Compatibility and service notes
- Meteor Lake-H system only; the multi-tile BGA package, embedded controller/firmware, cooling and memory topology are platform-specific. Not field-upgradable.
- DDR5-5600 or LPDDR5x-7467; memory type and maximum capacity depend on board Memory speed, channel wiring and any memory-on-package configuration must match the system-board design.
- Check the laptop manufacturer's exact model-level CPU list, board revision, BIOS/firmware, thermal assembly and power profile. Package name alone does not guarantee electrical, firmware or mechanical compatibility.
- PCI Express capabilities do not promise a particular connector, storage slot or external port; those are implemented by the notebook platform.
