NEMIX RAM 16GB DDR4 ECC UDIMM Kit

This 16GB kit contains two 8GB DDR4 2666MHz ECC UDIMM modules. It is built for servers and workstations that require error-correcting unbuffered memory. The dual-rank 1Rx8 organisation and 1.2V operation match the PC4-21300 standard. It suits administrators upgrading compatible platforms.

Ideal for ECC UDIMM servers.

This memory fits systems that specifically accept DDR4 2666MHz ECC UDIMM modules. Builders whose boards only support non-ECC unbuffered DIMMs cannot use this kit. Servers requiring registered or load-reduced DIMMs must choose a different module type. Laptop or compact systems needing SO-DIMM form factors are also incompatible.

Deciding spec: DDR4 2666MHz ECC UDIMM at 1.2V

The single specification that determines fit is the DDR4 2666MHz ECC UDIMM designation at 1.2V. Your motherboard must explicitly list support for PC4-21300 ECC unbuffered DIMMs. Verify the memory QVL before purchase; a mismatch in ECC type, buffering or voltage will prevent the system from posting.

Questions about this item

My server takes 288-PIN ECC UDIMM modules — will this kit fit?

Yes, each stick is a 288-PIN ECC UDIMM that runs at 1.2 V and 2666 MHz with CL19 timing.

If I keep my existing DDR4 2666 ECC UDIMMs, will the system run both kits at the same speed?

The memory controller will operate all installed modules at the lowest common speed and timing, so identical DDR4 2666 CL19 kits will run together at 2666 MHz.

How do I confirm the kit is detected as 16 GB ECC after installation?

Check the BIOS memory summary or run a tool such as dmidecode; it should show two 8 GB DDR4 2666 modules with ECC enabled and a CAS latency of 19.
