Capacity and Compatibility

This 256GB kit provides two 128GB DDR5 modules built for Dell Precision 7960 rack and tower workstations. Registered ECC RDIMM design suits enterprise workloads that require error correction and signal integrity. The modules operate at 1.1V and fit standard 288-pin DDR5 slots.

Sustained Workload Behaviour

CL40 latency and 4800 MT/s data rate deliver consistent throughput for memory-intensive applications such as virtualization, rendering and large dataset processing. Registered buffering reduces electrical load on the memory controller during continuous operation. 4Rx4 organisation increases density without adding physical modules.

Build and Daily Use

Modules use major OEM Samsung, Micron or Hynix components without a heat spreader, relying on chassis airflow for cooling. The 288-pin RDIMM form factor installs directly into compatible Dell Precision 7960 systems. Part number MR38400-744K2 identifies the exact kit for ordering and support reference.

Questions about this item

How much heat and power does the 256GB DDR5 4800 kit draw when the Dell Precision 7960 runs continuously?

Each 128GB module operates at 1.1V with no heat spreader, so thermal output stays low during sustained workloads in the 7960 rack or tower chassis.

What must the Dell Precision 7960 already have for this 288-pin RDIMM kit to function?

The workstation needs a DDR5-compatible motherboard with registered DIMM slots and ECC support; the kit plugs directly into those slots as a matched pair.

Will the 4Rx4 ECC registered modules work alongside any original DDR5 memory already installed in the 7960?

Yes, provided the existing modules are also DDR5 ECC RDIMMs; mixing ranks is supported by the platform, but matching speed and voltage ensures stable operation.
