Capacity & configuration

This kit delivers 1 TB of DDR5 memory in eight 128 GB registered DIMMs. Each module runs at 4800 MT/s with CL40 latency and operates at 1.1 V. The 4Rx4 organisation and ECC support are built for data-integrity workloads on the Dell Precision 7960 rack or tower workstation.

Suited workloads & limits

The kit targets professionals who need maximum registered ECC capacity for virtualisation, large datasets or scientific computing on the validated platform. It does not suit systems that require unbuffered UDIMMs, non-ECC memory, lower-density modules or a different DDR generation.

Build integration

The 288-pin RDIMMs plug directly into the workstation’s DDR5 slots and draw 1.1 V, leaving headroom for the platform’s power delivery. Registered signalling reduces electrical load on the memory controller, freeing it to manage the full 1 TB configuration without additional buffering hardware.

Questions about this item

What motherboard slot does the 288-pin DDR5 RDIMM require on the Dell Precision 7960?

The kit uses 288-pin DDR5 RDIMM modules that install directly into the Precision 7960's DDR5 memory slots; no adapter or converter is needed.

Can I mix these 4Rx4 CL40 modules with existing 2Rx8 or 1Rx4 sticks in the same workstation?

Mixing different rank configurations or CAS latencies is not recommended; for stable operation populate all channels with identical 4Rx4 CL40 modules.

How do I confirm the full 1 TB is recognised and ECC is active after installation?

Enter the system BIOS or run a memory diagnostic; the firmware should show 1 TB total capacity with ECC status reported as enabled.
