Dell Precision 7920 memory kit

This 48 GB kit contains six 8 GB DDR4 2933 ECC RDIMM modules built for the Dell Precision 7920 rack or tower workstation. Registered buffering and error-correcting code protect data integrity in professional workloads. The modules run at 1.2 V with CL21 latency and fit standard 288-pin DDR4 slots. Buyers needing non-ECC or unbuffered DIMMs for consumer boards should look elsewhere.

Registered ECC RDIMM at 2933 MT/s

The single specification that determines fit is the registered ECC RDIMM design running at DDR4 2933 (PC4-23400). Only systems that explicitly support registered error-correcting modules at this speed will recognise the full 48 GB capacity. Workstations requiring load-reduced, unbuffered or faster DDR4 modules cannot use this kit.

Six matched modules simplify installation

The package delivers six identical 1Rx8 modules pre-configured as a matched set, removing the need to source individual sticks or verify rank compatibility. No heat spreaders are included, so airflow clearance remains unchanged. No additional software, cables or brackets are supplied.

Questions about this item

How does the 2933 MT/s speed translate to real-world throughput in a Precision 7920?

The kit runs at DDR4 2933 with a PC4-23400 rating, delivering up to the JEDEC peak transfer rate per module at that data rate.

What does the PC4-23400 rating cap in practice?

PC4-23400 marks the JEDEC peak transfer rate for DDR4 2933; the memory controller in the Precision 7920 governs the actual sustained bandwidth.

Will the 288-pin registered DIMMs fit the Precision 7920 memory slots?

Yes, the 288-pin DDR4 RDIMM form factor matches the Precision 7920 DIMM sockets; the kit includes six 8 GB modules for the system's six-channel architecture.
