Dell Precision 7920 memory kit

This 256GB kit contains sixteen 16GB DDR4 2933 RDIMM modules built for the Dell Precision 7920 rack or tower workstation. It is intended for administrators expanding memory capacity in supported Dell systems.

Registered ECC DDR4 2933

Each module runs at 1.2V with CL21 latency and a 2Rx8 organisation, providing registered ECC operation required by the Precision 7920 platform. The registered buffer and error correction are the decisive specifications for compatibility.

Tool-free DIMM installation

Modules insert into the 288-pin DDR4 slots after opening the chassis; the workstation firmware recognises the kit automatically when all sixteen slots are populated. Common issues arise if slots are filled in the wrong sequence or if mixed-rank modules are combined with this kit.

Questions about this item

What does the 2933 MT/s speed mean when the kit is installed in a Dell Precision 7920?

The modules run at DDR4 2933 (PC4-23400) with CL21 latency, delivering the rated throughput once the workstation's memory controller is configured for that speed.

How does the ECC RDIMM interface affect usable capacity and bandwidth in this system?

Registered DIMMs with ECC add a clock cycle for buffering and provide single-bit error correction, so the full 256 GB is addressable with data integrity protection.

What physical slot and voltage requirements must the Precision 7920 meet for these 288-pin modules?

The workstation needs 16 free DDR4 RDIMM slots operating at 1.2 V to accept the 16 x 16 GB kit.
