  • Delivers 8-channel audio through Realtek ALC887 and gigabit LAN via Realtek RTL8111H

Mining-focused LGA 1151 platform

The Biostar TB250-BTC is an ATX motherboard built around the Intel B250 chipset for socket LGA 1151 processors. It accepts Core i7, i5, i3, Pentium and Celeron CPUs from the 6th and 7th generations. Eight-generation chips are not supported. The layout provides one full-length PCI Express 3.0 x16 slot plus five PCI Express x1 3.0 slots that can be switched to 1.0 speed in the BIOS for mining stability.

Six expansion slots for multi-GPU rigs

This board suits builders who need to run several graphics cards from a single CPU for cryptocurrency mining or compute workloads. The x1 slots are spaced to accommodate riser cables. Users who require more than two memory modules, integrated Wi-Fi, or support for newer Intel processors should choose a different platform. The single x16 link and dual-channel memory limit also make it a poor fit for modern gaming builds.

Dual-channel DDR4 with two DIMM slots

Memory support tops out at DDR4 2400 when a 7th-generation Core CPU is installed; 6th-generation processors run at 2133 or 1866. Only two 288-pin slots are provided, capping total system memory at 32 GB. If your workload demands four slots or higher memory bandwidth, this motherboard will not meet the requirement.

Points forts

  • Supports up to six graphics cards via five PCIe x1 slots and one PCIe x16 slot
  • Runs seventh-generation Core i7, i5, i3, Pentium or Celeron processors on LGA 1151 socket
  • Accepts DDR4 memory at 2400, 2133 or 1866 MT/s across two 288-pin slots
  • Provides six SATA 6 Gb/s ports plus one M.2 Key M connector for 2242, 2260 or 2280 drives
  • Delivers 8-channel audio through Realtek ALC887 and gigabit LAN via Realtek RTL8111H

Questions sur cet article

What PCIe standard does the M.2 Key M 32Gb/s connector use?

The M.2 Key M connector supports SATA 6Gb/s and PCIe storage at 32Gb/s bandwidth.

What are the physical dimensions and mounting requirements for this ATX motherboard?

The board uses standard ATX form factor with 288-pin DDR4 memory slots and requires an ATX-compatible case with matching standoff positions.

How do you configure the PCI-E x1 slots for mining and what BIOS change is commonly missed?

Enter BIOS and change the five PCI-E x1 3.0 slots to PCI-E 1.0 mode, which is the step many builders overlook when setting up multiple GPUs.
