Cryptocurrency mining continues to evolve, with hardware manufacturers tailoring specialized components to meet the demands of high-efficiency mining rigs. Biostar, a well-known name in the motherboard and graphics card space, has stepped up its game with two new mining-focused products: the TB250-BTC PRO motherboard and the VA47D5RV42 (Mining) GPU based on AMD’s Radeon RX 470D architecture. These releases reflect a growing trend of purpose-built hardware designed for stability, scalability, and performance in continuous mining operations.
TB250-BTC PRO: A Scalable Mining Motherboard Built for Power
At the heart of Biostar’s latest offering is the TB250-BTC PRO, an upgraded version of the original TB250-BTC unveiled at Computex 2017. This ATX-form-factor motherboard is engineered specifically for multi-GPU mining setups, supporting up to 12 graphics cards simultaneously via 12 native PCIe 3.0 x1 slots—plus one full-sized PCIe 3.0 x16 slot, typically used for the primary GPU or system expansion.

What sets the TB250-BTC PRO apart from competitors like ASRock’s H110 Pro BTC+ is its use of native PCIe 3.0 lanes across all expansion slots. While some rival boards rely on PCIe 1.0 or 2.0 lanes routed through chipset limitations, Biostar leverages the Intel B250 chipset to deliver full PCIe 3.0 bandwidth, enhancing communication stability between GPUs and the CPU. This design choice improves compatibility and reduces potential bottlenecks—critical factors in maintaining hash rate consistency over long mining cycles.
The board supports Intel LGA 1151 processors, including Core i3/i5/i7, Pentium, and Celeron models with a maximum 95W TDP. It features dual DDR4 DIMM slots for system memory, six SATA III ports for storage, and a single M.2 slot capable of handling both PCIe 3.0 x4 and SATA-based NVMe drives—an upgrade over the base model that lacked M.2 support.
For power delivery, Biostar includes two Molex connectors and two PCIe 4-pin 12V power inputs directly on the motherboard, ensuring stable voltage distribution when running multiple high-draw GPUs through riser cables. The physical layout of the PCIe slots is also optimized to prevent short circuits, with staggered spacing accommodating USB-to-PCIe risers commonly used in mining farms.
Key Specifications:
- Chipset: Intel B250
- Expansion Slots: 1× PCIe x16 3.0, 11× PCIe x1 3.0
- Memory Support: 2× DDR4 DIMM (up to 32GB)
- Storage: 6× SATA III + 1× M.2 (PCIe/SATA)
- Networking: Realtek RTL8111H Gigabit Ethernet
- Audio: Realtek ALC887 8-channel HD audio
- I/O Panel: 4× USB 3.0, 4× USB 2.0 (including high-current 5V/1.5A ports), DVI-D, RJ-45, audio jacks
Biostar claims that upgrading from two standard TB250-BTC motherboards (each supporting six GPUs) to a single TB250-BTC PRO can save users around $200 in initial setup costs, factoring in reduced motherboard count, fewer CPUs needed, and lower power supply complexity.
Additionally, the board supports what Biostar calls “Hybrid Mining” technology, allowing users to run both AMD and NVIDIA GPUs within the same system. While this functionality isn’t unique—most modern mining software like HiveOS and RaveOS already support mixed GPU farms—the branding emphasizes plug-and-play readiness for diverse configurations.
VA47D5RV42 Mining GPU: Bringing the RX 470D to Global Attention
While motherboards form the backbone of any mining rig, GPUs remain the workhorses driving computational power. Biostar’s entry into mining-specific graphics cards comes in the form of the VA47D5RV42 (Mining), built around AMD’s lesser-known Radeon RX 470D GPU.
Originally launched quietly in China without global fanfare, the RX 470D is a trimmed-down variant of the Polaris 10 architecture. It features 1792 stream processors, compared to the standard RX 470’s 2048, making it slightly less powerful but potentially more efficient under sustained workloads—a key consideration for miners focused on cost-per-hash rather than peak performance.
The VA47D5RV42 is equipped with a custom cooling solution and ships with factory-tuned memory clocks, running its 4GB GDDR5 VRAM at 7000 MHz—a boost that may enhance memory bandwidth during Ethereum-style DAG computations.
Despite being labeled as a “mining” card, the VA47D5RV42 retains standard display outputs: 1× DVI, 3× DisplayPort, and 1× HDMI—unlike ASUS’s dedicated mining GPUs which omit video outputs entirely. This suggests Biostar may be targeting users who want flexibility between mining and occasional gaming or compute tasks.
However, availability remains unclear. The card appears only on Biostar’s U.S. product page without official pricing or retail distribution announcements. No listings exist on major e-commerce platforms like Newegg or Amazon, indicating it may be intended for bulk sales or regional markets rather than consumer retail.
That said, its presence on U.S.-facing pages hints at a potential semi-official expansion beyond China—a surprising move given AMD’s initial positioning of the RX 470D as a China-exclusive product tailored to local market demands.
Frequently Asked Questions (FAQ)
Q: Is the TB250-BTC PRO compatible with Ryzen CPUs?
A: No. The TB250-BTC PRO uses the Intel B250 chipset and supports only LGA 1151 socket CPUs such as Intel Core i3/i5/i7, Pentium, and Celeron series processors.
Q: Can I run both AMD and NVIDIA GPUs on the TB250-BTC PRO?
A: Yes. Thanks to Biostar’s “Hybrid Mining” support and modern mining OS compatibility, you can mix AMD and NVIDIA cards on this motherboard using software like NBMiner or T-Rex.
Q: Why are native PCIe 3.0 slots important for mining?
A: Native lanes provide dedicated bandwidth from the CPU, reducing latency and improving communication reliability with each GPU—critical for maintaining consistent hash rates and avoiding crashes.
Q: Is the VA47D5RV42 a true mining-specific GPU?
A: Partially. While marketed as a mining card and based on a China-exclusive GPU, it still includes full display outputs and hasn’t been released through traditional retail channels.
Q: Does Biostar offer warranty support for these mining products?
A: Official documentation does not specify extended warranties for mining use, so standard return policies likely apply. Always verify with authorized resellers before purchase.
