Mining-focused ATX board

The Biostar TB250-BTC PRO is an Intel B250 ATX motherboard built for cryptocurrency mining rigs. It accepts LGA 1151 processors from the Core i7, i5, i3, Pentium and Celeron families up to a 95 W TDP limit. The design centres on 12 graphics-card interconnections rather than general-purpose expansion.

One full x16 slot plus eleven x1 links

A single PCI Express 3.0 x16 slot sits alongside eleven PCI Express x1 3.0 slots for dense GPU deployment. Six of the x1 slots deviate from the ATX standard and require an extra connecting kit to mount cards. Memory tops out at 32 GB across two DDR4 slots running at 2400, 2133 or 1866 MT/s. Storage connects through six SATA 6Gb/s ports.

Replaces standard B250 boards when GPU density

Swapping a conventional B250 board for this model makes sense only when you need more than two or three graphics cards on one system. The eleven x1 lanes and the 95 W CPU ceiling define the practical upgrade point; beyond that the board runs out of CPU power headroom and standard-slot compatibility.

Questions about this item

Will my 8th-generation Intel processor fit this board?

No, the socket is LGA 1151 but the chipset does not support 8th-generation CPUs.

How many graphics cards can I attach at once?

One full-length PCI Express 3.0 x16 slot plus 11 PCI-E x1 3.0 slots; six of the x1 slots need an extra connecting kit for standard cards.

What memory speed should I buy for a 7th-generation Core i5?

DDR4 2400 is supported with 7th-generation processors; 2133 and 1866 also work.
