AMD Ryzen memory support

[RemusM]

These are the memory configs & speeds guaranteed by AMD for their Ryzen 1XXX CPUs:
1866 MHz for 4 DIMMs in dual channel and dual rank.
2133 MHz for 4 DIMMs in dual channel and single rank.
2400 MHz for 2 DIMMs in dual channel and dual rank.
2666 MHz for 2 DIMMs in dual channel and single rank.
Anything above that is gambling.


Update 2020:

The max memory speed (guaranteed) for Ryzen 1XXX is 2666MHz.
The max memory speed (guaranteed) for Ryzen 2XXX is 2933MHz.
The max memory speed (guaranteed) for Ryzen 3XXX is 3200MHz.
But those speeds are guaranteed only in case of 2 single-rank modules.
In case of dual-rank modules or 4 memory modules everything is degraded with 266MHz (at least).
Of course, overclocking and overvolting combined with a bit of luck (high quality CPU) can lead to higher speeds.
But again, nothing is guaranteed.


Update 2023:

Ryzen 5XXX

Ryzen 7XXX

Ryzen 9XXX

If so, you should know that "supported my motherboard" and "supported by CPU" are two very different things.

https://www.msi.com/Motherboard/B350-TOMAHAWK.html#productSpecification-section

? 4 x DDR4 memory slots, support up to 64GB
- Supports DDR4 1866/ 2133/ 2400/ 2667(OC)/ 2933(OC)/ 3200(OC)+ Mhz *
? Dual channel memory architecture
* 7th Gen A-series/ Athlon ? processors support up to 2400 MHz

You left out the Ryzen part. If you're job isn't to actually provide technical support I'd rather not have you comment on my threads anymore. I'll be calling MSI and emailing the Cooperate office and filling a complaint about the help I've received here. It's ridiculous to say the least.

Not at all.
Read again (carefully) my posted messages.
You continue to talk about faulty activities in the wrong forum section.
For future please use the right section if you want to run your CPU out of specs.

Do you work for MSI?

Quite odd question but no, Remus M is a user like you. This is a forum and not MSI tech support. Even the moderators are no MSI staff.

Oh I see. Been posting and wasting my time here then. Take care.

I've been building and Overclocking Intel and AMD computers for over 2 decades so I'm aware of MANUALLY changing settings.

But if it's NOT GUARANTEED to work as stated right on the box it's a bit misleading especially for the less tech savvy people out there. My guess is they'll get it working as advertised on the box eventually. I mean we are all here on this forum because of the same related issues unless I should just call MSI support from here on out and link to this thread for reference.

The box clearly states support for DDR4 3200OC and you guys get upset when we ask why it's not working as advertised or if you know if it will indeed be supported. I don't think I'm in the wrong for asking especially being a long time customer loyal to the MSI brand.

It's quite clear you're not understanding, no matter how someone explains it to you. 

Does the CPU support it? Yes.
Does the board support it? Yes.
Have you set it up properly? Apparently not. Others have managed to get it to work properly. So obviously the motherboard and CPU support it. Maybe your memory doesn't? Maybe you just aren't using the correct settings? We really don't know. But coming here and getting mad, and harassing users and moderators about your 'experience of over 2 decades' (most of the mods experience eclipse that....so it means very little at all to us) isn't going to change your problems, or fix it. 
We are here to help, but getting hostile is a one way street to being removed.
We would gladly help, but with little to no information, other than complaining, there is very little we can suggest.
Not only that, this is hardly the place to do it. I really suggest opening up your own thread and explaining it there.

Lastly, RemusM is a memory expert. Much more knowledgeable than many when it comes to memory and memory support, especially in regards to AMD systems.

Because the entire MSI forum is bloated with topics related to AMD Ryzen CPUs and B350 motherboards.

1) The XMP (overclocking) profiles have been designed by Intel for the Intel CPUs.
They are not even guaranteed by Intel to work on any Intel CPU.
Trying to make them work on the AMD CPUs is gambling.

2) At these moment these are the memory configs & speeds guaranteed by AMD for their Ryzen CPUs:
1866 MHz for 4 DIMMs in dual channel and dual rank.
2133 MHz for 4 DIMMs in dual channel and single rank.
2400 MHz for 2 DIMMs in dual channel and dual rank.
2666 MHz for 2 DIMMs in dual channel and single rank.
Anything above that is gambling.

Well with the 1.27 beta bios I have 4 single rank dimms running stable at 2400 mhz.Thet are Corsair Dominator Platinum 8GB dimms I out framvoltage at 1.35 volts enabled extra overclock protection on voltage .Ialsohave a stable 3.7 GHZ overclock on all cores. Perhaps I will try to raise it to 3.8GHZ,as I have an excellent  liquid cooler,an AlphacoolEisbahr 360. It has a large,but thin 360mm copper radiator. My Cinebench R15 scores are through the roof. 98.4 fps, 1610  for CPU,and 855 single core. I also have a 2GB ramdisk that I use to accelerate Firefox and copy dvd programs to and then install them almost instantly avoiding slow DVD installs because of their poor access times..
 If I could only get MSI to iron  out iwindows installation problems from the m.2 NVME slot formy Samsung 950 PRO drive.

