Dell Precision 3930 Rack ECC Kit

This 64 GB kit contains four 16 GB DDR4 2666 ECC UDIMMs built for the Dell Precision 3930 Rack workstation. Unbuffered modules run at 1.2 V with CL19 timing and 288-pin form factor. The ECC function detects and corrects single-bit errors to protect data integrity in professional workloads.

Suited for memory expansion on the Precision 3930

Builders who need registered DIMMs or a different pin count should look elsewhere. Systems that require buffered memory or non-ECC modules will not accept this kit. The four-module layout fills all available slots on the supported platform.

Unbuffered ECC UDIMM at DDR4 2666

The single specification that decides fit is the unbuffered ECC UDIMM design at 2666 MT/s. Only motherboards that accept this exact module type, speed and voltage will operate correctly with the kit.

Questions about this item

Does the CL19 latency at DDR4 2666 become the bottleneck during sustained workloads?

CL19 at DDR4 2666 sets the baseline response time; under continuous load the fixed latency and 2666 MT/s throughput are the first limits you hit.

What heat or noise should I expect from the four 16 GB modules running all day?

Modules run at 1.2 V without heat spreaders, so they stay cool and silent; only case airflow noise is audible.

What must my Dell Precision 3930 Rack already have to accept this 64 GB kit?

Four free 288-pin DDR4 UDIMM slots and BIOS support for 16 GB ECC unbuffered modules at 1.2 V.
