256GB DDR4 2666 ECC UDIMM Kit

This 256GB kit contains eight 32GB DDR4 2666 modules built for servers and workstations. Each stick is an unbuffered ECC UDIMM with a 2Rx8 dual-rank layout and standard 1.2V operation. The memory uses major-brand chips and carries a CL19 latency rating. It is designed to increase capacity and reliability in compatible enterprise systems.

Suited for ECC UDIMM platforms only

This kit fits systems that specifically accept 288-pin DDR4 ECC unbuffered DIMMs. It will not work in desktop or laptop computers that require non-ECC or registered memory. Builders needing registered RDIMMs, LRDIMMs, or non-ECC modules should look at a different memory type.

2Rx8 dual-rank x8 organisation

The 2Rx8 dual-rank x8 organisation determines how the memory controller addresses each module. Verify that your server or workstation supports this rank configuration and the 2666 MHz speed before purchasing. Compatibility with the specific rank layout is the single specification that decides whether this kit will function correctly.

Questions about this item

How do I choose between the 8-module kit and other capacities?

This kit provides 256 GB total across eight 32 GB modules. Select it when your server or workstation has eight available DIMM slots and the platform supports 32 GB unbuffered ECC modules.

What does the 2666 MHz rating mean once the RAM is installed?

The memory operates at 2666 MT/s with CL19 timing at 1.2 V. Actual throughput depends on the processor's memory controller and how many channels are populated.

Is this DDR4 ECC UDIMM compatible with standard DDR4 slots?

Yes. It uses the 288-pin DDR4 UDIMM form factor with ECC and dual-rank x8 organisation. It fits DDR4 server and workstation boards that explicitly support unbuffered ECC memory.
