Dell Precision 7820 Memory Kit

This 48GB kit delivers six 8GB DDR4 2933MHz modules built for the Dell Precision 7820 tower workstation. Registered ECC RDIMM design adds error correction and signal buffering required by the platform. CL21 latency and 1.2V operation match the system specifications.

Registered ECC RDIMM Architecture

Each module uses a 1Rx8 organisation with 288-pin DDR4 RDIMM form factor so they install directly into the workstation's DIMM slots. Registered buffering reduces electrical load on the memory controller while ECC protects data integrity. No heat spreaders are fitted, leaving clearance for the factory cooling layout.

Sustained Workload Stability

ECC correction and registered signalling maintain consistent throughput during long rendering, simulation or compute jobs. The 1.2V rating keeps power draw steady under continuous load. Modules are validated for compatibility with the Precision 7820 platform to avoid timing mismatches that can appear after extended operation.

Questions about this item

Does the CL21 latency at 2933 MHz become the first bottleneck during sustained workloads?

The kit runs at CL21 timing and 2933 MHz; latency is fixed by those specifications, so the memory subsystem itself is the limiting factor under continuous load.

How much heat and power does the 6-module kit produce when running all day?

Each module operates at 1.20 V without a heat spreader; registered ECC RDIMMs at this voltage typically draw only a few watts per stick and run cool enough for passive airflow in a workstation chassis.

What must the workstation already have to accept this 288-pin RDIMM kit?

The system must be a Dell Precision 7820 tower workstation with DDR4 RDIMM slots that support ECC registered memory.
