256GB RDIMM kit for Dell Precision 7820

This registered DDR4 kit delivers 256GB across four 64GB modules built for the Dell Precision 7820 Tower Workstation. Each module operates at 2933MT/s with CL21 latency and 1.2V power draw. ECC and 4Rx4 organisation protect data integrity in mission-critical workloads.

Sustained load behaviour with ECC registered design

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC corrects single-bit errors in real time without halting the system. The 4Rx4 layout maintains signal stability across all four modules when the workstation runs extended compute or virtualisation tasks.

DDR4 288-pin interface practical limits

The 288-pin DDR4 RDIMM form factor fits only platforms that support registered ECC memory at 2933MT/s. Systems requiring unbuffered UDIMMs or higher voltage modules cannot use this kit. Maximum capacity per channel depends on the workstation's memory controller specification.

Preguntas sobre este artículo

How much power does the 256GB DDR4 2933 kit draw at 1.20V when the workstation runs continuously?

Each 64GB module operates at 1.20V; total system draw depends on the Dell Precision 7820 memory controller and workload, not the modules alone.

What must the Dell Precision 7820 already have to accept this 4Rx4 RDIMM kit?

The workstation needs a compatible DDR4 RDIMM motherboard with four free 288-pin slots and a BIOS that supports 4Rx4 registered ECC modules at 2933 MT/s.

Can I mix these CL21 2933 modules with slower DDR4 RDIMMs already installed in the 7820?

The Dell Precision 7820 will clock all populated channels to the lowest common speed and latency; matching speed, rank and voltage avoids down-clocking.
