8GB DDR4 RDIMM for servers

This module is an 8GB DDR4 2666MHz ECC Registered DIMM built for servers and workstations. It uses a 288-pin form factor and runs at 1.2V with CL19 latency. The 2Rx8 organisation and registered buffer help maintain signal integrity on multi-DIMM channels. It is sold new and intended for DDR4 platforms that require registered memory.

Suits ECC registered DDR4 platforms.

It suits administrators upgrading or populating DDR4 servers that mandate registered ECC modules. It will not work in desktop or consumer boards that accept only unbuffered non-ECC DIMMs. Buyers needing higher capacities per slot or different speed grades should look at other modules. Compatibility must be verified against the system's qualified vendor list before purchase.

Registered ECC buffer decides fit

The single specification that decides fit is the registered ECC buffer combined with the DDR4 2666MHz JEDEC standard. Only systems designed for DDR4 registered RDIMMs can use this module; unbuffered or non-ECC platforms will not post. Match the 288-pin DDR4 registered requirement exactly to avoid incompatibility.

Questions about this item

My motherboard has 288-pin DDR4 slots — will this 2Rx8 registered ECC module work in them?

This module fits 288-pin DDR4 slots and requires a server or workstation platform that supports registered ECC memory; standard desktop boards usually do not.

I already have CL19 DDR4 2666 sticks — can I add this 8GB RDIMM alongside them?

Mixing ranks and registered with unbuffered modules can cause instability; for best results populate all channels with identical 2Rx8 registered ECC DIMMs at 2666 MHz.

After installing the module, how do I confirm it is running at PC4-21300 with ECC active?

Check the BIOS memory information or use a tool such as CPU-Z — it should report 2666 MT/s, CL19, 1.2 V and show ECC enabled.
