An open-source Linux kernel module removes Nvidia’s software divider for FP16 and BF16 tensor operations on GeForce 30-series cards. The project passed 5,000 GitHub stars in a few days.

It loads before Nvidia’s driver, sets full speed in registers normally off-limits, then hands the card back to the stock driver. No driver patch after updates or BIOS flash is needed. On a 3090 Ti, BF16 rose from 87.5 to 157.4 TFLOPS at 450 W.

Real workloads see a smaller gain. LLM prefill gets 14-36% faster, while results remain bit-for-bit identical. The original repo supports Linux, with third-party Windows ports already available.
