What motherboard for Ryzen 5900x workstation/homeserver

Hi Guys,

what motherboard would you recommend for workstation/homeserver with ryzen 5900x?
It will run few websites (so 24/7 operation, but nothing enterprise level obviously:) and I will use it as development “workstation” - programming C# mostly, sometimes compiling larger projects or running more intesive computations for hours/days. It will run Hyper-V with few VMs.

My requirements:

  1. good VRM and component quality - for stability and longevity, not going to overclock
  2. would like to have 3x nvme PCIe 4.0 disks, so PICe 4 is a must, 3x m.2 ports would be nice to have but I can use expansion card for that
  3. ability to boot without monitor (and ideally also without GPU but that is optional) I plan to connect remotely
  4. fast memory support, minimum 3600

Don’t want/need

  • RGB - box is in another room, I want computer, not christmas tree
  • Wifi - I will only use ethernet
  • Good audio - this will never play anything
  • I also dont need too many usb ports etc.

Basically I am looking for solid base functionallity without all the bells and whistles that gamers like but I dont need.

Hmm I wonder if Asrock will come out with a “RACK” series motherboard with x570 chipset. Right now they have the x470 but no pci 4.

Take a look at SuperMicro and Tyan, they have some workstation focused offerings.

Are you going to do anything in regards to pci-e passtrough?
And of course what is your budget?

Do you mean like these

Only availability I found when I looked a few weeks back was in the US so no good for me but maybe will work for you.

pie-e passthrough - possibly… it’s not main requirement, but certainly would be nice since I plan to use this for VMs as well…

budget ideally not much over 300 usd…

Hm Asrock Rack X570D4U looks nice… any word about Ryzen 5000 support?
But don’t know if I can get this in Europe…

So my candidates so far after watching some Youtube reviews and your recommendations are:

Asrock Taichi X570 - http://www.asrock.com/mb/AMD/X570%20Taichi/
Asus WS X570 ACE - https://www.asus.com/Motherboards-Components/Motherboards/All-series/Pro-WS-X570-ACE/
Asrock Rack X570D4U - https://www.asrockrack.com/general/productdetail.asp?Model=X570D4U#Specifications

I am also wondering if I could get away with some cheaper B550 board that has reasonably good VRM… haven’t looked into entry level boards much yet…

Heads up: If you are considering this board while hoping for IPMI-like remote interface then you should know it is not the real thing:

beta bios already supports them. (separate ‘beta zone’ download section)

edit: report from someone already running it with 5900x: Asrock X570d4u, x570d4u-2L2T discussion thread

Nice. Do we know something about fast memory support? I will need 64GB and was thinking about 3600 MHz…

EDIT: G.SKILL 32GB KIT DDR4 3600MHz CL16 Trident Z looks like a good candidate

AFAIK X570D4U has no XMP profiles - You will have to dial in the OC by hand so don’t expect much - this is not a gaming/OC board.
There isn’t much info about 5000 series CPUs on this boards so things may be better or worse, you could try PM-ing people who report to have this combo (https://forum.level1techs.com/t/asrock-x570d4u-x570d4u-2l2t-discussion-thread/)

B550 boards are not really ideal for pci-e passtrough in that regards.
Because if the current situation on the iommu groupings on most B550 boards.

  • Asus WS pro X570 Ace: has a very good vrm.
    Only downside of this board is that it is a bit down on sata ports.
    And the second m.2 slot only runs at 2x instead of 4x speeds i believe.
    But other then that it basically would be a good option.
    vrm details: ASP1405i (IR35201) in 6+2 phase mode with double the components per phase.
    Which means a 12+2 power stage design featuring IR3555 60A power stages.

  • Asrock X570 Taichi: Good board with a decent vrm.
    vrm details: pwm: ISL69147 6+1 phase mode doubled to 12+2 using ISL6617 doublers.
    Powerstages Vishay 50A Sic634 DRmos.

  • Gigabyte X570 Aorus Master: good board with a great vrm as well.
    But that is probably not really a board that you would be looking for.
    Because of the additional gaming related features it comes with.
    vrm details: pwm: Infineon XDPE132G5G in 12+2 phase mode.
    powerstages 50A IR3556.

Those Asrock Rack boards might be interesting as well.
But i have not really looked much into those yet.
So i can’t really help with providing much info on those atm.
