RTX 3090 Ti achieves high LLM speeds with custom GPU unlock

By PulseAugur Editorial · [1 sources] ·

A user on Reddit's r/LocalLLaMA subreddit shared their setup for achieving high performance with local large language models on consumer hardware. By utilizing a single RTX 3090 Ti GPU and 128GB of RAM, they were able to run DeepSeek-V4.1-Flash-1017 at approximately 35 tokens per second and Qwen3.8-Flash-Next at around 130-140 tokens per second. The user detailed a specific method involving a custom kernel module called `gpu-unlock` to bypass artificial firmware throttles on NVIDIA consumer GPUs, enabling faster matrix instruction issue rates.
