The cmpunlocker driver patch will reproducibly unlock the claimed 64GB HBM, BF16 performance, and PCIe functionality on NVIDIA CMP 170HX cards.

What is this?

Cmpunlocker is a GitHub-hosted Linux patch for NVIDIA’s CMP 170HX (GA100) mining card, described by its author as removing imposed throttling and restrictions to restore A100-class compute throughput and memory capacity. The supplied repository snippet targets nvidia-open 580.x, while the evidence title names driver 610.43.03; claims also vary between 64GB and 80GB, and the snippets do not independently verify reproducibility, BF16 performance, or PCIe Gen2 functionality. Treat the full unlock as a project claim pending benchmarks and replication.

Why it matters to Scott

The claimed unlock converges with Scott’s usable-mass-over-unusable-power position and could materially expand his gamepc local-inference substrate through unusually cheap high-VRAM BF16 hardware. It warrants evaluation because memory capacity, precision support, and PCIe limits directly affect his hardware-aware runtime policy, but the supplied evidence does not yet establish reproducibility.
