AsRock Rack X399D8A-2T ATX Server Motherboard AMD TR4 4094P AMD X399 Dual 10 GLAN

The motherboard is rock-stable and is working better than my ASUS Zenith Alpha in my home lab setup with Threadripper 2950x. BMC is great and you can access IPMC via the same RJ45 connector as you use for LAN, albeit on a different IP. Surprisingly, you can even overclock the processor and the RAM on this MB using AMD settings in the BIOS. Lots of great connectivity options are available, aside of three PCI x16 dedicated expension slots. The board is worth every penny. The only small negative is that X399 heatsink gets toasty, but that's expected on most server motherboards. Good air cooling does it well but I have to say even with Auto PWM fans (I use Noctua) it's mild if at all loud.

This board was the most unstable build I've done to date. 10 attempts with 2 different OS and 8 sticks of ram. Updated all drivers for everything and it kept coding and Bsod.

Only one of the motherboards had a manual, m2 screws or cables. Prevents us from proceeding with the build and quite annoying given a time constraint. More than happy to give a post-build review if the remaining parts are sent to fix this. Thanks for your help in advance!Cheers,Adam

Used this in a build that included the AMD 2920X, 64G of Kingston KSM26ED8/16ME ECC, one XPG 512G NVMe (ASX8200PNP-512GT-C), two StarTech Dual M.2 PCIe 3.0 NVMe adapters (PEX8M2E2), and four Sabrent Rocket Q 1TB NVMe (SB-RKTQ-1TB) drives with ZFS raidz1.Had zero issues with the board, basically powered up on the first try, installed Proxmox 6.2, then ZFS on the 4x1T NVMe drives, and spun up 16 LXC containers, and a couple VMs. The BMC is awesome, be sure to get the desktop app off asrockrack.com, which works well for me and supports Mac, Win10, and Linux.

Running a 2970WX in this board, and running 128GB ECC 2400mhz 24 HDD drives, 5 sas cards, dual nvme, onboard 10gb is extremely stable and fast. A++++ for a Server / Threadripper board.1 Star for tech support as a company like this... does not offer live chat, or telephone tech support. They should be ashamed.

I purchased this to build an AMD Ryzen Threadripper 2970WX 24-core server. The newer Threadrippers had just come out and were out of budget so we settled on this one. This motherboard is fantastic. It has IPMI which was a nice feature. I'm running dual NVMe M.2 Samsung EVO 970 drives in RAID 1. The system comes with 3 NICs: 2 10Gb ports (Intel X550) and 1 1Gb port. So far, I've installed 64 GB but will eventually go to 128 GB. Make sure you get RAM that has been vetted for this board. There is an onboard GPU which has basic functionality but on my board, there is some kind of interference as I've tried multiple VGA cables and monitors and there's an interference-like pattern on the screen. Not that important as this is being used as a server but something to note. I'm running Windows Server 2019 Essentials. Note that there are some exclamations in the device manager that cannot be cleared up as Asrock doesn't have drivers that will clear them up. Tech support admits that Server 2019 support isn't there yet. Performance has been rock solid and the system is extremely stable and fast. I haven't had a chance to get the 10Gb network in place yet but the 1Gb performance is quite good. Threadripper server class motherboards are few and far between. If you're used to HEDT motherboards or gaming motherboards, the lack of bells and whistles of this board will be shocking. However, those consumer boards don't have things like IPMI. If you're looking to use an older Threadripper with the X399 chipset in a server setting, this motherboard will work quite well for you.
