Running DeepSeek V4 Flash 4-bit on Low-End Hardware: A Hardcore Experiment
Similar_Can_3143 · reddit · 2026-08-23
The author shares experiments running DeepSeek V4 Flash 4-bit quantization on constrained hardware (2x 3090+3060, 128GB RAM). By modifying llama.cpp logic to eliminate redundant caching between RAM and VRAM, and adopting a two-stage strategy (lower quant model for prompt processing + original model for generation), they achieved 20+ tgs generation speed and nearly 200 t/s prompt processing speed.
