Can the GeForce RTX 3090 (used) run GLM-4.7-Flash?
Fits comfortably at Q4_K_M.
GLM-4.7-Flash is 30B parameters (MoE; all experts resident). At Q4_K_M the weights are about 16.8 GiB; with the 1.5 GiB runtime reserve that is 18.3 GiB against the card's 24GB, leaving about 5.7 GiB for context.
All three quants
24GB card| Quant | Weights | With reserve | Verdict | Headroom |
|---|---|---|---|---|
| Q4_K_Mthe everyday quant | 16.8 GiB | 18.3 GiB | Fits comfortably | 5.7 GiB |
| Q8_0near-lossless | 29.6 GiB | 31.1 GiB | Only with CPU offload | short 7.1 GiB |
| FP16full weights | 55.9 GiB | 57.4 GiB | Does not fit | short 33.4 GiB |
Verdict rules: fits comfortably when weights plus reserve sit within 85% of VRAM; tight when they fit with little left for context; CPU offload when they exceed VRAM by up to 2x (runs, slowly, with layers in system RAM); no beyond that. The KV cache per token depends on the model's architecture and is not modelled here.
