Server motherboard with four 1 GbE ports
The ASRock Rack EC266D4-4L is an ATX server motherboard built around the Intel C266 chipset and the LGA 1700 socket. It supports a single Intel Xeon E-2400 series processor or an Intel Pentium Gold G7400/G7400T with a thermal design power of 95 W. The board provides four DDR5 288-pin slots running at 4400 MT/s with ECC, up to 128 GB total.
Builders needing four copper 1 GbE links
This board suits systems that require four RJ45 ports driven by Intel I210 controllers and two M.2 connectors each wired for PCIe 4.0 x4. It also delivers one PCIe 5.0 x16 slot, one PCIe 5.0 x8 slot and two PCIe 4.0 x4 slots for add-in cards. Buyers who need 10 GbE or faster onboard networking should consider other platforms.
The shared-lane arrangement between the two top
SLOT6 operates at PCIe 5.0 x16 when SLOT4 is empty, but drops to x8 as soon as SLOT4 is populated. This single constraint decides whether the motherboard can host two full-bandwidth expansion cards simultaneously.
