Can I Run OLMo 2 13B Instruct on NVIDIA GeForce RTX 3070?
Written by Jakub Rusinowski · Last updated July 12, 2026
No. OLMo 2 13B Instruct needs 15.8 GB at 8K context (8.3 GB weights + 7.5 GB KV cache/overhead) at Q4_K_M and the NVIDIA GeForce RTX 3070 has only 8 GB. No quantization we publish closes a gap that size.

Assumes an 8K-token context with an f16 KV cache. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 8 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
What to do next
Either step down to a smaller size in this family, or move to a NVIDIA GeForce RTX 4090 Laptop GPU (16 GB), the card with the least memory we track that holds it.
