Capacity and compatibility

This 64GB kit consists of four 16GB DDR5 4800 registered ECC RDIMMs validated for the Dell Precision 7960 rack and tower workstation. It targets professionals who need error-correcting memory for data-integrity workloads on that specific platform.

Sustained-load behaviour

Registered buffering and ECC circuitry maintain signal integrity and single-bit error correction during continuous operation in multi-socket server environments. The 1.10V operating voltage and CL40 latency are specified at the rated 4800MT/s speed for stable throughput over long sessions.

DDR5 interface limits

The 288-pin DDR5 RDIMM form factor and PC5-38400 data rate define the electrical and mechanical boundary of this upgrade. Systems that require unbuffered DIMMs, non-ECC modules or a different pin count cannot accept this kit.

Questions about this item

How much heat and power do the 1.1 V DDR5 4800 CL40 1Rx8 RDIMMs add when running all day?

Operating at 1.1 V with no heat spreader, the 1Rx8 DDR5 4800 CL40 modules draw minimal power and rely on chassis airflow for cooling in the Precision 7960.

What must the workstation already have for this 64 GB kit to function?

The Dell Precision 7960 Rack or Tower must provide four free 288-pin DDR5 RDIMM slots and a BIOS that supports registered ECC memory.

Will the 4800 MHz CL40 1Rx8 RDIMMs run correctly alongside slower DDR5 ECC modules already in the workstation?

All installed DDR5 RDIMMs will operate at the speed of the slowest module, so mixing with slower DDR5 ECC RDIMMs forces the kit to downclock.
