What this error means
Memory calculation error — incorrectly calculates available system memory is a Ollama failure pattern reported for developers trying to fix ollama failing to load large models due to incorrect available system memory calculation. Based on the imported evidence, treat this as a tool-specific troubleshooting page rather than a generic API error.
Why this happens
Ollama fails to load qwen3.6:35b-a3b with memory error despite sufficient RAM. The memory calculation logic appears incorrect or overly conservative. Affects developers with high-RAM machines trying to run large local models.
Common causes
- Ollama fails to load large models (e.g., qwen3.6:35b-a3b) with a memory error despite sufficient RAM being available. The system memory calculation is incorrect or overly conservative, preventing developers from using large models on machines that should support them.
- Ollama fails to load qwen3.6:35b-a3b with memory error despite sufficient RAM. The memory calculation logic appears incorrect or overly conservative. Affects developers with high-RAM machines trying to run large local models.
Quick fixes
- Confirm the exact error signature matches
Memory calculation error — incorrectly calculates available system memory. - Check the Ollama account, local tool state, and provider configuration involved in the failing workflow.
- Compare the failing environment with a known working setup, then change one configuration value at a time.
Platform/tool-specific checks
- Verify the command, editor, extension, or API client that produced the error.
- Compare local settings with CI, deployment, or editor-level settings when the error appears in only one environment.
- Avoid deleting credentials, local model data, or project settings until the failing scope is clear.
Step-by-step troubleshooting
- Capture the exact error message and the command, editor action, or request that triggered it.
- Check whether the failure is account/auth, quota/rate, model/provider, local runtime, or deployment configuration.
- Review the source evidence below and compare it with your environment.
- Apply one change at a time and rerun the smallest failing action.
- Keep the working fix documented for the team or deployment environment.
How to prevent it
- Keep provider/tool configuration documented.
- Record non-secret diagnostics such as tool version, provider name, model name, and command path.
- Add a lightweight check before CI or production workflows depend on the tool.

FAQ
What should I check first?
Start with the exact Memory calculation error — incorrectly calculates available system memory text and the smallest action that reproduces it.
Can I ignore this error?
No. Treat it as a failed Ollama workflow until the root cause is understood.
Is this guaranteed to have one fix?
No. The imported evidence supports the troubleshooting path above, but tool behavior can vary by account, plan, version, provider, and local configuration.
How do I know the fix worked?
Rerun the same command, editor action, or request. The fix is working when that action completes without Memory calculation error — incorrectly calculates available system memory.
