1.5 TB DDR5 ECC kit for Dell Precision 7960

This 12-module kit delivers 1.5 TB of registered DDR5 memory built for Dell Precision 7960 rack and tower workstations. Twelve 128 GB RDIMMs provide the density required for large-scale simulation, rendering and virtualisation workloads. ECC and registered signalling protect data integrity across every channel.

Capacity and headroom at 4800 MT/s CL40

The kit runs at 4800 MT/s with a CAS latency of 40 at 1.1 V, giving ample bandwidth for memory-bound applications. Four-rank 4Rx4 organisation maximises capacity per slot, so the 12-slot platform reaches 1.5 TB without populating additional risers. Workloads exceeding this capacity must move to a higher-slot-count platform.

DDR5 registered DIMM interface limits

Each 288-pin RDIMM uses the DDR5 registered interface, which buffers address and command signals to support heavy loading. The registered design adds one cycle of latency versus unbuffered modules but enables the 12-module configuration. Systems without registered-DIMM support cannot use this kit.

Questions about this item

Will the 4800 MHz DDR5 RDIMMs run reliably alongside any existing 4800 MHz DDR5 modules I keep in my Precision 7960?

Yes, these 4Rx4 ECC registered DIMMs operate at 1.1 V and CL40. Matching speed, voltage and latency with other DDR5 4800 modules allows the platform to train all channels without timing conflicts.

How can I verify the 1.5 TB kit is detected and running at 4800 MT/s with ECC active after installation?

Enter the system BIOS or UEFI and confirm 12 DIMMs show 128 GB each at 4800 MT/s. Then boot the OS and run a memory diagnostic that reports ECC corrected errors to prove the registered ECC function is live.

Does the box include only the twelve 288-pin RDIMMs or are any cables, brackets or software licences supplied?

The kit contains the twelve 128 GB DDR5 4800 CL40 1.1 V 4Rx4 ECC registered DIMMs and nothing else. No cables, brackets, heat spreaders or software licences are included.
