ASUS PRO WS X570-ACE, LGA AM4, ATX, 128GB DDR4 ECC, 4 DIMM, GB LAN, DUAL M.2

I managed to get mine for a good price, but even when pricier this board is amazing. True x8x8x8 on AM4 is not a common thing, but ASUS pulled it off. If you max out all PCIe connections it has to offer, the X570-ACE can actually support up to 34 lanes! (One should note however that the U.2 bus is strictly meant for storage only. Other devices will not be recognised.) True ECC support is invaluable too. I do wish a better in-built NIC was used, but with this amount of PCIe connectivity, that isn't the end of the world. This board is mostly exceptional for those who need the features it provides.

Actually works as specified and doesn’t crash. This is the third MB I purchase to build a PC with Ryzen 9 CPU and Radeon 5700 GPU. The other two from the same manufacturer fail to find the network although could find the internet. Also the crashed constantly. The longest uptime was about ten minutes. Two such problem MBs indicates a problem with the architecture or bios.The Asus MB work straight of and has caused no problems enabling to concentrate on my work and not the equipment.

Impressive performance and stability. One of the best motherboards out there. The only problem is that it doesn't have load of USB slots and sata connectors.
