GeForce RTX 3090 24GB (desktop) for Local LLMs: VRAM and Model Fit
24 GB GDDR6X is discrete VRAM: 25,769,803,776 bytes (24.00 GiB). The default system reserve is 2,147,483,648 bytes (2.00 GiB), and the net is 23,622,320,128 bytes (22.00 GiB).
GeForce RTX 3090 24GB (desktop): 24.00 GiB gross, default reserve 2.00 GiB, net calculator budget 22.00 GiB. Vendor-marketed GB for discrete GPU VRAM is treated as GiB (2^30 bytes), matching physical GDDR/HBM module organization. This is an explicit unit assumption.

Gross vs reserve vs net budget
- NVIDIAGeForce RTX 3090 24GB desktop · desktop-gpu
- Memory kinddiscrete-vram
- Marketed24 GB GDDR6X
- Gross25,769,803,776 bytes = 24.00 GiB
- Default reserve2,147,483,648 bytes = 2.00 GiB
- Net budget23,622,320,128 bytes = 22.00 GiB
The reserve is a configurable calculator assumption, not a measured desktop tax. Headless systems can lower it after measuring baseline board usage.
Catalog fit at 8,192 tokens
Each row is the same automatic pick as the calculator at 8,192 tokens: the highest precision at or above 3 bits per weight that fits. A file under that floor stays available for a manual choice and is not the automatic row. Concurrent sequences = 1, FP16 KV. Fit and software support are separate. Format compatibility is not a verified run.
