it is now), going from 3600 to 4000 and enabling the divider to facilitate these speeds would mean IF clock going from 1800 to 1000, right?

IMC is in the CPU, so divider support in BIOS could theoretically be available for older boards as well.

IMC is on the I/O die

But even at DDR4 4000 , Those kits are expensive.

2700X does both.

I agree.

In my country the ram prices for 2x8 GB DDR4 kits are:
-3000 CL16 kit 80 € - G.Skill Aegis
-3400 CL16 kit 105 € - Patriot Viper 4
-3600 CL17 kit 124 € - Patriot Viper Steel
-3733 CL17 kit 143 € - Patriot Viper 4

Everything else faster is much more expensive, and everything else slower isnt really cheaper than the 3000MHz kit. So I'm wondering what kind of ram will be optimal / acceptable for Ryzen 3 with a reasonable price with reasonable performance for gaming only.

Also from what RAM frequency will we need to enable the 1/2 IF speed multiplier? And how will it affect the CPU's performance..?

Depends on which CPU you get, no? Afaik, there's no power increase unless you go over 8 cores.

Done.

Unknown at this point. AMD apparently tests with G.Skill, Corsair, Kingston and one or two other brands. This doesn't mean that the board makers will optimise for the same kits. Once boards are available, check the QVL for the board you want and buy accordingly. It's highly recommended to do this to start with, if you want to use fast memory.

Unknown at this point, but I'm sure we'll find out more as soon as hardware is sampled to review sites.

My 2700x has no problem doing that, in fact I can do 4.3ghz + 3600mhz no problem. I scaled it back to 4.15 though. I need them to be able to at least go 4.8 all core + 3600mhz.

 

[Roddey]

Well on this news I went ahead and bought the Viper Steel Series 4000mhz. I dont know if the tariffs, the release of AMD 3000, and the cancellation of b-die will effect the pricing of these but I took a guess they might and bought a little early. There not going to be delivered until the end of May and I will have 30 days(if left unopened)to decide if I keep them or return them for a refund. The price is locked in though for almost 8 weeks.
Time will tell I guess.

So it has support in the bios for DDR4 5000, doesn't mean anything, my Asrock Ab350m has support for DDR4 4000, it still doesn't get anywhere close to that the same as all other current gen and 1st gen Ryzen boards and processors. That said if Ryzen 2 can hit 4000mhz DDR4 with 4.5+Ghz chiplets available then that is more than enough for my and many other peoples needs. The interesting this is the seperate I/O chip that replaces the on die memory controller, maybe they have overcome many of the limitations of Ryzen and Ryzen+ memory issues.

The specs sheet of Asrock B350m shows 3200+(OC) mhz speed. I'm curios where didn you saw that 4000mhz for that board.

Where's the quote for this?

In the review for the Asrock x370 Taichi. Earthdog went over the details there to highlight why that board and Asrock team was so awesome.

I dont think that was me.... I've never reviewed anything x370.

 

[infrared]

I can't wait to see how a 3700x behaves in my Crosshair VI, I've have 3600mhz stable this board, and remember @cdawall getting over 3700 so I'll keep my fingers crossed. If I can't reach at least 3800mhz I'll have to get an X570 board as well.

Um?! Even my 1800X is capable of those clocks for benchmarks.. even a sub-par 2700X can exceed those with ease.

 

[RH92]

There are a lot of improvements in X 570, MSI and ASUS are preparing legendary tops

Is really X570 going to play that much of a role in memory OC ( other than the multiplier you mentioned ) when we know that the MC is on the CPU ? I mean motherboard manufacturers said the same about X470/B450 compared to X370/B350 but it turned out that there was basicaly no difference between the two when Zen+ was used .

On the internet, from around when Zen launched. I'm not going to spoon feed it to you

for all intents and purposes, 4.2 ghz and 3200 mhz is about it across the board. Anything past that, especially on core clocks, is gravy for any ryzen. Memory can get up there, but you need the right sticks and proper bios/aegesa.

Benchmark stable, if done right, isnt 24/7 stable.

Looking at the price of RAM, you don't really want to go over 3200 anyway. Though you may have the budget if you're buying a 16c/32t CPU.

Don't be ridiculous, you can make anything true on the Internet, I want to know where amd said this, oh you won't spoon feed me because its not true
