Four 16 GB DDR4 ECC UDIMM modules at 2933 MHz CL21 add 64 GB of registered-grade reliability to compatible servers and workstations

  • CAS LatencyCL21
  • Rank2Rx8
  • 64 GB kit with four 16 GB modules for high-capacity server workloads
  • DDR4 2933 MHz speed accelerates data throughput in compatible systems

  • Dual-rank 2Rx8 organisation increases memory density per channel
  • Standard 1.2 V DDR4 voltage reduces power draw per module

64GB DDR4 ECC UDIMM Kit

This 64GB kit contains four 16GB DDR4 2933MHz ECC UDIMM modules built for servers and workstations. The dual-rank 2Rx8 configuration operates at 1.2V with CL21 latency across 288-pin DIMM slots. It is designed specifically for systems that require error-correcting unbuffered memory.

Upgrade from lower-capacity DDR4 ECC UDIMM

Replacing smaller DDR4 ECC UDIMM kits with this 64GB set increases the memory ceiling for virtualisation, databases and multi-user workloads. The jump is worth it when your current capacity forces swapping or limits the number of concurrent virtual machines or containers. Systems not supporting DDR4 ECC unbuffered DIMMs cannot use this kit.

Straightforward DIMM installation

Installation follows standard 288-pin DIMM seating in the correct channel order documented in the system manual. The most common issue is populating slots in the wrong sequence, which prevents the system from recognising the full 64GB or running at 2933MHz. Verifying the platform's qualified vendor list before purchase avoids compatibility surprises.

Preguntas sobre este artículo

What slot type does the 288-pin DDR4 ECC UDIMM require on the motherboard?

The kit uses standard DDR4 288-pin UDIMM slots; each 16 GB module fits one unbuffered DIMM socket on a compatible server or workstation board.

What is the correct seating order for the four 16 GB sticks in a quad-channel server board?

Populate the primary slot of each channel first — usually the slot farthest from the CPU — then add the second module per channel, following the board manual's channel map.

How can I tell when a 16 GB module in the 64 GB kit needs replacement?

Persistent correctable ECC errors logged by the OS or firmware, or uncorrectable errors that trigger a machine check, show that a specific stick is failing and should be swapped.