I'm having a great experience with my 960 Pro, in fact that's the one piece of hardware that hasn't had any issues on this build.

 

[Riptide]

Everything has worked well for me other than Trident Z 2x8GB CL14 modules that aren't on the QVL for the Tomahawk so I have them clocked down for now.  Figure I'll be patient and wait a few months before I give up on it.  I knew this was more or less a Beta test I was getting myself into.  MSI deserves some time to work on memory compatibility.  Hoping my modules are eventually good for at least 3000 on this motherboard.

Hello,

I hope I can receive some help here. I bought this kit: https://www.gskill.com/en/product/f4-3200c16d-8gvkb It was on sale and RAM prices were going up. This was before all the RAM stuff came out, so I figured why not? Guess that was a bad choice in the end.

I have a x370 MSI GAMING PRO CARBON. I can't get these to run at their advertised speed, no matter what I try. XMP on, off, manually entering timings, trying to add a bit of voltage, nothing. The max I can get them to do is 2400MHz. 

Any advice for me? Should I try and sell this kit and get something else? I'm pretty bummed out. I know I shouldn't have bought the kit, before Ryzen came out. It's not on the QVL list of the board either, but new ones are being added though... 

I figured I'd be okay, because the board does support 3200 MHz RAM. Does that mean these sticks will be supported if I just wait it out? Any rough ETA?

Here's the thing. You could hold out and hope that AMD/MSI or maybe G.Skill provides some help or an update to make them work at 3200 MHz. 
You could sell them, and get something a bit better (and more expensive) in the HOPES that it works at 3200 MHz like you want.
Or you could just be happy with 2400MHz. 
Personally, the jump in 'speed' relative to 2400 MHz to 3200 MHz is maybe 10% in the BEST cases, but most likely that won't be realized in most use-cases. I'd be happy it works, and it runs at 2400 MHz.

I feel like an idiot running 3200MHz at 2400Mhz though. I could've saved some money and bought 2400MHz RAM then. Not to mention the board states 3200MHz is supported. I don't mind it not being supported at launch, but I do hope it'll be supported in the near future.

Rated memory speed is simply the *maximum* supported speed. Not unlike a freeway with a 75MPH speed limit where most people may be stuck doing 55 due to traffic (yes, imperfect analogy). I bought DDR3200 to give me extra headroom to make 2400 easier to achieve with the hope of eventually reaching 3200 (at the time AMD had only confirmed DDR4-2400 support). I actually could reach 3200 if I dropped down to 2 DIMMs from what I am seeing from others who use the same memory, but I would rather have the 32GB (not that I need it at this moment, but I do occasional video editing). The speed drop really doesn't matter to me. As already noted, the actual real-world impact is rarely significant. Now, that being said, the new Ryzen architecture is unique in that the actual memory *clock* speed does directly impact the IMC and Infinity Fabric, but the impact on anything other than benchmarks again isn't likely to be significant.

Also, it's not unusual to get better IC's in higher rated DIMMs. It is quite possible DDR4-2400 DIMMs may not even reach that rate on the AMD platform if they use lower quality IC's with worse compatibility. Some benchmarks I have seen (early after the Ryzen release) showed AMD memory bandwidth at >95% efficiency versus ~75% efficiency for Intel (I would assume this relates to the integrated IMC on Ryzen).

Quite a few reviews out there showing 10-15% difference in some videogames with different memory settings. That's a lot in my opinion.

If you have a decent graphics card, the memory speed is almost irrelevant (2-3% boost from 2133 to 3200 MHz)

I think it's been said now a few times this isn't the case for Ryzen, for whatever reason. Look up reviews with games like Fallout, Crysis 3, The Witcher 3. The difference can be as much as 15%, which results in 10-20FPS differences.

https://www.youtube.com/watch?v=TId-OrXWuOE just an example.

Anyway, I see my question is not going to be answered. I asked about ETA and possible fixes. Not excuses for why running 3200MHz at 2400MHz is acceptable, when I've spent 200 euro on a board. I'm not blaming MSI here, the launch is a crapshoot, probably cause of AMD, but I'd like a (rough) timeline for fixes.

I really think that in the first post we should list that single sided samsung memory has had the most compatibility with overclocking. anything else won't go over 2400... 2667 if we are lucky. 

I went from Corsair LPX 3000 which would not post over 2400 no matter the setting or bios, to LPX 3200 memory and was able to get 3200 on the first try.

  According to the memory speed chart with 4 dual channel ram slots filled witj first ranked dimms I should only get a speed of 2133mhz.Yet with my four 8GB dimms I was able to get to 2400mhz quite easily on bios 1.27. When the bios is completely optimized I expect 2666mhz memory speed.

Hello,

I've a question regarding memory support. My specs are in the sig. Since search on this forum is a pain and i didn't want to read all pages please don't be hard to me if this has been posted earlier.
Apart from endless post-time my system runs ok on 2133 JEDEC RAM-settings but when i change to XMP my system boots and reports 3200 with advertised timings in bios but on every boot it outputs 4 beeps by internal speaker.
I'm on BIOS-Version 115 atm and the memory is listend on MSI's doc to be supported with 3200.
Reverted back to JEDEC then without doing further testing since i want to have the system running stable first.
Anyone has some advise on this issue?

Thx for your answers.
