Dell Precision 7875 memory kit

This 1 TB kit contains eight 128 GB DDR5 4800 RDIMM modules built for the Dell Precision 7875 workstation. ECC and registered operation protect data integrity in professional workloads. The CL40 latency and 1.10 V voltage match the platform specification. Modules use major OEM DRAM chips and are stress tested before shipping.

288-pin RDIMM installation

Each module fits a standard 288-pin DDR5 RDIMM slot and requires a motherboard that supports registered ECC memory. The 4Rx4 organisation increases density per channel while keeping the kit within the workstation's qualified configuration. No heat spreader is fitted so clearance inside the chassis is maximised. Installation follows the system manual without additional tools.

Capacity upgrade path

The kit replaces smaller DDR5 RDIMM sets to reach the full 1 TB capacity supported by the Precision 7875. It is not suited for consumer boards that accept only unbuffered non-ECC DIMMs. Buyers who need a lower total capacity or a different rank configuration should select an alternative kit.
