Which motherboard you recommend for Ryzen 5900x 12core ?

[PSP.]

Hello guys,
I have PC since 2017 , Ryzen 1600 and  Nvidia 1060 6gb , Motherboard Asus prime B350M-A , 16gb ram 3000mhz kit . using Noctua NH-U12S chromax black cpu cooler ( I purchased this year )

with this cooler I'm able to OC 1600 @3.90 benchmark prime95 max temp 72c
worse part here I think motherboard

recently I start using VM Linux 2core ubuntu , and want new VM for another Distro 2core 
and sometimes while running VM  I use photoshop 2core still less for jops and Browsering and editing photo or video

Gamer + Video and photo edit by Adobe + Running VM most times 
Dual monitor 1080p 144hz and 60hz

this much to explain what I have and sorry

 

Note : 
Nvidia 3060 on the way , Want buy CPU 5900x + Motherboard

I'm using  power supply 1200w platinium my uncle gift me this PSU
I have no Idea about Vram and how to know best motherboard 

1- I not care about RGB
2- Using NVME 

3- PCIE Wifi card on the way with 3060

4- another 16gb3000mhz kit also on the way . total memory i will have 32gb 

 

Help me choose I don't want to regret

Sounds like a job for the motherboard tierlist in the motherboards section

I recommend the Strix B550-F. It’s good, it’s cheapish.. it’s stable as a table. Check the qvl of each board you look at to make sure your ram will work properly. It’s no fun building a frustration box. 

[trag1c]

I have a 5900X paired with a ASUS X570 Strix F (might be E can't remember now) and it works well enough.

What's your budget for a board, and what's your location and currency?

I'm watching QVL have some Hynix or Samsung , and my Ram corsair CMK16GX4M2B3000C15W

QVL Gigabyte: X570 Aorus :
I don't know , Mean both supported ?
My Rams now 16gb ver 6.30

You might have some problems pairing them up. The last time I tried to mix Corsair DS sticks with Corsair SS sticks I had nothing but problems.

The Strix F and Strix A are the same, it's just the Strix A is listed for cheaper on the US PCPP for some reason, same goes for the Tomahawk and the Gaming Edge WiFi, they're essentially the same board, it's just one has WiFi and the other does not.

All of these boards are good and will handle the 5900X with ease. 

The main difference between X570 and B550 is that on X570, both the lanes that are wired to the CPU and to the Chipset are PCIE Gen 4, while on B550, the lanes that are wired to the CPU are Gen 4, but the lanes that are wired to the Chipset are Gen 3, unless you know you need the extra Gen 4 lanes that X570 offers, B550, as a Chipset, is just as good. 

 

Do keep in mind as well that you may need to update the BIOS if the board you bought was a made before Zen 3, and shipped with an older BIOS that did not support the AGESA code for Zen 3 CPUs (So the 5900X in this case), all of these boards have BIOS flashback functionality though, meaning you could update the BIOS without needing a CPU installed if needed.

QVLs don't mean much of anything, it's just kits that the board manufacturer tested with that specific board and made sure it works but it doesn't mean other kits that may not be listed on there wont work, they should work just fine, worst case you'll need to do some tweaking to get them to run at the advertised speed but that's about it. 

As for mixing RAM up, since you'll be using a 3000MT/s kit with a 3600 one, both will run at the lowest speed, so 3000 MT/s (Assuming that's what you're going to do), plus they're techincally not guaranteed to run stably together.

If you don't need the x570 PCIe layout go B550. B550 is newer and has more kinks ironed out. The decent B550 boards will out OC most x570 boards because of the newer memory trace layout.

 

Getting mixed ram kits to work at decent speed for Zen3 will likely be an issue, or with some luck it'll work 0 problems. I'd highly recommend selling the old kit and getting a new 32GB kit. Since you already have 16GB on the way it would depend how easily I could return/swap them for a 32GB kit. Since you don't have a MB yet your still waiting on the board anyhow.

 

A lot of interesting stuff mentioned in here.

