Yes, with partial offload (slower). Nemotron 3.5 Lightning 30B-A3B (MoE) on RX 7900 XTX 24GB at Q4_K_M uses system RAM (26.4 GB needed, 23.5 GB usable), about 49 tok/s (estimate).
Hardware: RX 7900 XTX 24GB · Model: Nemotron 3.5 Lightning 30B-A3B (MoE)
RX 7900 XTX 24GB has 24 GB of VRAM and 960 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. Nemotron 3.5 Lightning 30B-A3B (MoE) (31.6B, 3B active, NVIDIA) at Q4_K_M is a 25 GB download and needs 26.4 GB with headroom for about 8k tokens.
