Dell Precision 7920 ECC RDIMM kit

This 128 GB kit contains two 64 GB DDR4 2933 MHz registered DIMMs built for the Dell Precision 7920 workstation. ECC and registered operation protect data integrity in professional workloads. Modules run at 1.2 V with CL21 latency.

Build integration for registered memory

The 288-pin RDIMMs require a motherboard that supports registered ECC DDR4 and 4Rx4 organisation. They free standard unbuffered slots for other uses and draw 1.2 V per module. No heat spreader is fitted, so airflow across the PCB is necessary.

What the kit includes

The package delivers two matched 64 GB modules totalling 128 GB, ready for dual-channel population. No additional cables, software or accessories are supplied. The kit is validated for the specified workstation platform only.

Questions about this item

Will the CL21 latency limit throughput when the Dell Precision 7920 runs sustained memory-heavy workloads?

The modules operate at DDR4 2933 with CL21 timing; sustained throughput is governed by the platform memory controller and the registered ECC design rather than the CAS figure alone.

How much heat and power should I expect from the 128 GB kit during all-day operation?

Each 64 GB RDIMM runs at 1.20 V without a heat spreader; registered ECC modules typically draw a few watts per stick and stay cool under normal server airflow.

What must the Dell Precision 7920 already have for this 2 x 64 GB kit to work?

The workstation needs free 288-pin DDR4 RDIMM slots that support 4Rx4 registered ECC modules and a BIOS configured for 2933 MHz operation.
