MiniMax-H3 Low-VRAM Setup: Save 10GB+ VRAM and Eliminate Swapping
Annual_Mess_1839 · reddit · 2026-08-10
A developer shared an optimized configuration combo for MiniMax-H3 that saves over 10GB of VRAM, completely resolving shared GPU memory usage and swapping issues even on an RTX 5090.
Optimized Components & VRAM Footprint:
- prunedw4a8mixed: 11.6GB
- qwen3vl4bint4convrot: 2.6GB
- videovaeint8convrot: 2.95GB
- audiovaebf16: 295MB
While this setup doesn't increase generation speed, it eliminates random slowdowns, latency spikes, and system memory pressure. The author recommends using this lightweight setup for prompt testing and quick experiments, then switching back to higher precision models for final renders.
