512GB DDR4 2933 ECC RDIMM kit

This 512GB kit contains eight 64GB registered DDR4 modules rated at 2933 MT/s with CL21 latency and 1.2V operation. It is built for the Dell Precision 7920 workstation where ECC error correction and registered signalling are required for stability under heavy workloads.

Sustained load behaviour

Each module uses a 4Rx4 organisation with major OEM chips from Samsung, Micron or Hynix that have been stress tested under load. The registered buffer and ECC function maintain data integrity during continuous compute tasks such as rendering, simulation or virtualisation without the soft errors that unbuffered memory can allow.

Installation notes

The 288-pin RDIMM form factor fits the Precision 7920 DIMM slots directly, but the workstation requires all eight slots to be populated in the correct channel order for the 512GB capacity to be recognised. Mixing these registered modules with unbuffered DIMMs or using fewer than eight modules will prevent the system from posting.

Questions about this item

How much heat and power draw should I expect from the 8 modules running at 1.2 V all day?

Each 64 GB module operates at 1.20 V DDR4 standard voltage; the registered design and lack of heat spreaders mean thermal output is similar to other 288-pin RDIMMs at this density.

Does my Dell Precision 7920 need a specific BIOS revision or CPU generation to recognise all 512 GB?

The kit is validated for the Precision 7920 rack and tower workstation; consult the system manual for the minimum BIOS version that supports 64 GB 4Rx4 RDIMMs.

Can I mix these 2933 MHz CL21 sticks with slower DDR4 already installed in the workstation?

The motherboard will down-clock all modules to the lowest common speed and latency, so existing slower DDR4 will set the overall bus rate.
