Description
🧰 Overview – BIOSTAR TB250-BTC
Model: Biostar TB250-BTC
Chipset: Intel B250
CPU Socket: Intel LGA 1151 (Socket H4) — for Intel 6th & 7th-Gen CPUs (e.g., Core i7/i5/i3, Pentium, Celeron)
Form Factor: ATX (~29.5 × 21 cm)
This board is designed with multiple PCI-Express slots and extra power connectors, making it a popular choice for GPU mining rigs rather than typical gaming/desktop builds.
🧠 CPU & Memory
CPU Support:
✔ 6th & 7th-Gen Intel Core / Pentium / Celeron processors on LGA1151
⚠ Not compatible with newer Intel CPUs (8th Gen and above)
Memory:
2 × DDR4 DIMM slots (dual-channel)
Supports DDR4-2400/2133/1866 MHz
Up to 32 GB total DDR4
📊 Expansion & PCIe Slots
This is one of the board’s standout points — it has numerous PCI-Express slots for multi-GPU use:
1 × PCIe 3.0 x16 (for main GPU or primary device)
5 × (or more) PCIe 3.0 x1 slots — used with risers for additional GPUs (often seen in mining rigs)
Many miners configure BIOS and slot connections for stability when connecting several GPUs.
💾 Storage & Connectivity
Storage:
6 × SATA III (6 Gb/s) ports for SSDs/HDDs
1 × M.2 (Key M, 32 Gb/s) slot supporting NVMe PCIe and SATA SSDs
Back Panel I/O:
USB 3.0 and USB 2.0 ports
DVI-D (with supported CPUs)
Gigabit LAN (Realtek)
Audio jacks
🔌 Networking & Audio
LAN: Realtek RTL8111H Gigabit Ethernet
Audio: Realtek ALC887 7.1-channel high-definition audio
⚡ Mining-Focused Features
This board is optimized for cryptocurrency mining setups:
✅ Multiple PCIe slots for GPU risers
✅ Extra board power connectors (Molex/SATA power) for added stability under load
✅ BIOS options to set PCIe speed to Gen 1 for better mining stability
📌 Compatibility Summary
Component Support
CPU Socket Intel LGA1151 (6th/7th Gen)
Chipset Intel B250
Memory DDR4 up to 32 GB
PCIe 1 × x16 + 5 × x1 slots (mining-oriented)
Storage 6 × SATA III + 1 × M.2
🧠 Important Notes
Because it uses the Intel B250 chipset and LGA1151 socket, it cannot be paired with AMD CPUs or newer Intel sockets like LGA1200/LGA1700.
Some mined rigs use BIOS tweaks (Gen 1 mode) and risers for stability — that’s fine for mining but not how typical consumer boards operate.
