Dell Precision 7960 memory upgrade

This 128GB DDR5 RDIMM is built for Dell Precision 7960 rack and tower workstations that require registered ECC memory. It targets IT professionals who need maximum capacity in a single slot for memory-intensive workloads. The module delivers 4800MHz speed with CL40 latency at 1.1V.

Registered ECC with 4Rx4 organisation

The registered buffer reduces electrical load on the memory controller, allowing stable operation at high density. On-die ECC corrects single-bit errors to protect data integrity in mission-critical applications. The 4Rx4 rank structure packs 128GB into one 288-pin module without a heat spreader.

Major OEM DRAM chips and lifetime replacement

Chips sourced from Samsung, Micron or Hynix are stress-tested under load before shipping. The bare PCB fits standard DDR5 RDIMM slots in the Precision 7960 chassis. Buyers needing unbuffered UDIMMs or lower-capacity modules for consumer platforms should look elsewhere.

Questions about this item

Will the 128GB DDR5 4800 module need any firmware updates or component replacements during its service life?

The RDIMM has no moving parts or firmware; it requires no scheduled maintenance or component replacement under normal server workloads.

What is the first limit reached when the 4Rx4 ECC registered DIMM runs at full 4800 MT/s continuously?

The module operates at its rated 4800 speed and CL40 latency; the primary limit under sustained load is the memory controller's thermal and bandwidth ceiling.

How much heat and power does the 1.1V 288-pin DDR5 RDIMM produce during all-day operation in a Dell Precision 7960?

At 1.1 V the module draws low power and runs cool; its registered design and lack of heat spreader keep thermals manageable in the workstation's airflow.
