What this compatibility result does not claim

No speed estimate

AIPCFit does not invent tokens-per-second numbers.

No fake system RAM

This page does not assume how much RAM your full PC has, so partial offload is not ranked.

No universal context guarantee

Longer context and runtime settings can increase real memory pressure.
