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.
