128GB DDR5 ECC RDIMM Kit

This 128GB kit contains eight 16GB DDR5 4800 registered DIMMs built for the Dell Precision 7875 workstation. ECC and registered buffering protect data integrity in professional workloads. Modules operate at 1.1V with CL40 latency. The 288-pin form factor matches the platform's memory slots.

Sustained Load Stability

Rigorous stress testing under load validates reliability for continuous operation in mission-critical environments. Registered buffering reduces electrical load on the memory controller during extended sessions. ECC corrects single-bit errors that accumulate over time. The 1.1V operating voltage supports consistent thermal behaviour.

DDR5 4800 Interface Limits

The PC5-38400 standard defines the maximum transfer rate for this module class. CL40 timing sets the minimum latency ceiling at this frequency. Registered architecture adds one cycle of command delay versus unbuffered designs. Single-rank 1Rx8 organisation limits maximum density per channel.

Questions about this item

How much power and heat will the 1.1V DDR5 4800 modules add when the Precision 7875 runs continuously?

Each module operates at 1.1V, the standard DDR5 voltage, which helps limit power draw and thermal output during sustained workloads.

What must the Dell Precision 7875 already have to accept this 8 x 16GB RDIMM kit?

The workstation needs eight free 288-pin DDR5 RDIMM slots and a processor that supports ECC registered memory at DDR5 4800.

Will the CL40 1Rx8 modules run alongside any existing DDR5 4800 RDIMMs already installed in the 7875?

Yes, provided the installed modules are also DDR5 4800 ECC registered 1Rx8 RDIMMs; mixed speeds or ranks will force the system to run at the lowest common settings.
