  • 2 V DDR4 standard voltage reduces power draw
  • CL15 latency at 2133 MHz delivers responsive performance

16GB DDR4 ECC kit for servers

This 16GB kit contains two 8GB DDR4 2133 MHz ECC UDIMM modules built for servers and workstations. The memory runs at 1.2V with CL15 latency and a single-rank 1Rx8 organisation. It is designed only for systems that accept DDR4 ECC unbuffered DIMMs and will not work in desktop or laptop computers.

Straightforward DIMM installation

The 288-pin UDIMMs seat like standard server memory; follow the motherboard manual for correct channel population and seating order. Common issues arise when the kit is placed in a desktop board that lacks ECC support or when mixed with registered or load-reduced modules, which prevents the system from posting.

Verify DDR4 ECC UDIMM support first

Check the system documentation to confirm it accepts DDR4 2133 MHz ECC unbuffered memory in a 288-pin DIMM slot. Ensure the platform can address single-rank 1Rx8 modules at 1.2V and that the BIOS is current enough to recognise the kit. Systems requiring registered or fully buffered DIMMs are not compatible.

Questions about this item

How do I confirm the kit runs at 2133 MHz with CL15 after installation?

Enter the system BIOS or UEFI and check the memory information screen; it should show DDR4 2133 MHz and CAS latency 15 for each module.

What comes in the package and is anything else required?

The box contains two 8 GB DDR4 ECC UDIMM modules (288-pin, 1.2 V, single rank x8); no extra parts are needed if the server or workstation has free DDR4 DIMM slots.

Should I choose the 16 GB kit or a different capacity for my server?

This 16 GB kit (2 × 8 GB) suits systems needing ECC unbuffered DDR4 2133 MHz in matched pairs; select a larger kit only if your platform supports more total memory and you need it.
