System-specific memory kit for Dell Precision 3930

This 64 GB kit contains four 16 GB DDR4 2666 MT/s UDIMMs built for the Dell Precision 3930 Rack workstation. It targets IT professionals and system integrators who need a validated, single-part-number upgrade for that exact platform.

Non-ECC unbuffered DDR4 2666 with CL19 timing

The modules run at 1.2 V, use a 1Rx8 organisation and carry no ECC or registered buffers. That combination matches the Precision 3930 Rack memory controller requirements; systems requiring ECC or registered DIMMs cannot use this kit.

Four matched modules ship as a single kit

The package delivers all four 288-pin UDIMMs together, so the workstation can be populated to 64 GB in one step without sourcing individual sticks. No heat spreaders, software utilities or additional accessories are included.

Questions about this item

What does the 2666MHz speed mean for my Dell Precision 3930 Rack?

The kit runs at DDR4 2666 (PC4-21300) so the memory controller will operate at that data rate; the workstation will use the full 2666MHz if the CPU and BIOS support it.

How does the 288-pin UDIMM interface limit what I can install?

These are 288-pin DDR4 UDIMM modules, so they only fit DDR4 UDIMM slots and cannot be used in DDR5, RDIMM or SO-DIMM sockets.

Will the four 16GB sticks fit the Precision 3930 Rack chassis?

The kit contains four standard-height 288-pin UDIMMs with no heat spreader, matching the Dell Precision 3930 Rack's four DIMM slots.
