Server memory kit for enterprise workloads

This 128GB quad-channel kit contains four 32GB DDR4 2666 MHz registered ECC DIMMs. It is built for servers and workstations that require error-correcting registered memory. The modules operate at the standard 1.2V DDR4 voltage.

Registered ECC RDIMM form factor

Each module uses a 288-pin DDR4 DIMM interface with registered buffering and ECC functionality. The dual-rank x4 organisation and CL19 latency are fixed characteristics that must match the system's qualified vendor list. Desktop and laptop platforms cannot accept these modules.

Suits administrators upgrading compatible DDR4

Buyers who need non-ECC unbuffered memory for consumer desktops or laptops should look elsewhere. Systems that only support single-rank or lower-density DIMMs will not be compatible with this 2Rx4 configuration.

Questions about this item

What does the 128 GB kit mean for a server running virtual machines?

The kit provides four 32 GB modules totalling 128 GB, giving a server more capacity to host multiple virtual machines or large databases without swapping to disk.

What does the PC4-21300 rating on these DDR4 2666 modules actually limit?

PC4-21300 is the JEDEC peak transfer rate for DDR4 2666, so the memory bus cannot exceed that bandwidth regardless of the CPU or chipset.

Will these 288-pin registered DIMMs fit in a standard server chassis?

Each module uses the 288-pin DDR4 RDIMM form factor, which matches the DIMM slots on compatible DDR4 server and workstation motherboards.
