AMD BC-250 MINING BOARD / LOCAL AI ACCELERATOR Unlocked 40/40 CUs • P3.00 BIOS • Vulkan Inference Verified Key Specifications & Features
- Unlocked Compute Units: Software core unlocker applied — full 40 / 40 CUs active and routed.
- BIOS Configuration: Local firmware readout reports P3.00.
- Validated: Fedora 43 with llama.cpp (Vulkan build) identifies AMD BC-250 (RADV GFX1013). Both 9B and 12B inference runs produced their expected responses.
- Validated: No CU faults were observed during inference tests.
Important Hardware & Shipping Notes
- CR2032 Battery: The CR2032 battery used in testing is not included. You will need to install your own battery upon arrival.
- Storage: The NVMe drive used in testing is not included with this listing.
Unlockable Core Status (40 / 40 CUs)
The software core unlocker has been applied and all 40 available Compute Units (CUs) are currently active and routed. The live dispatch table shows all WGP pairs enabled across all shader engines and shader handlers.
Testing & Validation Process
This unit underwent practical validation before packaging:
- BIOS reports version P3.00; a custom BIOS patch is not independently verifiable from the running system.
- Software core unlocker applied and verified via live CU manager.
- Validated on Fedora 43 using llama.cpp (Vulkan build) with 9B and 12B LLMs loaded for inference, producing the expected coherent responses.
*Note: Basic functionality and inference validation performed. No formal extended stress testing was performed.
