16 GB DDR4 ECC UDIMM kit with four 4 GB modules running at 2400 MHz CL17 for servers and workstations

  • CAS latencyCL17
  • Memory rank1Rx8
  • 16 GB kit of four 4 GB modules expands server capacity
  • DDR4 2400 MHz speed accelerates data throughput
  • ECC unbuffered design detects and corrects memory errors
  • Single-rank 1Rx8 organisation improves signal integrity
  • Standard 1.2 V operation reduces power draw

16 GB DDR4 ECC UDIMM Kit

This 16 GB kit contains four 4 GB DDR4 2400 MHz ECC unbuffered DIMMs built for servers and workstations. Each module uses a single-rank 1Rx8 organisation, runs at the standard 1.2 V, and carries a CL17 latency rating. The 288-pin form factor fits DDR4 ECC UDIMM slots in compatible enterprise platforms.

Suited for ECC server and workstation upgrades only

The modules are validated for systems that explicitly support DDR4 ECC unbuffered memory and will not function in desktop or laptop computers. Buyers who need non-ECC memory, registered DIMMs, or higher-density modules should look at other product lines.

DDR4 2400 MHz ECC unbuffered specification

The decisive specification is the DDR4 2400 MHz ECC unbuffered UDIMM standard with 1Rx8 ranking and CL17 timing. Confirm that your server or workstation motherboard lists this exact memory type before ordering.

Questions about this item

How do I install the 288-Pin DDR4 ECC UDIMM modules, and what step do people often get wrong?

Align the notch on each 288-Pin module with the slot key, press down evenly until the retention clips click, and follow your system manual for correct channel population — skipping the channel order is the common mistake.

What maintenance or replacement will this 16GB DDR4 2400 MHz kit need later?

No scheduled maintenance is required; if a module fails, replace it with another DDR4 2400 MHz ECC UDIMM 1Rx8 1.2V stick to keep rank and voltage consistent.

What limit appears first under sustained load with these CL17 1.2V modules?

The DDR4 2400 MHz speed rating and CL17 latency set the throughput ceiling; sustained heavy workloads will hit that bandwidth limit before voltage or thermal constraints become an issue.
