1U Rackmount AM4 Barebone Server
This new ASRock Rack barebone ships as a 1U rackmount chassis with a 300 W redundant power supply. It is built around the AMD X470 chipset and accepts a single AM4-socket Ryzen processor from the 3000, 2000 or first-generation families. No CPU or memory comes installed, so the integrator chooses both.
For single-socket general-purpose builds
The board suits integrators who need a compact server that can run ECC DDR4 UDIMMs up to 128 GB across four slots. It is not suited for workloads that require dual processors, registered DIMMs, or more than two M.2 devices. Builds needing ten-gigabit networking or additional PCIe x16 slots should look elsewhere.
Dual-channel ECC DDR4 to 128 GB
Four 288-pin slots support DDR4 at 3200, 2933, 2666, 2400 or 2133 MHz in dual-channel mode with ECC or non-ECC UDIMMs. This memory ceiling and ECC support are the decisive factors when matching the platform to reliability-focused workloads.

Questions about this item
Which AMD Ryzen processor generations can I install in the AM4 socket?
The AM4 socket accepts AMD Ryzen PRO 3000 and 2000 Series, Ryzen 3rd and 2nd Gen, plus Ryzen 2nd and 1st Gen with Radeon Vega Graphics.
Will my existing DDR4 ECC UDIMM modules work in the four 288-pin slots?
Yes, the board supports DDR4 3200, 2933, 2666, 2400 and 2133 MHz ECC and non-ECC UDIMM up to 128 GB in dual-channel mode.
How can I verify the IPMI interface is functioning after assembly?
Connect the dedicated Realtek RTL8211E GLAN port; the ASPEED AST2500 BMC with 16 MB video memory will present a web management console at its DHCP address.
