Dell-compatible 16 GB DDR4-2400 ECC UDIMM with CL15 latency, 1.2 V operation and 2Rx8 organisation matching part SNPCX1KMDG/16G
This module is a 16 GB DDR4-2400 ECC UDIMM rated at PC4-19200 with CL15 latency and 1.2 V operation. It is built for servers and workstations that require error-correcting unbuffered memory and is validated for Dell systems using part number SNPCX1KMDG/16G.
Swapping smaller DDR4 UDIMMs for this 16 GB stick increases total memory and adds ECC protection for data integrity. The jump is worthwhile when your workloads need more capacity or when the platform requires ECC and your current modules lack it.
Confirm the system accepts DDR4 UDIMMs at 2400 MT/s and that the platform enables ECC on unbuffered modules. Check the number of free slots and the maximum capacity per slot before ordering.

Yes, the module uses the standard 288-pin DDR4 UDIMM form factor so it seats in any compatible 288-pin slot.
Align the notch with the slot key, press firmly until both side clips click, then verify the module sits flush; the step often missed is confirming both clips are fully latched.
Replace it if memory diagnostics report uncorrectable ECC errors, if the system logs recurring corrected errors, or when a capacity upgrade is required.
