8GB DDR4 ECC UDIMM for Servers

This 8GB DDR4 2666 ECC UDIMM module is built for server and workstation systems that require error-correcting memory. It operates at 1.20V with a CAS latency of CL19 and uses a single-rank 1Rx8 organisation. The 288-pin DIMM is a direct replacement for several Kingston part numbers.

DDR4 2666 Speed and Unbuffered Design

The module runs at the DDR4 2666 (PC4-21300) data rate, which is the maximum speed supported by this standard. Because it is unbuffered ECC, it cannot be mixed with registered or load-reduced DIMMs in the same system. The memory controller must support ECC UDIMM operation at this frequency for the module to function correctly.

Check Motherboard ECC UDIMM Support Before Ordering

Verify that your motherboard or server platform explicitly supports ECC unbuffered DDR4 DIMMs at 2666MHz. Systems that only accept registered ECC or non-ECC memory will not work with this module. Confirm the maximum supported capacity per slot and the total number of available 288-pin slots in your chassis.

Questions about this item

Should I pick a 1Rx8 or 2Rx8 module for my server?

This module is a single-rank 1Rx8 design, which places less electrical load on the memory controller and is often preferred for maximum slot population.

What does the 2666 MHz rating deliver once installed?

The module runs at DDR4 2666 MHz with CL19 latency, providing 21300 MB/s peak bandwidth for server and workstation workloads.

How does the ECC UDIMM interface affect compatibility?

It uses a standard 288-pin DDR4 DIMM slot with ECC unbuffered signalling; the system must support ECC UDIMM memory for error correction to function.
