Single-socket server board
The ASRock Rack EC266D4U-2L2T is a Micro-ATX server motherboard built around the Intel C266 chipset and an LGA 1700 socket. It accepts one Intel Xeon E-2400 series processor or a Pentium Gold G7400/G7400T with a 95 W thermal envelope. Four DDR5 288-pin slots support ECC UDIMMs up to 128 GB at 4400 MT/s.
Builders needing one CPU and ECC memory
This board suits integrators assembling compact single-socket servers or workstations that require ECC memory and 10 GbE networking. It does not suit builds that need dual-socket scaling, more than four memory channels, or additional full-length PCIe slots beyond the single x16 and x4 connectors.
One PCIe 5.0 x16 slot from the CPU
The primary expansion slot delivers PCIe 5.0 x16 bandwidth directly from the processor, while a second slot provides PCIe 4.0 x4 and shares lanes with an OCuLink port. Four OCuLink connectors and one M.2 slot complete the high-speed I/O.

คำถามเกี่ยวกับสินค้านี้
Will the DDR5 ECC UDIMM modules need to be replaced when I exceed 128 GB?
The board supports a maximum of 128 GB across four slots, so any capacity increase beyond that would require a different motherboard.
Which expansion slot becomes unavailable first when I add a card to the PCIe 4.0 x4 slot?
Populating SLOT7 disables OCuLink4 because they share the same CPU lanes.
How much heat does the 95 W TDP processor generate during continuous operation?
The supported CPUs have a 95 W thermal design power, which determines the cooling capacity you must provide for sustained loads.
