No. Qwen3.5 122B-A10B (MoE) does not fit on RTX 5090 32GB: Q4_K_M needs 83.7 GB and 31.5 GB is usable.
Hardware: RTX 5090 32GB · Model: Qwen3.5 122B-A10B (MoE)
RTX 5090 32GB has 32 GB of VRAM and 1792 GB/s of memory bandwidth. The checker holds back 0.5 GB of VRAM for the driver and assumes 16 GB of system RAM, so fast memory usable by Ollama is 31.5 GB. Partial offload may also use 60% of that system RAM. Qwen3.5 122B-A10B (MoE) (125B, 10B active, Alibaba) at Q4_K_M is a 81 GB download and needs 83.7 GB with headroom for about 8k tokens.
