Product Features
Fixed base model: model numbers do not change with DRAM/RCD/PMIC vendors; supply variants use only G/D and hardware-revision suffixes
Fixed BOM: no mixing of dies, RCD, PMIC or PCB within one order/batch; any change goes through PCN
G-then-D: international-vendor BOM closes compatibility and delivery first; localized BOM is qualified in parallel and released as the D version
Platform QVL: every "Intel/AMD/domestic-CPU compatible" claim maps to a specific server/board model and test record
100% inspection, per-module burn-in and batch traceability, 5-year limited warranty
