llama.cpp + CUDA Setup — What I Learned

System: Ubuntu 24.04, GTX 1650 Ti (4GB VRAM)

Hardware Limits

• 4GB VRAM fits Llama 3.2 3B (Q4_K_M) fully on GPU with 4K context
• 8K context = partial CPU offload (slower), 16K+ = mostly CPU
• TinyLlama 1.1B runs easily with full offload
• No tensor cores on GTX 1650 Ti -- warning is cosmetic
• 7B models don't fit at Q4 (4.5 GB), Q2 is degraded quality

Humans remember names like google.com better.

DNS (Domain Name System) is the phonebook of the internet — it translates names → IPs.
