NVIDIA row-remap failure-flag conditions (RMA requires Field Diagnostic validation): a further uncorrectable-error remap on a bank already holding eight remapped rows, a duplicate-row remap, or 512 total remappings
8 rows / 512 remapsobserved
| Value kind | observed — Reported measurements, counts, and specifications keep the precision and scope stated by their source; an exact specification is not treated as a range. |
|---|---|
| Scope | The flag is the qualifying condition, not the counter itself: reaching eight remapped rows does not by itself qualify a GPU, and the NVIDIA Field Diagnostic determines RMA eligibility. Generation-specific — Blackwell attempts an on-package HBM channel repair on a third remap attempt where a spare channel is available. Cite the documentation version in force for the platform. |

| Source | NVIDIA, GPU Memory Error Management, RMA Policy Thresholds for Row Remapping (current documentation page). The 2025 source vintage is retained because the page does not identify a new publication date. · Current RMA policy: bank already holding eight uncorrectable-error remaps, remapping an already remapped row, or 512 total remappings; RMA requires the failure flag and NVIDIA Field Diagnostic validation. Blackwell channel repair is generation-specific. |
