Module names identify the datasheet configuration. Industrial order part numbers are issued in the SMC series; the configuration above carries module marking PC5-44800U-46. Order part numbers for the remaining configurations are confirmed at project review.
Electrical & Timing Specifications
Data rate is stated in MHz on the datasheet and shown here in MT/s, the transfer-rate unit used across this site. The numbers are unchanged.
Mechanical Specifications
Environmental Specifications & Compliance
Operating temperature and compliance are published as stated in the product datasheet. The measurement reference for the temperature range is not specified in the approved source.
Compatibility & Qualification
Module selection is determined by the target DIMM socket, memory controller, board layout and platform firmware. Compatibility verification is performed against the applicable target configuration according to project requirements.
Industrial Programme Controls
Configuration Control
Where configuration control is defined within the approved programme scope, qualified configurations are managed through the applicable BOM and change-review requirements.
Read more →Platform Qualification
Compatibility and stability verification are performed against the applicable target platform according to the defined qualification scope.
Read more →Lifecycle Coordination
Component availability, generation transitions and requalification requirements are reviewed against programme requirements.
Read more →Technical Change Management
Configuration changes are subject to technical review and requalification where required.
Read more →Production Verification
Production-level verification
- Incoming, in-process, final and outgoing quality control
- SPD programming and verification
- Module functional verification before shipment
Project-level qualification
- Target-platform compatibility verification
- Stability verification under the defined operating conditions
- Application-specific qualification where the programme requires it
Production-level verification applies to modules in manufacturing, where applicable to the approved production route for the product. Project-level qualification scope is defined according to project requirements and is not performed on every shipped unit.
Technical Documentation
The DDR5 U-DIMM specification document is issued on request during project review. Module-level values published on this page are stated in that document and corroborated by the industrial product label for the configuration listed under Ordering Information.
