16GB DDR4 ECC UDIMM Kit

This 16GB kit contains two 8GB DDR4 2133 MHz ECC UDIMM modules built for servers and workstations. Each module runs at 1.2V with a CAS latency of 15 and a dual-rank 2Rx8 organisation. The 288-pin DIMM form factor fits compatible DDR4 ECC unbuffered slots only.

Servers and workstations needing ECC unbuffered

Designed for systems that specifically support DDR4 ECC UDIMM modules; it will not work in desktop or laptop computers that require non-ECC or registered memory. Buyers who need higher capacities, faster speeds, or registered DIMMs should look at other kits.

Straightforward DIMM installation

Insert each module into the appropriate DDR4 ECC UDIMM slots following the system manual's channel and population guidelines. The most common issue is purchasing this kit for a platform that does not support ECC unbuffered memory, which prevents the system from posting.

Questions about this item

What system do I need to run this DDR4 2133 MHz ECC UDIMM kit?

You need a server or workstation that supports DDR4 ECC Unbuffered DIMM modules at 1.2V. Desktop and laptop computers are not compatible.

Will the 2Rx8 dual-rank modules work with existing single-rank DDR4 ECC UDIMMs in my server?

Yes, the 2Rx8 modules can operate alongside single-rank DDR4 ECC UDIMMs if your platform allows mixed ranks; consult the system manual for supported population rules.

How can I confirm the kit is running at the rated 2133 MHz with CL15 latency after installation?

Check the memory speed and timings in the BIOS/UEFI or use a system-information tool such as CPU-Z to verify DDR4-2133 operation at CL15.
