Dell Precision 3930 Rack memory upgrade

This 8 GB DDR4 2666 ECC UDIMM is built specifically for the Dell Precision 3930 Rack workstation. It targets IT professionals and system integrators who need validated, error-correcting memory for stable operation in rack-mounted environments. The module delivers 2666 MT/s throughput at CL19 latency.

Unbuffered 288-pin design with major OEM chips

The stick uses Samsung, Micron or Hynix components on a standard 288-pin UDIMM PCB without a heat spreader. Unbuffered topology keeps latency low for single-threaded workloads while ECC protects data integrity. The 1.2 V operating voltage matches the platform specification and the 1Rx8 rank layout fits the workstation's memory slots directly.

Single 8 GB module ready for installation

The package contains one 8 GB stick (part ME21300-818K1) so you can populate a free slot or start a new configuration. No additional cables, brackets or software are bundled. Compatibility testing under load is performed by the manufacturer to reduce the risk of boot issues in the target Dell system.
