GPU-Unlock provides a Linux kernel module that changes Ampere GeForce firmware state before the driver loads, enabling a higher FP16/BF16 tensor-core issue rate. The author reports 14%–36% faster LLM prefill with little decode change. It requires rebooting and modifies an unsupported low-level path.

Availability: GPL-licensed source repository; manual kernel integration and reboot required
What this means for you
This may improve batching and prefill economics on older consumer GPUs, but evidence is author-reported. Kernel- and firmware-level changes carry higher stability, warranty and rollback risk than ordinary inference tuning.