Thank you so much , I know Ram better same kit or need timing , Purchased same kit
you said what I want to read thanks 
but still have 1 question 
why MSI MEG B550 around 300$ and other less around 200$ and good bords
why 300$ price? If you know could you tell me why this board around 300$ ?
I thought 300$+ for x570 boards

I'm Really thinking to sell kit and buy 32gb kit x2 16gb , and better timing
but when I pick motherbaord 
Thanks for info

That’s fine if you know what you are doing and are prepared to tune. But if you aren’t familiar with diagnosing hardware problems it’s best to be safe then sorry. If you are new to the hobby, you explained the qvl process perfectly in the first part of the quote, that is important if you are new and want a problem free experience.

It varies a bit. Depends on what cpu you have. It’s sort of exceptional for it to have much value.  For 5xxx not much.

I'm watching links
1- more USB
2- dual NVME
don't know about Vram but watching reviews about GIGABYTE B550 AORUS PRO V2

Have 10 USB ( x1 Bios )
and have dual Nvme , 
Do you confirm this board good for Ryzen 5900x ?

I own neither the board nor the cpu so I can’t either way.  I can say that sounds like a lot of USB.  One of the obnoxious things about the way chipsets work though is they’re a way of assigning pcie lanes and there are only so many to go around.  The result is that some m.2 slots turn off various sthings when they are filled.  Usually it’s sata ports but if you’re counting on all ten of those USB ports it might do to make sure.

 

what I remember about the b550 chipset:

Spoiler

B550 connects both ahead of the chipset and behind it.  That’s how they get Pcie 4 and pcie 3 functioning on the same machine. All pcie4 connections are ahead of the chipset directly to the cpu. My memory is with b550 this is only the top slot, the apu if there is one, and one m.2 slot generally.  All 3.0 only are behind it connecting to the chipset along with all the USB and most other I/o. The chipset only as iirc 4 Pcie4 lanes connecting to the cpu, so anything connecting to the chipset has to share that bandwidth with whatever else is sending data to the cpu at that time.  X570 works slightly differently being a different chipset, and having pcie 4.0 all the way down, but not very differently.

I own neither the board nor the cpu so I can’t either way.  I can say that sounds like a lot of USB.  One of the obnoxious things about the way chipsets work though is they’re a way of assigning pcie lanes and there are only so many to go around.  The result is that some m.2 slots turn off various sthings when they are filled.  Usually it’s sata ports but if you’re counting on all ten of those USB ports it might do to make sure.

 

what I remember about the b550 chipset:

  Hide contents

B550 connects both ahead of the chipset and behind it.  That’s how they get Pcie 4 and pcie 3 functioning on the same machine. All pcie4 connections are ahead of the chipset directly to the cpu. My memory is with b550 this is only the top slot, the apu if there is one, and one m.2 slot generally.  All 3.0 only are behind it connecting to the chipset along with all the USB and most other I/o. The chipset only as iirc 4 Pcie4 lanes connecting to the cpu, so anything connecting to the chipset has to share that bandwidth with whatever else is sending data to the cpu at that time.  X570 works slightly differently being a different chipset, and having pcie 4.0 all the way down, but not very differently. 

 

Avoid much USB
Link my one of best motherboard B550 , Dual NVME for 5900x I will buy item now

why MSI MEG B550 around 300$ and other less around 200$ and good bords
why 300$ price? If you know could you tell me why this board around 300$ ?

The board is generally just a technically better board, all of them are more than sufficient, but the Unify is technically better, for a casual user, it wont actually matter in practice though.

I thought 300$+ for x570 boards 

Chipset does not determine product segmentation or price to a certain degree, there are some high end and low X570 boards, same with B550.

Could you link me best of B550 and best VRM have Dual NVME ?
I ready to order just waiting link of best B 550

All of the boards I linked above have more than good enough VRM and dual NVME Slots. 

Techincally speaking, the B550 Unify has the best VRM out of all of them, running an XDPE132G5C and 16 ISL99390 SPS, but that wont really matter for a more casual user, all of the boards above will perform very similarly.
