Bem, eu tentei fazer um flashback da versão do BIOS para uma mais antiga que eu tinha antes (7C37vH4), e está funcionando agora com 4 sticks a 3200 MHz com xmp habilitado.

Eu não sei por que ou o que eles mudaram depois dessa versão, eu basicamente tentei todas as versões que estão disponíveis e esta parece ser a única que funciona com os 4 sticks, tente eu acho.

Esperamos que alguém que tenha mais conhecimento sobre isso tenha alguma solução para esse problema.

This version (7C37vH4) accept Ryzen 7 5800x?

almost 100% it will not accept , what i have read , u can just use 2 sticks with the rated speed or use the 4 sticks with xmp disabled . Or u can try to adjust the timings and voltages by hand at the bios and see if u can get it stable.

ON the MONEY it is so

Well, I tried to flash the BIOS version to an older one I had before (7C37vH4), and it is now working with 4 sticks at 3200 MHz with xmp enabled.

I don't know why or what they changed after that version, I basically tried all the versions that are available and this seems to be the only one that works with the 4 sticks, try it I think.

We hope that someone who is more knowledgeable about this has some solution to this problem.

This version (7C37vH4) accept Ryzen 7 5800x?

If using 4 modules then 3200 should be stable anything over that is just sheer luck and the bigger the ram modules the less chance of clocking over 3200.

If ya had just done some research you would find that most to the 4 stick running over 3200 are 4GB or 8GB modules. With 16GB or 32GB sticks you just about [***CENSORED***] out of luck no matter the speed rating on the ram packet.

I researched if the motherboard accepted. And my modules are 3733 16GB each. stable at 2x16GB at 3733 plus 4 does not go up.
I saw another forum a person speaking that rises in 3600.
Wait for the publication of the announcement "MSI starts to release AGESA ComboAM4PIV2 1.2.0.0 BIOS" and see if it goes up.

Look at the response from MSI support, unbelievable.

Dear Lula.fisio,

Thanks for contacting MSI technical support.

Regarding your concern, according to memory test report, we have tested two sticks of HX437C19FB3A/16 RAM, and they can work well at 3733MHz. If you use two kits of them, we cannot guarantee the overclocking performance.
In addition, all of RAM kits are paired to work together within their own kit. We don't suggest you mix 2 kits together even with the same part numbers. Even without XMP enabled you may run into stability issues. If you want to use 32GB RAM, we suggest you choose one kit of 4*8GB or 2*16GB RAM to use. Thanks!

I managed to run here in these settings.
3266 Cas 17 18 18 18 38, at least it ran with the 4 combs.

Memories 3733 running at 3266
MSi BIOS SUX

 

[lulafisi14f702d5]

MSI's support claims that different combs do not work. All kits are identical. All kits work with only 2 x16GB in 3733. What doesn't work is 4x16GB at anything above 3266. The memory is fine, I used the 4x16GB in an Asor Aorus and it worked. The problem is 100% on your board or in the BIOS that manages this. What's the excuse now?

Try this.

For what it's worth, I'm running 32gb Ballistix Elite DDR4-4000 CL18 in 4x8 sticks at 1:1:1 Ratio, I couldn't get it run boot with the XMP enabled before the December beta BIOS update though. So far it's running rock solid.

Guys,

1) your CPUs have been designed to work with memory speeds "up to 3200" MHz.
Here is a top CPU: https://www.amd.com/en/products/cpu/amd-ryzen-9-5900x
System Memory Specification : Up to 3200MHz
That means AMD does not guarantee stability with faster memory.

2) overclocking = gambling
What might work (stable) for you does not mean will work (stable) for everyone

3) more memory you have, lower speed you'll get.
So you cannot compare 4 x 8GB with 4 x 16GB.

 

[dom.l.curti155402df]

Should've said I've running a 5600x in an X570 Tomahawk, maybe I just got lucky and I have a happy memory controller.

The biggest problem is that MSI itself does not put this so openly that it will not work with 4 memory sticks.
Because if the CPU was limiting as the colleague said, it would not run with 2x16GB in 3733 as I already did. The problem is the motherboard's memory controller, it is difficult for MSI to accept this and even more difficult is to propose a BIOS that makes 4x16GB or 32Gb work.

MSI already answered that they don't work if they are different chips, I already showed them that they are the same. You already told me that it is processor limiting, I have already shown that it is not. The only thing they don't do is assume that their bios are terrible.

2 ) The problem is the motherboard's memory controller

1) Again: more memory you have, lower speed you'll get.
You cannot compare 2 x 16GB with 4 x 16GB.

2) The motherboard does NOT have any memory controller.
Everything is inside of your CPU.
That's why is called CPU IMC (Integrated Memory Controller).

Several BIOS update manufacturers have managed to make 4x16GB or 4x32GB work at speeds of 3600+: 3733, 4000 etc.

What MSI lacks is to be faster at it.

So in your opinion, your CPU is able to work with any amount of memory at any speed.
Sorry but you're wrong.

Let me think, I believe what you are telling me or in the other technical forums that say the opposite ??? I think I will trust the people who have tested and managed to make it work. But thanks for your opinion.

but considering what you said, then it is characterized with misleading advertising the statement that MSI makes on the website that its MB works at higher speeds on certain Ryzen processors including the 5800x.

Very easy to cherry pick and make generalizations. There's people out there running faster memory too on MSI.
Long story short....it's well known, especially for AMD systems, that more memory means slower speeds. We've seen it for 5 generations now (yes, they're actually at 5 generations....).
And it's true for almost any system, be it Intel or AMD. Intel seems to be much better at not needing to lower speeds, if I'm honest, but it still happens.
And nothing when it comes to memory is guaranteed. Even AMD doesn't guarantee those speeds. There's a reason for that.....they're be idiots to do it.
But just like you, most people don't get it. And will just randomly argue their points because "other people on other places say different" "some youtube video told me different"
If some youtube video told you that you'll live if you jump out of an airplane, would you believe that too?
Remus is well respected in this forum, for good reason. He's provided assistance many times, and has a great understanding of the memory subsystems.
