NVIDIA Sells You Half a GPU: Inside the FP32 Accumulation Unlock
The gpu-unlock kernel modules lift NVIDIA’s half-rate FP32 accumulation cap on RTX 20, 30 and 40 series cards. The instruction rate doubles, the real-world gain is 10 to 20 percent, and the 4090 is the last card this works on. How the exploit works, what the benchmarks actually say, and why Blackwell closes the door.
