Can I Run Command R+ (104B) on NVIDIA RTX 6000 Ada Generation?
Written by Jakub Rusinowski · Last updated July 21, 2026
Not at Q4_K_M — that needs 65.7 GB at 8K context and the NVIDIA RTX 6000 Ada Generation has 48 GB. Drop to Q3_K_M and it fits in 47.3 GB, with up to 8K of context.

Command R+ (104B) on the NVIDIA RTX 6000 Ada Generation: VRAM by quantization

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 48 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the NVIDIA RTX 6000 Ada Generation: 8K 65.7 GB ✗ · 32K 72.2 GB ✗ · 125K 97.1 GB ✗. Past 8K it no longer fits 48 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Quantize to Q3_K_M. That is the cheapest fix — it costs some quality but no money.
