16GB DDR4 2400 ECC UDIMM for Servers

This 16GB DDR4 2400 ECC UDIMM module provides error-correcting memory for server and workstation platforms that require 288-pin DIMMs. It operates at 1.2V with a CL17 latency and uses a 2Rx8 organisation. The unbuffered design fits systems that do not accept registered modules.

Replaces Dell A9755388 and A9755661 Part Numbers

This module is a compatible equivalent for Dell part numbers including A9755388, A9755661, CX1KM, SNPCX1KMC/16G, SNPCX1KMDG/16G, and YXC0V. The upgrade is worthwhile when a supported system needs additional capacity or a replacement for a failed stick. It is not for platforms that require registered DIMMs or speeds beyond 2400 MT/s.

DDR4 2400 UDIMM Limits

The DDR4 2400 interface caps data transfer at PC4-19200 bandwidth, which restricts throughput on memory-intensive workloads compared to faster DDR4 standards. ECC UDIMM topology also limits maximum system capacity because unbuffered modules place a heavier electrical load on the memory controller than registered alternatives. Systems needing higher speeds or larger populations must use a different memory type.

Questions sur cet article

Does the 288-pin DDR4 DIMM fit standard unbuffered ECC UDIMM slots?

Yes, the module uses the 288-pin DDR4 DIMM form factor designed for ECC UDIMM slots in compatible servers and workstations.

What is the correct way to seat the 1.2V module so the ECC function initialises?

Align the notch with the slot key, press down firmly until both retention clips click, then verify the system reports 16GB at 2400MHz with ECC active in BIOS.

When should the 2Rx8 rank configuration be rechecked after a firmware update?

Recheck if the server shows reduced capacity, corrected errors increase, or the memory runs below 2400MHz after a BIOS or firmware change.
