EAX-R680BP
Series: EAX
The Avalue EAX-R680BP is a full-size ATX industrial motherboard built on the Intel R680E chipset for 12th/13th/14th and Series 2 Gen Intel Core i9/i7/i5/i3 processors (up to 125W TDP) on the LGA1700 socket. Four DDR5 4400MHz U-DIMM slots support up to 192GB with ECC (CPU-dependent), and onboard TPM 2.0 plus broad PCIe Gen5/Gen4 expansion make it a high-performance workstation and edge-server foundation. Expansion is extensive: dual PCIe x16 (one x16 Gen5 default or two x8 Gen5), dual PCIe x4 Gen4, additional PCIe Gen3 slots, and two M.2 NVMe Gen4x4 slots plus four SATA III ports. The EAX-R680BP drives triple display through dual DisplayPort 1.4a (up to 7680x4320 @ 60Hz) and HDMI 2.1b (4K @ 60Hz HDR), with quad Intel I226 2.5GbE networking and a 5.1-channel audio subsystem with a 2x6W amplifier, running Windows 11 and Linux.
