The Express-BD74 is a COM Express COM.0 R3.0 Basic Size Type 7 module supporting the 64-bit Intel Xeon processor D (formerly «Broadwell-DE») system-on-chip (SoC) with up to 4 SO-DIMMs to boost system performance. The Express-BD74 is specifically designed for customers who need excellent computing performance with balanced power consumption and multiple 10G Ethernet connectivity in a long product life solution.
The Express-BD74 features Intel Virtualization Technology (including VT-x, VT-d, EPT), Intel Hyper-Threading Technology (up to 16 cores, 32 threads), Intel Trusted Execution Technology, Intel AES-NI Technology, and 4 SO-DIMMs to provide a maximum of 128GB DDR4 ECC (or non-ECC) memory capacity and dual-channel memory design at 1866/2133/2400 MHz (dependent on SoC SKU) for excellent overall performance.
An integrated Intel 10G Ethernet controller supports two 10GBASE-KR interfaces, relevant sideband signals and NC-SI. The Express-BD74 is designed to serve customers with optimized computing capability per watt and high speed connectivity requirements who want to outsource the custom core logic of their systems for reduced development time.
Input/output features include 24 PCIe Gen3 lanes, up to 8 PCIe Gen2 lanes, a single onboard Gigabit Ethernet port, USB 3.0/2.0 ports, and SATA 6 Gb/s ports. Support is provided for SMBus and I2C. The module is equipped with SPI AMI EFI BIOS with CMOS backup, supporting embedded features such as remote console, hardware monitor, and watchdog timer.
