Dell Precision 3930 upgrade

This 64 GB kit uses two 32 GB DDR4 2666 ECC UDIMM modules built for the Dell Precision 3930 Rack Workstation. It targets IT professionals and power users who need error-correcting memory for stable, high-capacity workloads.

Unbuffered 288-pin layout

Each module runs at 1.2 V with CL19 latency and a 2Rx8 organisation using major OEM Samsung, Micron or Hynix chips. The unbuffered design fits standard UDIMM slots without registered buffering, while the lack of heat spreaders keeps the profile low for dense rack chassis.

Replacing smaller non-ECC kits

Moving from standard unbuffered DIMMs to this ECC configuration adds single-bit error correction for data integrity in long-running compute tasks. The jump is worth it when uptime and silent data protection matter more than raw frequency headroom.

Questions sur cet article

What DDR4 speed and PC rating does this 64GB kit run at?

The modules operate at DDR4 2666 with a PC4-21300 rating, delivering 2666 MT/s data transfer on compatible systems.

Which physical slot and pin count do these 32GB sticks require?

Each 32GB module uses the standard 288-pin DDR4 UDIMM form factor and fits any DDR4 UDIMM slot keyed for unbuffered ECC memory.

How do I install the two modules in a Dell Precision 3930 Rack, and what step is often missed?

Power off, open the chassis, align each 288-pin module with the slot notch, press firmly until both side clips click, then verify in BIOS that both 32GB sticks are detected at 2666 MHz.
