32 GB DDR4 ECC kit for servers and workstations

This 32 GB kit contains four 8 GB DDR4 2133 MHz ECC unbuffered DIMMs rated at CL15 and 1.2 V. The modules are built for DDR4 servers and workstations only and will not function in standard desktop or laptop computers. Each stick is a 288-pin dual-rank x8 module validated for error-correcting operation.

Build integration with registered ECC memory

The kit plugs into standard 288-pin DDR4 DIMM slots that support ECC UDIMM topology. Four modules fill quad-channel configurations or matched pairs across dual-channel platforms, freeing empty slots for future expansion. Compatibility must be confirmed against the system manual before installation.

Upgrade path from smaller or non-ECC DDR4 kits

Replacing a lower-capacity or non-ECC DDR4 kit with this 32 GB ECC set adds error correction and higher density for data-integrity workloads. The jump is worthwhile when the platform explicitly requires ECC unbuffered memory and the workload demands more than the current installed capacity.

Questions about this item

What is the CAS latency that limits sustained throughput on this kit?

The modules run at CL15, so the column-access delay is 15 cycles at 2133 MHz.

How much heat and power should I expect from four dual-rank modules running continuously?

Each stick operates at the standard 1.2 V DDR4 voltage, keeping power draw and thermal output at baseline levels for this speed grade.

What must my system already provide for these 288-pin ECC UDIMMs to function?

A DDR4 server or workstation platform that supports ECC unbuffered DIMMs with dual-rank x8 organisation.
