Dual-node density in 1U
The ASRock Rack 1U2N2G-AM5/2T fits two independent server nodes into a single 1U rackmount chassis. Each node accepts one AM5 socket processor from the AMD EPYC 4005 or 4004 series, or from the Ryzen 9000, 8000 and 7000 families, with a thermal ceiling of 120 W. The platform targets general-purpose workloads that benefit from high compute density.
PCIe 5.0 expansion and DDR5 5600 memory limits
Each node provides one full-height full-length dual-slot PCIe 5.0 x16 slot that can bifurcate into two single-slot x8 links, and one M-key M.2 slot wired for PCIe 4.0 x4 in the 2280 form factor. Memory capacity stops at 192 GB across four 288-pin DDR5 5600 UDIMM slots with ECC support, so configurations needing more memory or faster DRAM speeds cannot be satisfied.
Redundant CRPS power and front I/O
A 1+1 CRPS power supply delivers 1600 W at 200–240 V input or 1000 W at 100–127 V, with 80 PLUS Platinum efficiency. Front access includes two USB 3.2 Gen 1 ports and a VGA connector per node, while dual RJ45 ports driven by a Broadcom BCM57416 controller provide 10 Gigabit Ethernet. Eight hot-swap PWM fans handle cooling, and IPMI remote management is built in.

Questions about this item
Should I pick an EPYC 4005/4004 or a Ryzen 9000/8000/7000 CPU for this AM5 barebone?
Choose EPYC 4005/4004 for server-grade features and validated ECC support, or Ryzen 9000/8000/7000 for higher clock speeds and core counts in single-threaded workloads; both fit the LGA 1718 socket and stay within the 120 W TDP limit.
What does the 120 W TDP ceiling mean for CPU choice in a 1U dual-node chassis?
It limits you to processors rated at or below 120 W; any EPYC 4005/4004 or compatible Ryzen 9000/8000/7000 part within that envelope will run without throttling, provided the 1+1 CRPS supply delivers 1600 W at 200-240 V input.
How does the PCIe 5.0 x16 slot perform when split into two x8 links for GPU or accelerator cards?
The slot operates as one full-height full-length dual-slot PCIe 5.0 x16 or bifurcates to two single-slot x8 links, each delivering 5.0 GT/s per lane directly from the CPU for low-latency accelerator or storage add-in cards.
