Dell Precision 3930 Rack memory kit

This 128GB kit contains four 32GB DDR4 2666 modules built for the Dell Precision 3930 Rack workstation. Each stick runs at 1.20V with CL19 timing and uses 2Rx8 ECC unbuffered chips from major OEM suppliers. The 288-pin UDIMM form factor fits the system's standard DIMM slots.

IT teams expanding workstation capacity

The kit suits administrators who need maximum ECC capacity in a validated Dell configuration. Buyers without a Precision 3930 Rack should look elsewhere because the modules are qualified for that specific platform. Systems requiring registered DIMMs or non-ECC memory will not accept this kit.

Four matched modules in one package

The bundle delivers a complete 128GB upgrade without mixing different production lots. Matched sticks reduce the risk of timing mismatches during POST. No heat spreaders are included so clearance remains identical to the factory modules.

Questions about this item

My Dell Precision 3930 Rack has empty 288-pin DDR4 slots — will this 128GB kit install directly?

Yes, the kit contains four 32GB 288-pin DDR4 2666 ECC UDIMMs that seat in the workstation's standard unbuffered memory slots.

I plan to keep my existing 2666 ECC UDIMMs alongside this kit; will they run together without errors?

Matching speed, voltage (1.20V), rank (2Rx8) and CAS latency (CL19) lets the new modules operate in sync with identical DDR4 2666 ECC UDIMMs already installed.

After seating the four modules, how can I confirm the full 128GB is recognised at 2666 MT/s with ECC active?

Check the BIOS memory summary or run `dmidecode -t memory` on Linux; it should show four 32GB DDR4 2666 ECC UDIMMs totalling 128GB at PC4-21300 speed.
