Server Motherboard for Xeon W Workstations
This ASRock Rack board uses the LGA 4677 socket and Intel W790 chipset to support a single Xeon W-2400, W-2500, W-3400 or W-3500 series processor. Eight DDR5 288-pin slots accept registered memory up to 2 TB at DDR5 4800 speed. It targets builders who need high core counts and large memory capacity in a Deep Micro-ATX form factor.
Practical Limits of PCIe 5.0 and OCuLink
Four full-length PCIe 5.0 x16 slots connect directly to the CPU for maximum bandwidth with accelerators or GPUs. Two OCuLink connectors run at PCIe 4.0 x4 from the chipset; one can alternatively carry four SATA 6 Gb/s ports. The single M.2 M-key slot also uses a PCIe 4.0 x4 chipset lane and fits 2280 modules.
Dual 10GbE Decides Network Fit
Two RJ45 ports driven by the Broadcom BCM57416 provide 10 Gbps Ethernet. A second Intel i226 controller adds 2.5 Gbps and a third Intel i210 adds Gigabit for management. If the deployment does not require dual 10 GbE, the board still offers the PCIe 5.0 slots and memory capacity for compute-heavy tasks.

Întrebări despre acest articol
Should I pick the W790D8UD-1L1N2T/BCM with 8 DDR5 slots and 2 TB max or a board with fewer slots?
This board provides 8 DDR5 288-pin slots and supports up to 2 TB of registered DDR5 4800 memory, so choose it when you need maximum capacity and 2 DIMMs per channel.
What does the 10 GbE Broadcom BCM57416 controller deliver in a live server?
The dual 10 GbE ports from the Broadcom BCM57416 provide two 10 Gbps RJ45 links for high-throughput networking alongside a 2.5 GbE Intel i226 port and a 1 GbE Intel i210 port.
How do the PCIe 5.0 x16 slots and OCuLink connectors limit add-in cards?
Four PCIe 5.0 x16 slots connect directly to the CPU, while two OCuLink connectors from the PCH each provide PCIe 4.0 x4 or four SATA 6 Gb/s lanes for storage expansion.
