III. GMR and GMM Pairing Rules (Must Read)

GMM11 (4 Axes / 256KB) → GMR22 (2D) (2000G Standard)

GMM12 (6 Axes / 512KB) → GMR22 or GMR24 (2000G/3000G General)

GMM22 (8 Axes / 1MB) → Must be GMR24 (3D) (3000G High-End)

IV. Common Faults

No Display: CN1 Loosening, GMM Not Started, Backplane DC5V Abnormal

Flickering / Mosaic: GMR Chip Aging, Resolution Mismatch, GMM/GMR Version Incompatibility

Graphics Not Refreshed: CN1 Bus Fault, GMM Memory Insufficient, Program Too Large
