Yes, with partial offload (slower). Flint 40B-A2.5B (MoE) on RTX 4090 24GB at NVFP4 uses system RAM (24.6 GB needed, 23.5 GB usable), about 128 tok/s (estimate).
Hardware: RTX 4090 24GB · Model: Flint 40B-A2.5B (MoE)
RTX 4090 24GB has 24 GB of VRAM and 1008 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 23.5 GB. Partial offload may also use 60% of that system RAM. Flint 40B-A2.5B (MoE) (39.8B, 2.5B active, Recursive) at NVFP4 is a 23 GB download and needs 24.6 GB with headroom for about 8k tokens.
