Dual-rank 32 GB DDR4 ECC UDIMM kit running at 2133 MHz with CL15 latency for servers and workstations

  • CAS LatencyCL15
  • Rank2Rx8
  • 32 GB dual-channel kit expands server memory capacity
  • 2133 MHz DDR4 speed accelerates data throughput
  • ECC unbuffered design detects and corrects single-bit errors
  • 2Rx8 dual-rank organisation increases memory density per slot
  • 2 V standard voltage reduces power draw per module

Server ECC UDIMM Kit

This 32 GB kit contains two 16 GB DDR4 2133 MHz ECC UDIMM modules rated at CL15 with a 2Rx8 organisation. It is built for servers and workstations that require error-correcting unbuffered memory. The dual-rank design helps increase memory density per channel. Operation is at the standard 1.2 V DDR4 voltage.

Compatibility Check Required

Verify that your system supports DDR4 ECC UDIMM modules at 2133 MHz and can accept 2Rx8 dual-rank DIMMs. Consult the motherboard or server manual for qualified memory lists and channel population rules. This kit is not compatible with desktop or laptop computers that lack ECC unbuffered support. Ensure the 288-pin DIMM slots match the module form factor.

Capacity and Rank Upgrade

The kit replaces smaller or single-rank DDR4 ECC UDIMM configurations to double usable capacity and improve multi-threaded workload throughput. The jump is worthwhile when your applications hit memory limits or when additional ranks help utilise all memory channels. Systems already populated with matched 2Rx8 modules at 2133 MHz will not gain further benefit from this kit.

Questions about this item

Does the 32 GB kit include both 16 GB modules or do I need to buy a second stick?

The kit contains two 16 GB modules for a total of 32 GB; nothing else is required for installation.

Should I choose the PC4-17000 or PC4-2133P-E labelled version for my server?

Both labels describe the same DDR4 2133 MHz specification; either marking will work in a compatible system.

Will the CL15 latency at 2133 MHz actually improve my workload throughput?

CL15 at 2133 MHz delivers standard DDR4 timing for ECC UDIMM modules, supporting reliable server and workstation performance.
